First Grow, four plants

Thanks for the advice victor, I'll give them more nutes. I don't have a ppm meter so I don't know when to step it up but I guess I increase until I see they have a little nute burn. So you give them four times the advised amount, thats a huge difference, no wonder my plants are all weak., they all had diarrhea
It's been hard to find people growing coco and hand watering. maybe I should have started with soil but the hydro guy said it was much easier than soil and grew better. It feels like they are sad every other day and need constant monitoring, but then the PH is all acting weired, last time I gave them PH 6 and the runoff was 5.5. I just don't get it. How can it change so much in two days?
Could you let me know how to find Hubert?
cheers

WWI is still droopy

Watering: PH 6.0, ¾ Ionic Growth, Super Thrive
Eva: 800 ml; no runoff
Kahealani: 1100 ml; runoff 5%; PH in runoff: 5.5
WWI: 800 ml; runoff 5%; PH in runoff: 5.4
WWII: 600 ml; runoff: 10%; PH in runoff 5.5

I don’t understand how the PH got so low? What is happening? ANY ONE?

this is what i think (i have never used coco just soil) i rarely check my runoff this probably is bad but when i do my ph is usually higher then what i add, .....i add 6.5ph water and it comes out around 7.0 or little higher. i think its just because your medium has a different ph level then your water ur adding to your medium i realy dont think its a big problem but dont quote me on this.

Smoke on

Saw your post in my coco journal. Just checking in here. You should copy and paste your journal url into your sig like mine - make it easier to find. I'm just getting started in coco and just got my ph/ppm tester today so hopefully some more experienced people can help you to get your ph up but those numbers don't seem too bad. Plus your plants look good to me. You saw my plants in my journal, now that you have gotten things looking good they will take off quick! If you're really interested in accurately measuring ph/ppm you can get the meter I have for the cheapest price around here Hanna COMBO pH/EC/TDS/Temp Waterproof Tester HI98129 - eBay (item 180227165657 end time May-24-08 11:44:14 PDT) They sell a weird variety of stuff but shipping was fast. Anyways, I'll keep checking in, keep it up!

Oh, I also noticed sometimes you say no runoff. I make sure my plants have a sizeable amount of runoff every time. This guarantees that all old nutes and deoxygenated water is flushed out and replaced with fresh stuff. Plus, you can be sure that the entire pot is getting watered evenly.

nice
good looking plants

i agree you should alwas have at least 10-15% of wateru put in, drip out the bottom.

Also what are your plans for your grow??? how long you vegging for?? because u may need to put those plants into a different pot size.

Ok, last thing. If there was one piece of advice I would have given myself a month ago (when I was 100% new, not saying you are) it would be that plants take at least 2-3 days to show a reaction to what you do to them. If they are burned and you flush it takes 2-3 days to stop. If they're yellow and deficient, they won't green up until 2-3 days after feeding. So don't overdo it and try to get them back to normal too fast.

I will definitely let them all have at least 10% runoff from now on, thanks.

I think I let them grow two or three more weeks (total of 6-7 weeks) they are still tiny. I probably should get 2-3 gallon pots. I was thinking to let them be in these pots two more weeks but the roots grow really fast in coco so I might have to go bigger in a week instead. the roots are already showing on the bottom of the pot and I just planted them 3 days ago.

I'll do that, I'm new so I have to figure out how to use the options.
The PH is too low, I have a phosphorous deficiency on two plants now, the leaves are dark green and the stem have purple lines. Phosphorous is taken up by the plant between PH 5.9 and 6.2. I have no idea if I can give them water with a higher PH and if it will then adjust it to the right PH.

I can't afford a ppm yet...., but that one looks good and the price is great, I payed 130 for a PH meter and it's not even so accurate as this one.
I love that episode on Dave chapelle, I don't know how many I've seen it, but it's never enough
thanks!!

I'm just learning from the experts on this forum how to actually use the data from my new tester. Here's something that TetraHyC said that should help you with your ph problem since you do have a ph tester.

"Run off, I use it to get an idea of how much acid to use, remember pH is a magnitude like the Richter scale. 6.0 pH has 10 times the hydrogen ions (protons) as 7.0 pH.
pH - Wikipedia, the free encyclopedia
See how I was feeding with 5.3pH in then mid 6s out.
If ppm, pH get too high, I flush them.

This strain LOVES ACID, look how the pH rises big time in the run-off, ate up the H+ ions."

Remember, coco is pretty much inert. Whatever you put in, the coco will take on those properties, given you have enough runoff to get the old stuff out. So if you want to raise the ph of the medium, raise the ph of your feed water. Compare what you put in to what comes out (runoff). Hope that helps some.

I can see that WWII have similar spots that WWI had, in other words magnesium deficiency, I sprayed all with Epsom salt and water.


Pictures: very sad WWI, stems of Eva and Kahea purple stems

18 May
I gave all full strength Ionic Growth, a couple of drops Super Thrive and PH 6.2
The runoff was again 5.4-5.5 in all of them.
I gave them some more water and the runoff went down to 5.2-5.3?????

What am I supposed to do??? What is wrong? Is there any salt build up?

So I flushed all of them because that PH is way too low and they can’t get any Phosphor or Magnesium. I can also clearly see the deficiencies caused by the PH being low.
Then I gave them ¼ nutes and super thrive, PH 6.2
I got the PH in kahea to 6.2 and WWI and WWII to 6.0

But the runoff from Eva was 6.5???????

What the hell is going on?

20 May
WWII two leaves are worse; they are rusty on the tip and grayish yellow. Two other leaves have small yellow spots. Older leaves are darker green and the new ones are lime green.

Watering with full strength Ionic Growth, few drops of Super Thrive and PH 6.0

Eva: 1 liter; runoff 10%, PH 6.4, gave it 250 ml more and PH went down to 6.0
Kahealani: 1250 ml; PH in runoff: 6.3-6.4; gave it 500 ml more and PH went down to 5.5???? Gave her 250 ml more and PH went up to 5.7.

I’m basically going crazy, the PH is fluctuating back and forth and the plants are suffering.

WWI: 1liter; runoff 15%; PH in runoff: 5.8
WWII: 1 liter ml; PH in runoff 6.1-6.2

WWI shows major magnesium deficiency, several leaves are getting distorted.
several leaves on Eva shows a lot of small rusty color spots on the margins.
New leaves on all plants are light green with dark green margins.

Pictures: WWI, WWI, Eva rusty color spots on leaves

[At this point, if I were you, I would just flush your plants. Just water them and leave them alone.
I have been growing weed for 16 years and have never ONCE checked the pH balance and never had a plroblem with my plants.

I think a lot of people put too much emphasis on the pH and it is a VERY delicate system. Trying to increase and decrease is just going to mess the plant up. Its not getting a chance to adjust at all so it is basically stressing your plant out.

Stop feeding or trying to change the pH for an entire week and see what happens. The let the soil dry out some.

same problem again, now has Kahealani also brown rusty spots on several leaves.
I made water with full strength nutrients and a couple of drops of Super Thrive PH 6.2
I then watered Kahealani with 1750 ml water
I got less than 5% runoff with PH 5.8
so i gave her 250 ml more water and PH went down to 5.7
and I gave her 250 more but the PH went down to 5.5!!??!!
shouldn't the PH go up when PH added is 6.2?
I cant solve this problem and I cant keep flushing the plants all the time.
what is going on?[/quote]

I'm using coco not soil, but next time I'm going for soil for sure, there is so much problems with the coco and I'm going crazy.

Hey, haven't checked in for a while. Sucks to see things aren't going that great. Ever since I started to err on the side of caution with nutes, my plants have been perfect, take a look below(started flower three days ago). Sometimes burn will look like a calcium or magnesium deficiency but if that was the case due to ph lockout, you would have a nitrogen deficiency as well and the leaves would yellow between the veins. I don't see this in your pics. I think what you have is nute burn. It is way better to be nutrient deficient rather than burn. All those burned leaves are toast, they will never recover. I would do one more good flush and get all those full strength nutes out and then immediately give 1/2 strength dose and let them dry out for 2-3 days. I only water my plants every 3-4 days with 3/4 strength nutes AT MOST. So my two cents is flush, 1/2 strength, wait. Good luck.

Oh, and for ph, listen to Lacy. Trying to get it exact is for advanced growers. I just make sure what I put in is as close to 6.0 as I can get it, don't even really test runoff.

hey az..

i can't see your pictures... they won't expand for me

really need to see wide shots of your plants...
