POP Quiz! What does this look like to you?

Would you say this looks like nute burn? The ppm is only at 385. The plant is well into veg stage and I just recently went up to 385 ppm from 300 ppm. Could be something else though..? I'd love you opinions, so we can figure this out. Thank you!

Ph is most likely your issue.
If your not over-feeding, and your room is not too hot, and you've got ventilation, then.
9 out ten times it's your Ph.

I keep the Ph right about 6.

I am growing in a water farm drip feeder. I have the water on a timer, 15 minutes each, 8 times a day.

I'm just using a color code Ph tester..maybe it's a little off?? I get RO water and it's usually right at 6.0 and I keep a close eye on it and adjust accordingly over the days.

Well the water drips from a ring with 6 evenly spaced out holes around the pot. I'm not exactly sure how much water gets moved over the course of a 15 minute watering.

Does this sound like enough watering to you..or maybe to little?

Two weeks ago I added an extra air intake which dropped the temps down to a resonable level. They now stay at about 80-82 degrees during the day. I also have the light about 12 inches from the tops of the plants. (I'm only working in a 4.5 foot high tent)

Seems like everything should be in order for the plants to flourish.

Look's like Magnesium deficiency to me - leaves curling up ("praying" for Mg), yellowish leaves, interveinal chlorosis while the veins remain green...but I'm no expert! ;-)

Well it may appear so..but I really don't see how. I add my nutes as is..

-Per 4 Galons
FloraGro - 12.5 ml
FloraMicro - 7.5 ml
FloraBloom - 2.5 ml
Floralicious Plus - 1 ml
FloraBlend -10 ml
Hygrozyme - 8 ml
ViaMag - 1/4 tsp of dissolvable crystals

Brings the ppm to right about 385

Considering I add the ViaMag to prevent Mg def. I don't see how that could be the problem..not to say it definetly isint..??

OK...
Well, in my opinion you're doing something that you're plant doesn't like.

Environment (temp, light, humidity) - seems to be good.
Water - using RO water, no problem here. Doesn't look like over/under watering or a water temp problem to me.
PH - maybe a little high, but should be OK if it's not fluxuating drastically.
PPM - seems reasonable.

So if all of your environmental factors are good, it's probably something you're adding to your reservoir in my opinion. I personally think you're over-nuting one of your elements, which may lockout another one. And I still think it's a problem in the Mg area (maybe too much Mg which can lockout Mn which can display similar symtoms to an Mg deficiency).

You should get PLENTY of Mg from your FloraGrow and FloraBloom. I'm not familiar with ViaMag (and couldn't find anything on the internet) but I don't think it's necessary to add any Mg with the GH products.

Regardless, I would find out what I was adding to the res that's causing the problem. This is what I would do:

1. Flush with water to dissolve any built-up salts.

and either:

2. Start with the base nutrients until your plant recovers (which it should) then add the supplements one at a time over a period of time.

or

2. Eliminate one of the supplements per res change until the problem goes away (I'd start with the ViaMag).

Again, I'm no expert, this is based on my own experience, research, and logic, so take it for what it's worth...:bigjoint:

Alright thank you for your time and advice. I am going to do what you said and just flush the system and put fresh base nutes in. Just the Gro, Micro, and Bloom. Then I am going to wait for the plant to recover and apply the additives one by one waiting a couple days inbetween each. Hopefully that will allow me to identify the problem.

Here are some updated pics from today, it appears the problem is getting worse..

I never used those nute you got though as seems they always have issues and I never have such a low ppm as foixfarm at that point ppm is around 1450 ppm and I keep my hydro grows close to 5.5 to max 5.8

Ouch! OK, to really understand what's going on here you need to use the GH nutrient calculator: http://www.genhydro.com/genhydro_US/floraseries_calculator.html

According to your last post, you use approximately the following amount of base nutes:

3ml/gal of Grow
2ml/gal of Micro
<1 ml gal of Bloom

These concentrations will give you approximately 5ppm of Mg to start with, which is very low, and throws off the concentrations of the other elements as well.

GH recommends a 1:1:1 ratio for veg (for good reason). For instance, if you were only using the base nutes I would go with a 3ml/3ml/3ml per gallon ratio for where you're at right now. This would put your ppm at 230 with your Mg at 15ppm and your other elements more in line with what MJ wants.

I think you need to back off the nutes until your plant recovers, thus the 230ppm recommendation.

I personally use GH and the Lucas formula (which doesn't even use the Grow part) in DWC and am having great success - not even a hint of nutrient problems.

Hope this helps!

The Lucas formula.

Use five ml of micro and ten ml of bloom per gallon. Sometimes have a little mg def but I've been throwing in about 5 ml of cal-mag and it clears it right up. Usually keep my ppm right around 350-400. I would flush with some clearex or something and then bring your ph down a little.
