Hi all,

Thanks for taking the time to have look at my issues and any help or feedback would be appreciated.

SET UP:

Small 900mm x 600mm x 900mm DD90 Grow tent
1 x Duel spectrum 200watt CFL
1 x 4 inch extraction fan
2 x sensi skunk auto
OK soil with no perlite
Very cheap tomato nutrients minimum strength given every water, water, feed.
Moisture 45 - 50
Temps 75 to 80
Germinated 1st May

THE PLAN:

Im not looking for huge yields and just really wanting to learn the basics first. This grow was planned to be an outdoor green house grow but due to my climate limitations and fluctuations in day and night temperatures I decided to move them in doors after some reading.

THE PROBLEMS:

The first issues that were showing were the good old Taco on the top of the plant which I put down to the heat levels in my green house which on a warm day 90 degrees and in direct sunlight. This however only effected one plant. I moved the plant indoors in a hope that the taco would ease which it did not and at this point I thought I maybe had a PH issue.

So purchased a PH pen and before feeding them some tap water stand for 24hrs and checked the PH which was 7.2 so adjusted with PH down to 6.5. I then proceed to water both plants with this new PH water and it quickly went down hill from there. Both plants are showing brow crispy tips and brown on the edges of the leaf. Plus any new growth is a shiny green color and burnt crispy tips.

At this point I decided to flush both plants and check the run off PH which was 4.2 in the run off. Now i know from reading that PH run off is hard to get accurate due many circumstances. But even after flushing with many gallons of water the PH only went up to 5.1. So in my mind I thought it best not to PH the water from now on in a hope it would equalize some how. When flushing I also used the tomato feed in a very low dose to replace any nutes lost to the flushing.

WHAT TO DO NOW?

I think the mistakes that I made were the temps in the green house? adjusting the PH of water? No Perlite in the soil mix? and cheap tomato feed.

They are both in there final pots now and some of the new growth is looking better and really wanted to understand if removing the deadish leafs would benefit the plant? when should I start to feed again? and do you suggest anything else to help make them better :(

Thanks for any advice and help its much appreciated :)

I'm no pro but I would raise the light to 12", keep the same feed schedule but reduce nutes to half what you've been using and wait 7-10 days before doing anything else.

It's about 6 inches above them with a good breeze going over them. I'm concerned the heat stress started when I had them in the green house and become worsening due to ph in balance and nute burn ??
That's way too close, unless you're using CFLs. It's definitely a heat issue, though.

Thanks, I'm useing a 200 watt duel cfl which does run pretty warm. I purchased the cfl due to space limitations but think I should have went with with a 125 watt.
I think you should switch to COBs. I really don't think CFLs will yield much for you.

to me it looks like a nutrient problem cause the burn is on all leaves not just the top, also if the light was too close the top leaves would be much uglier then the rest of the plant... just what i think i see in the pictures.

keep the same feed schedule but reduce nutes to half what you've been using and wait 7-10 days before doing anything else.
this is great info and id do just that, cut the food in half and see if it improves in a week or two

Thanks Hexthat,

Please see the picture below of my set up, as I said earlier I went with CFL due to space limitations but the CFL I have kicks out a whole lot more power than the smaller ones.

Please let me know if there is anything I should add to the set up to ease with growth.

Thanks

if that's what you're planning on flowering in, i would suggest you ditch that CFL and get a T5. your girls are definitely suffering from too much heat from the CFL.

ETA: after you address this problem and they have time to recover from the heat stress - top them and keep an even & low canopy for flower

TBH I think the heat stress started when I had the plants in the green house with direct sun on them. Thanks for your advice and will look into the t5 at a later date.

water them with only plain water and add 1/2 tsp Epsom salt per gallon 1x

spray them with 1/4 tsp Epsom salt per gallon

then water in Epsom salt at 1/4 tsp per gallon 1x per week

only use plain water, add no nutes for now other than the Epsom salt

your height restrictions are going to be an issue ... space is short and plants will be tall

tell me about your fertilizer
what are you using and how much

Hi thanks for the reply,

I'm using typical garden compost whic is called evergreen in the uk and have just give them a little cheap tomato feed which has a very basic nutrient content. I used no perlite in the mix as well. I'm going to try and LST as much as I can to help deal with the height issues for this one and then buy seeds that better match the grow space.

do your nutes have npk % numbers listed on them?

are they liquid or dry salt?
, organic,?
time released, or water soluble

does it say/list what its derived from?

I suspect you are both over fertilizing and magnesium def

but we need to look at your fertilizers to figure it out for sure

the leaf damage you have will remain so we will need to look toward your new growth to see progress

eventually you will remove the ugly leaves but leave them on there for now since the still make speak to you
after your issues are resolved and you have some new growth you can slowly pluck the bad leaves (but not yet)

Thanks I really appreciate the help.

I am unable to post the link but the product is call levington tomato feed. I have used very little every water, water, feed. I think it all started when I had taco leaves due to the heat and direct sun in the green house.

I then ph my tap water to 6.5 which made it worse.

I'm going out tomorrow and buying some decent nutes.

did you guys even read the post? his problem started before he even put it under the CFL... WOW
Did you?
