help, plants are in a coma

[rustymetal]

My plants seem to be in a coma.

I am using fox farm soil, fox farm nutrients. About 200w of CFL lights in a Rubbermaid. Temp 66-76f, I have been watering ever 2 or 3 days.

They are 2 months old, new growth grows for a few days, and then has yellow necrosis dies, then starts growing again. As you can see from my gallery they started off nicely. I have tryed 2 weeks with nutes, and without and flushing. Nothing seems to change their grow pattern.

Can someone help?

What kind of space or cab are you growing in? What ventilation does it have? You say 66-76 degrees im assuming 76 day and 66 night is this correct? Also are you applying nutes above and beyond whats in soil? If so how much?

they need to be transplanted asap!!!

Party cups are good for about 2 weeks, after that your plants will start to rootbound.

plants are in 30gal Rubbermaid, 2 stacked on top of each other.
Has great ventilation a 9inc fan on the top side, and holes on the bottom.
yes low at night is 66f and peak during day is 76.

Started the nutes at half strength on the bottle at 3 weeks (time of the first picture). They didn't help and kept getting worse so gave them water for 2 weeks and tried full strength nutes. They did not change so they have been getting all water. Tried 1/2 strength nutes again last week (Dec 1.). No change.

1. WHAT S YOUR PH?
2. You need to cut that soil with perlite...looks like htere is no drainage and I bet there is a huge nute build up.
3. Even half strengvth is wayyyy too much. FF soils already have nutes in them for at least 2-3 weeks. PH'd Water ONLY.


Solution: transplant into better drainable soil and add no nutes and get your PH under control. I think your plants are burning in a bunch of salt that has been building up. Also remember don't water unless the cups feel really light almost as if no soil was in them. After they start to recover add a little epsom salt or cal mag but nothing more. I would not give them nutes until they are too big for those cups.

You need to get those plants out of those crappy plastic cups and into some proper plant pots with proper drainage holes and a fresh set of soil.

Then just feed them plain water and water them correctly.

It would help if you filled out the form too.

Yup you need a transplant asap and definitely some perlite so they can breathe....
