Hi all,
Its about wk 4 under CFL's and my baby is not looking happy.
Growing in soil, having been feeding only water for last week (ph adjusted)
Lower leaves turning yellow, and all tips curling down and turning brown.

How many lights do you have? If all you have are those two cfls, then I'd say that you don't have enough light. 3000-5000 lumens per square feet is recommended.

I see nutrient burn. I'd back off the fertilizer a bit.

Also, what is the pH of the soil, and what kind of soil are you growing in? Do you have a digital pH meter? Digital meters are the best. Other methods of testing pH seem to not work well for many people, including myself.

What kind of water are you using, and how often do you water it?
 
hi Alister

there are those 2 x 3800 and 2 x T5s on top

as per advice i got the ph tester kit but not the 150 pen

been giving 500ml every other day

am using a bonsai potting mix, the expanded clay is on top to keep the soil from drying out.

I have a feeling i probably overdid the trace element mix, I gave her a shower but is still looking stressed.
