I bought some clones from a compassion centre a week ago. recently it's been 32c-38c in toronto. I'm getting an air conditioner in 2 days. They came in rockwool. I put them into bigger rockwool cubes, been feeding them water at 5.7-5.8 ph. the only additive is aqua marine seaweed 0-0-5 Now for the problem. some of the leaves are looking burned and are slowly turning light yellow to white on the tips. I'm using a 6400 kelvin veg light. the light is about 4 inches from the plants and not really giving off much heat. any idea what I'm doing wrong?
I assume they are rooted clones because you transplanted them...? If so, then its time to either get them into some soil or to start feeding them a well balanced liquid fertilizer. What you are seeing is the plant basically eating itself to provide nutrients for new growth. If you give them the right nutrients you should see them take off very quickly.
ok that sounds about right. I've got a buddy near the hydro store. I'll ask him to pick up some nutrients right now. So hopefully in the next 48 hours you will get a thank full pm from me....or possibly another question. thanks alot for your info. peace!

Yep...I'm sure he's right but over-watering is always something I point out, they can look kinda the same.
Anyway, I would say he's right. A picture would get you a for sure answer.
I'm leaving right now to get the nutrients. I explained the problem to the girl at the hydro centre. so she is giving me a bottle she thinks will work. I'll post what I got. I'm using rock wool and letting it wick. I've got rock wool cubes that are 4 inches high and about 1 inch of water in it. I thought if the rockwool isn't swimming in water, it wouldn't over water.
