clones turning yellow then white

#571485 - 07/12/11 10:24 AM (13 years, 7 months ago)

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'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.
