Leaves on plant in hydro bubbler are droopy and curled downward towards center (lower leaves) Leaves are curled up at the tip. Upper and bud leaves. OK I have read on her from numerous people thats an over/under water issue but since in using a hydro cant be so thin is been suggested that its a dissolved oxygen issue and to use 3% hydrogen peroxide to solve it but i have mega and 3 air pumps putting massive air into the water. Now I think that the upper curling leaves is a little radiant heat stress off of the HID light and that the lower curling leaves are probably caused by the fact that the water tank temp is 76 Degrees and that might be to far above the 65 degree water temp required for the water to absorb the oxygen and transfer it to the roots. Any theories , opinions , comments. Trying to figure it out i just dont know.
