These plants are 1 and a half feet under a 400w HPS light. Theye have been in 12/12 cycle for 5 days. The room is 80 degrees, soil is 6.8pH and the soil (according to the meter is slightly moist) They received their first ferts last wednesday. I gave them tigerbloom but only at 25% strength.

The first plant, she doesn't have any yellowing but her bottom half is limp. Her leaves lay at her sides. In the morning when the lights first come on, they are not like that but within an hour they go limp. The top half is perky though.

The second plant, her new growth was yellow. I was told it was because she was overfertilized. But now her bottom fan leaves are turning yellow and working their way up. So does it mean she is still overfertilized?
