Barneys farm pineapple chunk. 4 weeks into flower. Fox farms happy frog under a 400 watt hps light. Runoff ph is at 6.7. Temps range from 78 to 83. I am using the fox farm trio of nutes. The leaves are starting to either taco up or down. It started at the top, and is slowing working its way down.
Im thinking I need to flush with about 15 gallons of water then. Should I follow the flush with nutrients? And at what strength?
Hit her with 15 gallons of water ph'ed to 6.6 today. Should I wait a day or two before hitting her again with nutrients and at what strength would you recommend (if anybody is reading this)?
