temp in veg 75-85; humididty can bounce between 40-90; running t5
temp in flower 65-75; humidity 50-65; running 1000W
air flow is good
ph is checked at every feeding 6.1-6.5. runoff has been checked and is consistent. have tried flushing but with little improvement
the leaves start off sort of barely folding in at the edges, then they become an unhealthy pale color almost yellow/gray. usually it stops/recovers about half way down the canopy and generally once in flower it doesn't continue to wrinkle or turn leathery but the affected leaves then turn into claws. yield is definitely affected i feel. also, strangely it doesn't always hit every plant in the crop, though usually a majority. also oddly, it has never crossed into other strains though just today i noticed a Grape Ape mother starting to show the first signs.
any help would be greatly appreciated!!!! starting to feel a little crazy. happy to provide more info or photos! thanks!!
