Hey guys, just posted this in the problems forum but thought you wonderful folk here might be able to offer me some (better) help too
Just finishing week 3 of flowering, all perlite hempy buckets, under a 600w hps.
Using FNB (tweaked Lucas formula) with PK13/14 and Rhizotonic sometimes
Is this a deficiency? Or is it a sign of over fert?
They heaviest feeders, have taken 950ppm, while the other 2 plants have been given 250-400ppm for the last 3 feedings as they were CLAWING on the new growth (sure over-fert)
Yet all the plants are affected by this, all seem to display it.
Cheers!
