  1. Hello everyone. So I have an issue, cant tell if its nute burn, lockout, underfed, salt build up (soil), ph, deficiancy?
     
    4th week into flower, plants turned yellow, (nitrogen def/lockout?)
    Middle of leaves turning brown, brown spots in randow spots.
     
    The most affected plants were the ones closest to the lights but all turned yellow from the top to the middle, not the undergrowth.
     
    Are they starving? The runoff ppm was 1100, and I have yet to feed it that much in one feeding so are they not eating or overfed? ph 6.5.
     
     
    Is this nute burn? or a deficiany (cal/mag) or from lockout (overfed)? I know the plants are stressed, trying to resolve this problem. Any advice is appreciated!
    Thanks!
