Whole plant turning yellow and leaves turning brown and crispy (PICS)

drop ph 6.5, add N slowly. Flowering is going to take alot longer now

That exactly what I'm doing and it seems to slowly be working and the new girls I put in are now getting more N and they look great. I will keep you all posted.

Not enough nitrogen for that stage of growth i would recommend top feeding some mexican bat guano which is high in nitrogen but the damage done is there to stay.

Update: This was a Nitrogen Deficiency. I added Nitrogen and the new babies are doing great.PS once you have a nitrogen Dificiency the girls will get a bit better but not much.cut your losses.finish them up and fix the Deficiency from then on.Hope this helps anyone else who may be experiencing ng this problem.
