Well it looks like a phosphorus deficiency is taking hold. 24hrs and its spreading. Flushed and fed with extra bloom for the P. New growth seems to be unaffected and caught in time. Took off the damaged leaves now that the new growth tips have enough foliage. Will watch closely and monitor ph. Sept.29- fed with ph 6.2 with nutes. Ph was getting a little low in run off at like 5.5. Soilless medium is a little tricky. Seems to be going alright since feeding more P. Will keep up a little higher ratio of bloom for this gal.. Oct.1 defoliated for light penetration and continued lst. Oct.2- watered and fed at 6.2-1 gallon with only maybe 5% runoff.
