My babies are in their 2nd week of flower, theyu are about 4 1/2 feet tall in FFOF soil in 5 gal buckets with proper drainage, ph has always been around 6.0-6.5. I fed them yesterday with 800-900ppm of GH flower nutes 0-10-10 and some 4-5-7, today i fed them with just plain water with no nutes added, i PPM'd the water that came out of the bottom today and the ppm was 250, are they underfed or overfed? They are quite big so im thinking it could be over feeding, bu tim not sure if its underfeeding or not. They did look slightly stonger up top after the feeding yesterday but down low they looked a bit more yellow. HELP PLEASE!!!!!!!! im desperate!!
