Been using GPM for a few weeks now in two different systems. It seems to be causing extreme PH drops. Even after correcting the PH continues to drop every day. Don't know if this is normal or if it is reacting with my base feed, Floriculture Yellow bottle Bloom nutrients 2 part. Anyone else use Massive and or Yellow bottle base? Strangely GPM did not seem to cause problems at the first inclusion at 14 days into flower but on the second res change at 4 weeks the PH is dropping like a stone. No root problems.
Wilma system 60/40 pebbles coco, ec @ 4 weeks into flower 1.8. Feeding for 15 mins twice each day. 200 litre system.
