Was feeding 2.5 2.5 1.2 per gal flora series with 2.5 calmag ph quickly dropped in run off to 4.7. Im guessing the florakleen had something to do with messing with the buffer. I thought the king tut looked droppy a few days after flush of couse i thought issue was maybe overwater. I skipped one water and over night all plants were much worse. Half the leaves on tut dried out and some on the alien tech. Read up and finally found someone mention to feed 1.3 to 1.5 gal per 5 gal in coco coir per event. I was feeding 1 gallon of water twice a day so went to 1.5 to 2 gal per event twice a day. Underwatering was the issue, cal mag in some, nutrient burn and ph. Ph going in at 6.0 coming out 4.7. I chopped the chem de la creme and the acid as they were not doing well or just stunted badly. Squanch Queen had a lot of calmag issues so added more. Eventually i ended up doing a 1/4 nute 2.5 calmag ro flush to get the ph of run off out of 4.7 range and eventually it has risen to 5.2 to 5.4 in time with .2 ec adjustments. Lots of problems. Have an ro buddy but am going to get a better system. Working on installing diy drain system.
