The problems along those lines (deficiencies/poor yield) that I have come from initial planting in the ppk from veg area. Great looking plants going into veg under CMH lights have come from poor initial watering technique. Now when a new plant goes in to the PPK, I take 1.5 gallons of juice at 600PPMs and dump it into the dry (ish) ppk. After all PPKs are ready, then let the PPKs drain back into the pump rez, let it settle a n hour or two and then top off (if necessary) the pump rez to control height 3 & 3/4". Then again I'm using turface and not coco: so? At one point, recently I adjusted PH before hand, it didnt work out so well and now have put the PH pen away. 600ppms (Jacks+) in RO gives me PH @ 4.8 going in and thats all she wrote, no PH checking. I dont recall ever checking the PH in the PPK rez after the grow but the PPM are in the 1K arena and they do well. Good luck.Very possible. Ive never ran the disolvine higher than 1g yet. I searched out haifa calnit when I started using jacks so is all I use. Due to the reasons stated.
My first run with her it came to mind that I was having lockouts due to high ec. In veg I flushed and lowered ec bellow 1.0 for periods to try and chase that theory to no avail
