Round 2 RDWC - West Coast O.G. FastBuds

4/13 - been rough and cannot seem to get dwc right. On this res change I sprinkled the root zone in the LECA with mycorrhizae and trichoderma after too feeding with hesienberg ewc tea. Then drained res and refilled with ~1/4 AN recommended and no cal mag as starting PPM is 140. Trying a RV water filter with carbon and 5 micron screen instead of bubbling buckets of water and using dechlorinator. Added another air pump and air hose diffusers for even more DO. Seeing new white roots, ordered some cannazym - maybe this is the missing part to feed the microbes and clean up some of the older roots. It almost looks like overwatering or K and N def…. PH and PPM and temp RH have been in check with no drastic swings. Can’t figure out what I’m doing wrong. Decreased light intensity to ~60% 4/18 - end of week 4 veg and into flower…think I’ll try photos next because this sucks. Cannot get them to grow right after like week 2-3. Added cannazym and little sponges/filter for the microbes to settle on while I brew more ewc tea. Then add that 1C/gal for 24hr then rez change and 1C/10 gal.
