Hi all, I've grown in soil for the last year and a half and now gone to RDCW.
I'm having a kinda surprise issue. Everything has gone very well until the water change.
My current setup:
UC Epicenter with 5 gal res. using tap water.
4 13gal buckets with air stone in each (~65 gal total system) ~900gph air.
Water chiller, 68 - 70 degrees F
Air Temps 75 - 80 degrees F
RH: 60-70%
pH 5.8 - 6.0
EC 0.2 - 0.3 (veg) - 0.5/0.6 (currently)
UC's nute schedule
4 Plants:
2 Cannatonic CBD
2 Sour Diesel
I was switching them to flower and did a majority water change(90%+) and added 300ml UC Roots then pH'd to 5.7. Water temp was ~74 and falling for about 4 hours after the water change.
24 hours later:
Added 120 ml Bloom A
Added 120 ml Bloom B
pH'd again to 5.7
Found pH to be 6.7 and one Cannatonic CBD to be fully wilted and the other mostly wilted.
The two Sour Diesel seem to be fine, though, maybe a little wilted.
Began bringing down the pH to 5.7 over a couple hours & added CalMagic. pH is now 5.7 in system and res is 5.8.
Roots (both Cannatonic CBD in pics): slightly yellow. The Sour Diesel roots look the same
Any help to save the CBD strains would be greatly appreciated.
