these are photoperiod plants about 1.5 months into veg I'm not really sure what's going on ):

purified bottled water and haven't added any fertilizers. I've adjusted pH 6.2 and added CalMag in a couple of waterings, I transplanted them about 2 weeks ago. 350–500 ml every 3 days (7L pots) The pots take a long time to lose weight and I'm not getting any runoff
