Turned light up to about 15000 Lux this week using up the rest of the K-L-N I had mixed, going to start light feeding of 1.5ml Foliage Pro on next watering & turning light up to 20000 Lux today.
Run off levels have gotten down to about within 100 ppm above the solution for most plants but now I'm getting some blotchy leaves, under fed or something else? currently ruining 2ml FP/1 ml PT prior to this 1.5/.5.
