150w + 150w metal halide . 50 cm above from this plant . but good reflected with aliminyum folyos :mrgreen: this is picture
and other plants autoflowered but looking good I think .they are at the 11th leave layer measuremetrei height is 30cm
because of nute burn I think . it seeems like too much nitrogen . I had same problem and stopped to giving them and it turned to normal . your plants colour is bluish green and this must be because of nitrogen
my formula is 100 ml water for 8lt pot every day . in the flowering stage 150 ml water every second day . letting soils surface to dry 3 4 cm deep . but dont well if it is right :)
