They are growing well, had abit of what i think is salt build up in plant 1, so flush for 24 hrs.
Plant 2 is showing some deficiency going flush tomorrow for 24 hrs.
Plant 3 is a little behind but very large, i snapped a branch in pre flower which seemed to slow her down.
They do look lovely , now is about the time things can turn yellow , I think you have 2 weeks left , 3 if you want , you have passed all the crucial stages , now is just about finishing , I think they have taken longer because a) your led is 150 watt , b) lst makes it take longer , itโs a great effort Iโm suitably impressed , I wonder what you could achieve with a Spiderfarmer led .
Blue labs is a very good make , keep it clean with humidifier water ( 0-10 ppm )
