All growing well, plant 2 is now the smallest but looks good.
I tried adding some myochum to the buckets of plant 1 and 3, it crashed the ph in plant 1 within 24 hours, i added less to plant 3 just a few ml ph did not crash, but roots are very stained, not going to continue using it.
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 , itβs a great effort Iβm 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 )
