There really starting to grow fast and bushey now, slowly starting to introduce bloom nutes.
Plant 1 still looks a little pale, i kept nutes at 550 ppm, and topped up twice with just 2ml of grow nutes, she's looking better than last week, will be moving to 650 next week.
Plant 2 and 3 are smaller but look really healthy.
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 )
