Hi FlowEst, your grow looks great. Well done! When I had issues like that it was PH related but it was early on in the grow. I would also guess at Calmag - but I'm not an expert by any means. Know LED can make it more hungry for it. Guess adding a bit of Calmag wont hurt any way - i double dosed by mistake 2 weeks ago when at 8 weeks in and it hasn't harmed them, got about a week to go now on my grow.What do you think? Im guessing lack of calmag.
