hi guys and gals I'm seeking your help once again on these 2 problems. this is my 1st time growing in hydroton. the system I'm using is similar to the air cube system where it floods my plants on a timer. I've currently just flipped to flower but noticed these 2 problems. I'm using fc4800 lights, my pH is 6.0 and my ppm is 1 8 and all the usual nutrients during a grow at half the reccomended doses I'm also running a sterile flood and drain system. my system floods every hour for 15mins and then every other hour it floods for 30mins .. I think the 1st problem is maybe down to my lights being to close to the plants in which I've just put them a lot higher to see if they pick up there colour. the 2nd problem is maybe magnesium deffinciany so I've added more cal mag and raised my ppm to 2.2. please if anyone has any advice on my problems or any tips and advice on running this system would be very much appreciated
