Hi guys. A couple of questions about LST: 1. Is it too late to start LST when the plant is already in flowering? Any downsides to this? 2. What if you have a CFL light bulbs set-up and you have light bulbs in each side of the plant and above it? Do you still need to LST or rather will you still...

Good afternoon, in your opinion is this excess light or just a pH problem? My lights are 4 x Cxb3590 at 55w each. I think the problem comes from the side of my ph meter since the lights are more than 50cm high EC : 0.9 / 1.0 Supplement Cal Mag
