Hey bro, grow looks like its improved quite a bit since the last time I chimed in way back when this was still a micro hempy.
I spotted a couple minor issues that may improve things. One the lights, you could throw in a couple day lights in the cab
about 2-3 that spectrum will help if you still have the stretching issue. Second I dont think you have a def in nutes more
looks like a lock out or nute burn looking at how the ends curl over almost like a claw. Might be from a build up of salts.
Other than my two cents, I like the micro sog idea, im working on the bugs in mine. Just built another cab for mother, clones, and
a bit of vegging. I just have to get the timing down packed cause its way off at the moment.
I would post pic but they are too big, not sure how to resize at the moment.
