My First Grow..Sort of! Big Bazooka

Not a whole lot has changed since last week. The nugs are getting fatter, the smell is getting stronger and Im getting more and more impatient. 3 more weeks I keep telling myself. Started playing around with white balance settings and some different filter lenses for my phone, as well as a 20x macro lens. Wish it was just a bit more magnification, but was still able to get some cool trichome shots. There is some discoloration happening around the edges of the leaves, mostly the top ones, that I am not sure what is causing it. Im thinking it might have been nute burn so Ive backed off a bit more on the nutes to see if it makes a difference, but im also wondering if theres some salt uildup in the blocks due to them not fully saturating the bigger block when watering, due to the smaller block on top and not wanting to make a mess. There is also what looks like a lightening of the leaves directly under the light. They are still green, just not as dark as the leaves on the outer edges of the grow. The leaves have also started cupping up a bit so I backed off my light to 750W. Im thinking with my current setup 1000W at this stage is a bit too much. I plan on moving my light higher on the next grow but right now with how everything is hung it would be a PIA to try to move it higher so Im just going to leave it and turn it down a bit. I also noticed they are not drinking as much, remaining heavier and heavier each day at the same time which led me to watering later and later at night to compensate. I got to a point where I couldnt stay up any later to water them and they were still pretty heavy by 1am so I decided to try leaving one of them overnight without watering. It went through the extra night just fine so I did the same with all 4 on the next feeding. Unfortunately, my little fan below the canopy was pointed slightly toward one of the my cubes and it ended up drying out on me. Next day that one plant was droopy. It came back fine after watering, but within a couple days I noticed the white hairs were all turning red on the one plant that was underwatered. Im thinking the stress caused it to start ripening pre-maturely. Glad its only one but I just hope it continues to grow along with the rest. This is the reason Im building a self watering system using moisture sensors. It wont be ready in time for this grow, but the next one will be fully automated and I wont have this issue again. Overall though, very happy with how things are going. Already starting to think about what strain or strains I want to grow for my next run. If all goes well the next 3 weeks I should have enough bud to keep me going until the next harvest. Cant wait :)
