First grow

4/7 week 6 day 1, it's been 35 days since sprout (went into soil 3/1 sprouted 3/3) overall plants are happy. Crystals are just beginning to form. The smaller one is finally taking up some water, but a very small amount for a plant this size, appx. 20oz every 48 hours. I oversaturated the soil with recharge in an attempt to get it going again and seems to have worked. I can tell this plant is root bound in the 3 gallon pot though. 4/8 got tired of fighting ph swings in the bases have switched back to top watering. Pulled side branches down one last time on the larger plant and they responded turning back up within a few hours. 4/10 the larger plant has some significant rust spotting. I don't believe it's fungus as the other plant is showing no signs, and it doesn't seem to rub off. I mixed up a new batch of water at 50% strength for everything except calmag at 100% hopefully this will correct the issue. 4/11 not sure if I have corrected the issue or not with the rust spotting it doesn't seem to be developing more spots but I am unsure. The plant that has been smaller this whole grow shot up in last 2 days and is now only 1" behind the other. This one went into flower a little later and it may surpass the larger plant. I measured runoff tonight and it was a 6.8 ph but the EC was reading close to 3 and the ppm was about 1500 feed water going in was .6ec and 350ppm so I suspect I have excess nutrients and needing a flush but I just water heavily with a calmag and recharge solution. 4/12 plants were 80% dry so I did another heavy watering of plain RO water pH to 6.45 runoff was still high near 1500ppm but EC went down a bit to closer to 2.
