White LSD Auto

When changing water I have been pumping used solution out of bucket, adding back dechlorinated tap water, and then adding nutrients and adjusting PH with up and down solution in the bucket roots and all. I have been adding frozen water bottles filled with solution to keep res water cool. I guess I’m in preflower/flower. Starting to see more and more pistols. I think I’m going to let them grow without tucking them into the scrog net. Water is going down, ppm is going up and ph is going down. There are rust spots on lots of leaves, assuming it is due to ph fluctuations or vpd being off. Adjusted humidity controller down to 45%… might need a bigger dehumidifier. Adjusted Temp controller down to 67F. Hard to keep tent warm enough for that humidity. Garage is cold right now. Temps outside are in the 20s. Update: 1/17/2022 the plants got too cold one night and started to look terrible. Leaves drooped and almost looked shriveled up. Should have gotten pics. Not sure if the heater gave out or what. I switched to 2 on the heater and it seems to be working again. My dehumidifier is useless. The next day the plants seemed happy again. Another cold front is coming in a couple days… Also I think that the rust spots were from being too humid for too long, and I read that it could spread. I picked a few afflicted leaves but it wasn’t too bad. Moved the light a little bit higher to maybe encourage more height in the colas. I wanna try mainlining the clone. I’ve already topped it once, just to control its height while I focus on the auto flower. Update: 1/19/2022 Plant bounced back from the cold. Heater seems to be doing a good job, but the dehumidifier is too small. Humidity is hovering around high 50s despite controller being set to 45, and the temp is staying close to 70F again. Gonna get cold again soon and test my equipment. I defoliated a bit more to get more light to the lower branches. Next time I’ll err on cutting the iffy lower branches before flower. Raised the light to about 12” above canopy, and backed off the nutrients, might back off more next rez change. Plant is drinking plenty of water. Ph is remaining a about 6.1, but the ppm is going up around 100 per day. Decided to keep the four branches on the 10th Planet. When they get a bit longer I’ll top those to get 8 branches, then I might scrog em, maybe top again. I spread the 4 branches out, was gonna hold them down with ties, but ended up just bending them. I wasn’t comfortable knuckling the plant yet, but I tried. I haven’t changed the rez solution for the clone yet. Probably need to, but it seems to be doing well, and I don’t wanna mess it up. Clone: drinking water, ph is stable at 6.0, ppm is staying right at 600. Looks healthy. Roots looks good(no slime.)
