Bonus79 Had some leaf and root issues. Maybe I put too much stress by taking most of the fan leaves. I am running a Kratky hydroponic setup so I think I am going to add an air stone to the bucket to prevent bacteria/algae/fungus growth and add an additional fan up top. Fingers crossed, this doesn’t look good

Bonus79 Adding bubbles to the bucket and an additional fan in the tent seems to be keeping the plant alive. I started seeing some trichomes forming and the buds are fattening. We will see!

Bonus79 PH went up to 6.75 and TDS up to 1400s. There was only 1/3 bucket of solution so it may be concentrating. Starting to see the tips of leaves burn. Added 3 liters of fresh water to lower TDS but minimal effect on PH. Will change water to fix PH and TDS long term.

Bonus79 Everything went to shit this week. I didn’t do the water change last week like I should have. PH was 7.5 and PPM were 3500. Not sure how much of that is nutes and how much was plant matter. Either way, no bueno. Still alive though!

Bonus79 Finally changed out the lights from my home made fixture with 80% 6500k light and 20% 3000k light. Switched to a pair of 120w LED quantum boards. Each of the boards are loaded with 72 5000k, 176 3000k, 32 Red 660nm, 4 IR 730nm & 4 UV 395nm. I am running them on a meanwell 240w LED driver. It puts out a ton of light!! Did the final water change and the PH was 5 and PPM was 2500. Definitely not ideal but it looked like there was quite a bit of the roots sluffed off.
