New grow. Started seed in aerogarden until sprouted, then transferred to DWC. Will be on 12/12 lighting for a few weeks because it shares a tent with a photoperiod that will be done flowering soon. The humidity meter shows a high in the 80's because I used it to measure the humidity in my cloning enclosure. I should probably invest in another humidity meter. Anyways, I'll reset that so it's a bit more accurate.
I had a bit of a heat problem this week after increasing the lighting to 75%. A couple of leaves showed some signs of yellowing and shriveling, which may or may not be heat stress. I will try to decrease the temp in the tent to see if it helps. The dehumidifier was set too low and the low humidity might have caused some problems also. I will set it back to 50%-ish and see if it helps.
I was able to decrease the temperature in the tent by a little bit and the yellowing leaf problem stopped. The light is at 75% power and everything is looking good so far. I started a bit more aggressive LST-ing so we'll see how that works out next week. Added 1ml of calmag to the solution.
things are picking up, more preflowers are showing. did some lst and leaf tucking. Changed reservoir with some fresh ph'ed water and added some maxigro, maxibloom, and calmag.
After the main tip breaking off from LST and a few problems showing on the leaves, everything seems to have been fixed and growth is vigorous.
There seems to be a tiny bit of nutrient burn or something that is affecting some of the tips of the leaves, but none on the newer leaves.
