I'm not too sure a couple of them still look to be a little sick but the other look like they are bouncing back. I will post some more pictures today. Thank you, I believe it was a Mag deficiency

I'm about to do a watering, feeding on some I will do a update with each plant. most look absolutely amazing, just a couple responded weird to last feeeding

The PH for runoff and for feeding always stays between 6.2 - 6.5, I use PH perfect nutrient line by AN but I still check for my logging. I checked the damaged leaves for any signs of pest and the grow room and other plants. No signs indicating pests. I'm concerned this is a toxicity or deficiency or maybe signs of both.

These plants are due for a feeding today, I'm waiting until later until it cools down a bit and I'm going to look at each one and do a separate feeding for each. That is what I typically do

the only time my humidity drops below 30% or my temp. rises above 80 Fahrenheit is when I have to do work in the tent. Or if the humidifiers run out of water while I am asleep. I am running two humidifiers, I live in Las Vegas N.V. So it is very hot inside garage. 118 Fahrenheit, so the tents heat up fast. Currently for feedings and LST I take one plant out at a time and do the work inside the house.

4Wx4Lx9H 16 plants. Autoflower half 3 weeks (21 days) into veg and other half 4 weeks (28 days). Fox Farm ocean forest soil with a top layer of Happy Frog, all planted in 5 Gal. Potting buckets. All planted at seed. Air temp. Is consistently 66°F - 78°F. I’m using AN Sensi Grow A & B. with supplements being AN B-52 and Turantula currently. On the plants at 4 weeks I’m not feeding tarantula. plants at 3 weeks I was giving: BlueLab Pen 700PPM Scale (1800 PPM) 2ML per liter of A & B Sensi Grow 2ML per liter of B-52 2ML per liter of Tarantula plants at 4 weeks I was giving: BlueLab Pen 700PPM Scale (2200 PPM) 4ML per liter A & B Sensi Grow 2ML per liter of B-52 i feed the plants whenever the medium is completely dry. (using the lift method & checking top 2in of soil) I have been battling the RH% keeping it consistently at 30%-45% but it’s hard to increase. Also if the Humidifiers run out of water mid-night the humidy will drop to 20-25%.. I see no signs of pests. I keep a sanitary grow, this is operating inside a tent inside a closed garage. I’m running 2 portable AC units 3200 LED watts. 1x 2000 Watt LED Cob by Aglex 2 x 1200 watt LED Cob By Aglex PPM using blue lab pen on the 700PPM was 2200 PPM for the 4 weeks and 1800 PPM for the 3 weeks. I’ll have to check the strains showing signs but one of the strains showing signs is Girl Scout Cookies Auto. i have a water chiller for my DWC grow set at 64° but I’m not using that water I’m using reverse osmosis and the temperature is 78°. My water PH is always between 6.2 - 6.5 always used reverse osmosis. I have one 6" inline fan pumping air from top to bottom of grow space, I have another 6" inline circulating air. This is a closed circuit grow. I have two 9KBTU Air units pumping into the room one turns on automatically if the temperature rises above 76F. The other is running 24/7. I also have two caged fans by jardin 6" on the corners moving air. Next week I will be adding CO2 into the grow space. I'm using the same nutrients in my RDWC grown and am not experiencing any problems. nearly the same regiment, I go by the recommendations of AN for feedings.

Currently I’m letting the soil dry up a bit longer. I plan to just do a calmag feeding on ones showing issues
