I have 2 plants in isolated separate 5g DWC buckets in a 3x3x6 tent. I'm running a 600w MH light in a 6 inch cool tube 24 hours at about 30 inches from tops of plants. Temps stay between 76 and 78 generally but never above 79. My humidity has been a struggle as I cant seem to get it anywhere above 35%. I have a 4 inch 200 cfm inline fan pulling air out of the tent at the top through a 4 inch carbon filter. I also have a 6 inch 390 cfm inline pulling outside air through ducting and the cool tube. This fan does not exhaust air from the tent but does keep the glass cool to the touch. My strains are: 1 White Cookies (WWxGSC) from Crop King Seeds which is at day 26 from sprout; 1 Pineapple Chunk from Barney's Farm which is at day 22 from sprout. Both feminized. I'm using GH Flora 3 part and GH Calimagic at between 300 and 350 PPM with RO water. Ph has been stable between 5.8 and 6.0. It tends to drift slowly to 6 over the course of a couple of days at which point I use GH PH Down and adjust back down to 5.8. They aren't drinking much at this stage, but I have committed to weekly reservoir changes instead of topping off as I have done in the past. Thus these plants have each had 3 res changes. The first res was just RO water and 100 PPM of CalMag at 5.8 ph. Second res, both had roots in water so they got same dose of CalMag plus 1/8 strength nutes which ended up being around 190 PPM each. They seemed not to like this as I got some burnt tips, so I diluted the nute solutions back down to around 130 PPM. They slowly got back on track but definently were a bit stunted. At the most recent res change (1/29), they both had lots of roots in the water, so i gave them full strength veg nutes and calmag which brings us to current readings between 300 and 350. Now I am seeing splotches on the older leaves which has gotten worse between yesterday and today. I plan to change the both reservoirs tomorrow but am wondering what I should do differently. Anyone have any suggestions or advice? I cant seem to find a diagnosis through my research that fits. The closest thing I could find was maybe spider mites, but I cant find any black specks on bottom of leaves. However, the leaves look similar to pictures of mite eaten leaves. I would greatly appreciate any help! The smaller plant is the Pineapple chunk and the slightly larger is the White cookies. Both are less than 4 inches tall but have 4 and 5 nodes respectively. The White cookies is definitely hurting more but both show similar symptoms.
Edit: Forgot to mention, the White Cookies was topped at 22 days
