ok but....Its your temps man. 64 with the lights on? just way to cold in there. I'm sure that was your issue from the start. and still is, i bet your leaf temps are mid to high 50's
My temps are usually in the mid to upper 60’s in here. Humidity varies between 50-70% or so. As I mentioned I’m going to build a plastic sided tent to get things more stable.hmm. I'm speculating light stress and maybe heat issues on plant leaves. If you got one of those laser thermometers take temp of those leaves on tops. I've seen this before in plants with under developed root systems and not being able to handle light intensity in the beginning. get a par meter if possible and measure light levels on top of canopy. also don't like the 81.5 temps with humidity in low 30's. You setting up for failure and all sorts of problems
6.2 too low for soil, use 6.5My well water is around a 6.8 or higher if I don’t PH all my water. Honestly since growing on this water is new to me I’m just doing it because I thought I must. I figured those fancy ph-down products were just phosphoric acid solutions anyhow. It takes me about 4 TABLESPOONS of vinegar per 5-gallon bucket to get it to about 6.2. Seems like it’s a bad idea. Again, I need to do more testing of my soil runoff.
I’m using fabric sided smart pots and they dry out pretty fast so I don’t think I’m overwatering. I only water every 2-3 days and I usually stick my finger in the soil or lift the plant to see if it’s dry first.
You can kinda see it affecting several of the tips of leaves in the group pic. Oddly these problems of dropping leaves, the loss of dark green color near the leaf veins, and increased purpling and redness on leaf stems and stalks have all gotten worse under these industrial 5K led fixtures. I upgraded my veg area to them to save electricity and this way I was able to put both my hid ballasted lights into my flowering room. Something about these lights is either a little deficient or it’s putting an additional nutritional drain on the plant that I’m not compensating for.
^It’s over watered. And root zone is locking out causing deficiencies. Suggestion, to allow media to dry out. Also ph swings cause a lockout as there is a finite range for certain nutrient availability and plant uptake. Container size is also key, start small and up pot to avoid drowning the root zone. Few charts attached to help ya
ppm meter, 10 bucksI have no idea and I don’t even know how to find out.
It’s 1” pipe (which a pretty sturdy) and corner pieces. I’m not hanging anything off it. The lights are suspended from the ceiling. It’s just a frame for plastic sheeting.you can buy a grow tent on amazon for $100 or less for the size you want, building your own will be a waste imo, I tries it myself years ago with pvc and it didnt work well or last
