Ever considered just doing coco or another hydro medium? All this organic stuff is way more confusing for me. I can use a meter and know exactly what I'm feeding if I'm questioning it I can run more nute solution thru the coco to get me set back right where I want it. I know some people are good at organics and swear it's easier, but how could it be easier than measuring out the exact amount of solution you need and adding it to the water, then use a meter to make sure it's right.
Glad to see your doing better with your plant. I too have hard time understanding why these lights seem to be easy to use for some and hard for others. I have been growing a long time and it gave me a lot of trouble. I work with a guy who runs his hlg at 75 degrees too, but he is way under powered like 250 watts in a 4x4. I think it's when you get real high intensity the issues start showing up if everything is not just right. Still don't really understand because with hid lights if you can keep your room cool it's hard to give the plants too much light. I've had up to 70+ watts per sq ft of hid without issue.
I still think the heat thing kinda makes the most sense, if you sit out in sun long enough even on 70 degree day your back starts to heat up, HID are the same way your hand will get warm if u leave it under there long enough. I don't believe LED light is that way, I sold mine or I'd hang it and check and see. I think it throws all that light down but the little bit if heat created goes to the heat sink then is radiated upwards. If leaves don't get warm enough they don't breath as much water out thus the plant drinks less which means it's uptaking less nutes.
As soon as I get my other flower room finished out I'm gonna buy the new growers choice 720 for my 5x5 tent and see if I can't figure out these LEDs. My thinking being I could use more lights and cool them with the same AC. Otherwise I'm gonna need 2 mini splits per room if I have to add more hid lights.
