PPFD Management -- Am I doing this right? :) (See fan leaf photos for curling)

Focus too much on any 1 area and you will overlook the other 8. All 9 cardinal rules of plant growth must run in perfect balance. If any 1 single rule is working at 10% efficiency then it all runs at the10% bottleneck. Cannabis is a "weed" until it flowers. It will grow in almost any condition. What we aim for is optimal conditions for photosynthesis and equilibrium across the board. Light saturation is not the only determining factor in photosynthesis throughput. Temperature or LST leaf surface temperature, studies have shown optimal photosynthesis occurs at 86-87. But be careful as trichomes degrade at 87 and above. Also to note terpenes and flavinoids will start to degrade above 67 so keep that in mind after ripening stage. I personally run ambient 84 with lights on get it as close to your plants until top of canopy sits around 86. Leaf structure and formation look crisp and clean, colors look nice. Try hitting the sweetspot for her Temps, screw manufacturers recommended they just wanna cover their asses from liability. Most distance measures for lights are based off of hid with most guides telling you 77 is best but that's playing it safe. The plant is not here for a long time but she does want a good time. Warm her up and watch those droopy depressed leaves dance. Increase air circulation if you can, extra heat will really push up perspiration, increase water as needed.
