🌡️ Mid-Flower Heat Management — Should I Hold or Push PPM in DWC?

"Do you still push the feed harder if the plants look hungry?" No, do not push the feed harder if your plants look hungry. Instead, assess whether the appearance is a true nutrient deficiency or stress-induced "fatigue". It depends on what you mean by "running hot". Cannabis plants can handle up to 86°F so long as water doesn't run out. What you are looking for is making sure your water doesn't deviate from 68-72°F. If it does, oxygen will rapidly deplete, and then everything will creep up at once. First 4 weeks of flower, I find it's ok to crank the heat in short spells as buds are far more capable of handling high light and temps than leaves, just make sure once trichomes ramp up, that you keep it respectable if you can, or the high heat will accelerate the degradation of THC to CBN. Pushing ppm in a DWC pushes up EC. Not recommended for a plant that is potentially already having uptake problems. EC is directly linked to osmosis. If your EC is rising in a DWC system, it usually means the plant is consuming water faster than it is consuming the dissolved nutrient salts. High heat is not impossible, just narrows the margins for optimal, that's all. root temp is the critical factor.
