Monster-Cropped Green Crack Clones

Switched to flower last week so this is day 7. Getting some stretch that I've been controlling with SCROG net and some super cropping. Plants still look great...nice green color. One in the back corner has a few leaves with discolored tips but it hasn't gotten any worse so I'm just going to keep an eye on it for now. I'm strongly considering going back to my HPS light because the LED just aren't keeping the tent warm enough. I was using a space heater to keep dark temps up but now it's running during the day as well. Also, my humidity has been a battle since putting in the LEDs. I was ok with it during veg but it's averaging about 55 humidity right now with lights on. Just too cold in the winter where I live. And in the summer I'm battling heat in the tent. Constant battle. I think I'll save the LEDs for summer and MH/HPS for winter.
