damn man take it easy with the hard shit, i use to blow pills in highschool but i realized its soooo bad for you so i only smoke weed now.i think it was the bulbs and the adadpters ....got them from ebay...first time i turned them on..only half would light up,then after about an hour the whole thing would light up...then kinda pulsed a bit...and also i think it was the y adapters i was using..cheap ones i ordered from hong kong..was 2 bucks shipping and all.never had heat issues till i started using those bulbs and those adapters...but hell..if you spent 12 hours working on something that backfired and royally fucked your plants up..you would be pissed too...and ive still got 3 other strains just waiting to get going...i almost chopped the diesel ryder just to make room for the papaya.and i havvent slept in 2 days now..and was on viks and xanax..not a good combo when not sleeping
i hope the rest of your plants do better.
