Hey guys don't mean to be a problem but I am having a little trouble with my first grow in a long time. I am growing some seeds from a dro batch that went bad. I planted the seedlings in Fox farms ocean forest with a 30%mix of pearlite (which gave each seedling bad nute burn); I also putabout an inch of pearlite on the bottom of the solo cups to ensure better drainage. They’re in a bin that’s 14"L 14"H and 20"W. I multiplied LxW and got 2 SQ. feet. Their under 6 23watt 1600 lumens 5500k CFLS( which comes out to 138 watts, which meets the 50 watt per sq. feet ratio and9600 lumens and 38,500k). I used a sun reflector for a car windshield as the plants reflectors for the lights. The temp. (Which I am having problems with)gets up to around 90-95 in the day and 75-80 during the night. I am using a boxfan to suck out the heat but it does not seem to work to good in the middle of the day. Like I said my seedlings got a pretty good nute burn from the foxfarms soil but the rebounded and started to look real good and just overnight my babies started to get black all over the leave tips and they are starting to die. The plants are droopy and don’t seem to be growing too much, also the pearlite seems like its turning green like if it has algae. Can someone please help me out in this situation because I am confused and please tell me anything I am doing wrong? The seedlings are like 3 weeks old.. Thanks so much!

I was watering every 2 days and by then the soil would be dry so i started watering every day because every 2 days seemed it was to dried out. I think the heat has alot to do with it too thats why i have that fan sucking out the heat but it seemd it is not really working. I have about a week to go before we really cool down. Do you think i have enough lighting for now?

High ambient temps increase transpiration. Plant pulls more water than normal from the root zone.
Because its trying not to dry out. This can cause overfeeding.
Young plants have less resistence to harsh enviroment conditions. I'd first try to find a way to control temps.

Good luck :leaf:

First i want to give a big THANK YOU to everyone who has posted to help me out with this problem. I understand that drooping leaves can mean overwater but i confused on that part because i only water when my babies need it. I watered my babies last night around 6pm and when i woke up right now (9am) the solo cup is bone dry and their in need of water again. I really think whats happening is what Zoltan44 is talking about and their getting to much nutes. When you say by overwatering do you mean how often i water them or how much water i give them?? Now i got one of my babies leaves turning up like taco shells. SMH
