It's my first grow I was getting excited when my plants were looking good and growing at a fast rate for the first week, but of course the wheels turned quick. Now this week all my plants are dieing their shriveling up and one has brown spots from being to close to the light I'm guessing or the heat idk(temps around 77-85f and 33-55 humidity) which is not high at all, I lowered the plants from the light but nothing's working and the weird thing is my sprouts were stretching towards the LEDS so Im thinking its not the lights Is it my growing medium???(75%Mg perlite, 25% vermiculite) I heard micro grow is bad and contains chemicals so of course I flushed the fuck out of the perlite before I planted the seeds but even after my temps not being bad all I can think about is it has to be the miracle grow perlite Idk WHAT CAN THE PROBLEM BE!!!!!
