hi all, the seedling is about three weeks old, indoors. the first set of true leaves on both sides have stated to turn black starting from the tips. its in a soil mix i buy at a local store, i have never fed the plant, could it be a deficiency???

temps are naturally around in the low 90's where i live. i have it in a small box with a 35 cfm computer fan. When i water i get the whole pot wet, i wait untill it syarts dripping from the bottom, every other day. i dont have a ph tester, but maybe this afternoon i can get some from my brother who has some in his house, but hes a 1 hour train ride from here. i have 4 23w 2700K and 2 26w 6500K. i dont know if the soil is pre nuted ill check and post the info as soon as i get my ass off the chair!

dont water till the top 2 inches of soil feels dry when u put your finger in it. we need to know the temp inside your grow box itself, one pc fan probally wont cut it if ur temps naturally reach 90 degrees a day its gonna be hot as hell in there with all the lights going.

well, i think you may be overwatering. my big lesson from my last grow is to water less amounts, but more often. If you're completely soaking the pot ever other day, it's probably locked up from too much moisture. Plus the strange dirt thing.

If they're like the same stores in my area, there only gonna have Miracle Grow and maybe Shultz if you're lucky, but they're both made by the same company and neither are that great for marijuana. I ordered my mediums online, a 5kg bale of coco and jiffy peat plugs. If you don't have a hydro store anywhere close, it's pretty much buy online or settle for less.
