Newbie with a problem...please advise

Hi everyone. Started my plants about three weeks ago. Looked beautiful and grew quickly for about two weeks. Then I started noticing a purplish shade on some (mostly bottom fan leaves) that turned into a copperish color and then leaves started turning yellow on bottom and moving it's way up. Growth has all but stopped. Any idea what this could be? I will say I'm using miracle grow soil. Also I believe my ph was off before...maybe too high. I've got a pH meter now and my run off is at 6.3. I haven't started any nutes. I'm using 600 watt LED about 18 inches away on a 18-6. I'll take any help. Thx!

over watering?

I second that.

Thanks for the idea. I wouldn't think overwatering because they were pretty dry each time I watered. Ive only watered about 3-4 times. Could I be putting to much water at the time and then it stays too wet for too long?

Ok I'll start off decent. Do Not use miracle grow soil for cannabis... Especially for young ones like that. Even Fox Farm ocean forest is too hot for a plant that size. Happy Frog soil is less hot. I can use it with newly rooted clones no prob.

Shitty drainage will cause overwatering symptoms even if you’re not watering a lot. I had that problem with my first batch of seedlings that I started in shitty soil earlier this year. Also, some were in a weird position on the tray, so they’d basically sit in water that drained out of the containers.

Looked a lot like yours — sad, curled leaves, discoloration, stunting. Please note that your soil appears to have zero perlite and just looks really heavy. I just chalked up my misadventure to experience, threw out the stunted ones and started a new batch. In my experience, once they’re stunted, they stay stunted.

Buy from a dispensary instead?
