droopy leaves purple stems???

So I've looked an looked didn't really wanna post a thread if I diidnt have to. But here I am. I gotta master kush clone jus one. Under 4 cfls. Around6800 lumens. But the problem I'm having is leaves always seen too droop and many of the stems esspcially on fan leaves are dark purple(pictures below). I thought I was over watering cuz it started when I trasplanted into mircal grow. I put it in the smallest plant container I could find. From plant that's now in my garden.(not weed garden) ima goin to switch to ocean forest. But I couldn't wait to trasplant. It couldn't hold itself up. I watered the shit outta it till water was dripping from the bottom. It looked hella droopy an hour after. So I held off on waterin till she was completly dry. It was startin to look better till I woke up today. Leaves were all droopin. I thought lack of water must b the reason so I watered it carefull not to over to it. Since I can always add more but can take it out. An she is lookin worse then ever. Idk wat the prob could b. I'm startin to think mayb I packed the soil too tight mayb..

Or the mircal grow doesn't drain properly. I really have no idea at this point. Help please!

Miracle Gro doesn't contain much perlite so that's probably your problem, not enough drainage/over watering.

That's wat I'm hopin. I don't think there enough oxygen when I water it. But then again can't the plant use the oxygen in the water(h20)? This my first grow inside that's way I'm startin slow. Outside weed grows well like a weed up here in norcal. Very hardy an will survive droughts with a large root system. But idk mayb jus the mircal grow is wats givin me a hard time ima try to get most of it off without destoryin the root ball when I trasplant.

ya when u mix ur soil up use some chunky perlite and some vermiculite! if u use soil fromm miricle grow use organic that way u can give full strenth when feeding! what are u using for nutes?

You should try repotting him in to a Airpot that would help also . and yea id say over watering bro
