Hey y'all,
I have a 2x2x5 grow tent. I have a 300W LED grow light, air filter filter, exhaust fan and a fan to circulate air (that whole set up). I am growing four Indica plants in the tent (they're supposed to be "King Louis XIII" but the source was not so trustful). I was supposed to only grow three but was given four. My thoughts were throw the weakest one away at flowering or stick three or four CFLS during flowering if the LED is not enough for the four plants. When I first got the LED put it to close to the plants (14") and burned them a little. They recovered and like the light at 20" now. Some of the leaves on all the plants are getting yellow around the edges. The only thing that kind of sounds like it is Nitrogen Deficiency but there's so much info it’s easy to get lost. I flushed the plants with PH water only about 2 days ago and new growth is starting to be all green. ALSO all my stems are red/purple color. I have started using Cal-Mag for this grow because i thought it would stop it but it didnt. If I can get some notes on the plants it be great. I’ll answer any questions thank you.

I don't use LED lighting but your plants look light starved to me.

Thay seem to b stressed to me are u sure the ph is right ? I would ease up on the nutes a little as well. Good luck

Morning Seven, what kind of water are you using ? Another thing ,I know people got different ways to water an feed in coco, but I always let my pots get real light weight before I water or feed mine, I don't water every 2 days, but only when they need it.
How long have you had that cal-mag ?
Your supposed to start from the beginning with cal-mag, looks like several different types of deficiencies to me.I sure hope you get straightened out.

This is my first time, i thought i would try it. I will def look into it though. Thanks

I have a PH pen so im pretty sure its accurate. I try to keep it at 5.8 - 6.0 PH. I use half streangth nutes at the momemt but will cut back a little more to see if they improve. thank you!

I use the tap water from my sink. mix nutes and make sure the PH is good. Each plant seems to take about a 1/4 gallon of water.

You know, that's the way i watered it last grow and it seemed to do just fine until i started reading on how awful it was to do so ( i don't have anyone to really talk "shop" so forums is kinda were i get my good/bad info). But i might start that again since it seemed to work the first grow.

I started the second week with Cal-Mag. My hydro shop was all out and so i had to wait in the mail to get it. This is my first grow using it. Don't really know if its hurting or helping.

Ya i see the same thing. trying to slowly get them back up to being healthy. Thanks for taking the time to chime iin

Yeah Seven, your gonna need cal-mag, with coco, an using LED lights.
That's what I would try is let it dry out before watering -feeding, like your last time.
I know there is different ways to water, but you got to find out what works for you, it's all different. Good Luck an welcome to GWE.
Nebula has got the best information anywhere, about growing in coco, in some of her tutorials, read them when you get time.
