In to deep to turn back

This is my first grow. I've done everything wrong, I've had root rot, gnats, nute burn, not enough light, wind burn, light burn, and heat stress, with temps well over 100 degs (F), what ever you can imagine has gone wrong. If anyone has any advise, I would really appreciate it. My big plants (lol) are 3 months old, the two small ones are almost 4 weeks old. The plant outside is a White Widow auto flower.
I put 3 of the 4 to flower at 12/12 last Sunday 7-23-17. I'm now using 400 total watts of cfl's. I've got an in line vent fan, an exhaust fan, and now I leave the doors open on the tent with an A/C blowing in it to keep my temp at 80* during lights on n 70* with lights off. My 2 older plants look pretty bad.

Read read read. Then start over. Most new growers make plenty of mistakes so don't beat yourself up over it.

Hey bud,

well, at least you went thru the pitfalls all at once. You sure you havent had PH problems yet, LOL..

Is your money Tight? Good to see you have a tent. Now you need a light. Those CFLs are crap, especially the way you have them set up. If your willing to use up 400Watts of Power, may aswell go big, right?

First off, Go to kindsoil.com and buy some soil. Then go to the local garden center, and get some FoxFarm Ocean Forest.

This is a Water only set-up. You put 1/4 of the size pot your using on the bottom with Kindsoil, then fill in the rest with FoxfarmOceanForest. Now, your soil is done. You just water every 3 days with RO bottled water. No PH, nothing to EVER worry about it.

Now, you need a light. No Mars BS. We want this to be super simple for you Buddy. This light is a simple 110 watt shop light LED style. almost 15,000, Lumens for $95 4000k spectrum, proven to grow nice buds. Its better then 4 Mars300 blurples.

Kindsoil-$28

This set-up will have you rocking and rollin, on the cheap side.
No PH Pen BS, No nutes to buy and meesure, SOOOO simple Man.

Im sure others have suggestions, but If i had to start alllll over again, this is the exact route I would take.

Good luck and welcome to Rooooliiiitttttuuppppp!!!
