jobes at 1/4 strength right? what kind of lights are you using? red/blue? red/blue white? cool white, soft white? they may want something a bit closer or more full spectrum... I might flush the soil as well.... how much Epsom are you using?

I'm using a 300 watt full spectrum led light. It has red blues and whites. It's actually a pretty intense light. I have a 400 watt hps I'll use to flower the master kush but I must admit the led light is a beast it is very bright so I know it's getting enough light. Not sure if 22 inches is to far but everywhere I've read it states 18 to 24 inch is best for veg than 12 to 16 inch when flowering . As for nutes I'm feeding it 1/4 strength of jobes organic granular 4-4-4. I'm wondering if I need to feed more or less. I feed every other watering which is about every 8 to 10 days or so. I have a soil moist meter to check when to water and I also check about 2 inches in soil to see if it's dry and I check the weight of each pot when dry and wet. I got my watering down so I know it's not that. Since I use ro water I been told to feed about 1 teaspoon of Epsom salt for every 1 gallon every other watering which I do. One thing that concerns me is I'm using mg organic soil mixed with mg perlite. The bag says the soil has I think only like 0.2 nitrogen and the perlite for some reason has like 0.15 nitrogen. I don't know why miracle blow always has to put something in their stuff but money was tight at the time so unfortunately got the mg organic. I'm wondering the mg is time released and every time I water nitrogen is released from the soil and the perlite. Not sure if that's how it works. Also was wondering if heat stress is a issue because sometimes it fluctuates from 75 to 85 degrees.My main concern is the slow growth and the yellow. I'm not sure if it's nitrogen toxicity or
Diefiency. Pardon my spelling lol. I'm blazed and predictive text is pissing me off so i turned it off. Anyways , I really want to help the master kush because I want to clone her as for the super skunk I think attitude seeds sent me a auto flower on accident. Any help would greatly be appreciated. I'm a newbie and I'm stressing over my babies. Thanks for your time.
