Over or under feeding or just plain killing it

Can anyone tell me what I am doing wrong I can't get this damn thing to stop turning yellow

What soil is it in? Have ya fed her? Tap water? Rain water?

It's in miracle grow soil and it gets rain water but when I give it water I give it tap water ph'd at 6.8 and I feed it fox farm big bloom nutes

You are using straight bloom nutes. Get some N for her. Get some grow big or other source for nitrogen.

I've never used bigbloom, It looks hungry, some strains are heavy feeders. I'd up the food and use calmag when you use rainwater.

I was using dyna grow bloom it is 3-12-6 and I also have foliage pro 9-3-6 which should I use with the fox farm or can I just throw some blood meal in that's all nitrogen I'm new here guys don't get frustrated with me lol

Are you feeding every time? Are you alternating water only- feed- water only - feed or what.? You are not really giving out much information, what kind of miracle grow soil? What dose are you feeding when you feed?

I feed water feed and I bought the soil do long ago I can't remember I give it full doses 4 tablespoons of fox farm to a gallon I pour about half a gallon at once

I think it's a 12 gallon pot I'm not sure
