Plant turning yellow. Other starting to. HELP!

What is going on with this 1 plant... hope to fix it and i really hope the others don't start doing the same. First time grower. New to all this. Please help! These were transplanted from 1gal bags to 5gal bags one month ago. I use oceanforest fox farms soil. I currently have not used any nutrients since transplant. I have the fox farms nutrient line up. They were doing terrible as i gave to much nutrients a while back. Then i flushed them. They were transplanted to these 5 gal pots and recovered. Now all the sudden i am seeing problems with one of them. I have cal mag to if i should try that.

the worst looking plant most likely has low ph in the soil and can’t uptake nutrients that are already in the soil. if you ph your runoff it’ll be way lower ph then ph going in. Try raising the ph using 7.5ph water or dolamite lime top dressed or mixed into water.

I have ph up. Should i mix that with water to get 7.5ph then water? Normally my water is a ph of 7.1 i will test the run off though is that what i need to do?

My other ones are starting to turn also and i am scared. They were suppose to go into bud. Now i am stuck.

Yeah give them 7.5 water for a while and check what ph comes out. Make sure the water has at least 120ppm dissolved solids. the best way to deal with issues is to stay calm and systematically rule out possible causes. can you give me a little bit more info about the water you use? do you use ph down? do you let soil get really dry before watering again? we can fix this don’t trip too hard homie

And as you do what has been suggested you might want to get your ladies up out of any standing water as always thank you for your time and the best of luck
