Leafs turning yellow help

[SUPimHINO]

Need help with my 2 week auto tangerine leafs turning yellow

Here's some pictures to help

 

[im4satori]

Epsom salt

1/2 tsp top dress and spray 2x 3 days apart with 1/4 tsp per gallon

consider calmag 4mls per gallon and 1/4 tsp Epsom salt weekly

 

[Johnei]

What soil are you using? What nutrients are you using? How much nutrients have you been feeding? and on what kind of feeding schedule?

Need more info.
but overall, with absolutely no info,
I would go with what Satori said, best educated guess with absolutely no info just looking at the pics they need Mg.
or you have been overwatering on and off and is just not apparent in the photos this moment.

that sounds like too much man

might be way to much

tell me the 3 npk numbers on the two bottles

Grow big is 6-4-4 and big bloom is 0-0.5-0.7

 

[im4satori]

Grow big is 6-4-4 and big bloom is 0-0.5-0.7

3 tsp... that's 15mls per 1 gallon

that's a huge amount

a full strength dose for an established plant 12" to 16" tall would be 7.5mls per gallon

id pump a bunch or clean water thru it to get out some of that fertilizer you just over dosed

Hey man after reading this I rush to it and didn't see any burns yet watered on Friday picture taken on Sunday

 

[im4satori]

they don't look over fed so you might be fine

 

[Johnei]

Perhaps all the nutrient salts you fed, even though feeding at proper pH, has driven the pH in the medium down acidic out of range, and now you have Mg deficiency. Just a guess. I don't know.

Foliar spraying is best delivery in this situation if what I say is correct.
