Yellowing leaves mid flower?

I’m growing in a mix of soil Peat moss worm casting feeding advance connoisseur can’t figure out what’s going on here 2 different strains same issues

Would you be able to give us a breakdown of what you got going on in the grow so that when the more experienced growers come through they'll be able to give a more accurate solution for your needs?
Lights,PH,strains, all that jazz Etc...let's get the ball rollin!
might not even be too serious IMO noob here though.

Wish you the best fellow grower!

Looks like mild case of nute burn to me.

Tip burn is going to be from nutrients being a bit strong, likely unrelated to the current issue.

The mild yellowing or "lime" color is almost always caused by nitrogen deficiency in mid flower from the plant being hungry. I would try hitting it with some calmag supplement such as Botanicare CalMag+. I would run 5ml/gal of CalMag to fix an issue and then back it down to 2ml/gal unless you see issues, especially in flower you don't want your plant lacking Nitrogen as it can cause stunted growth and reduced yield.

CalMag supplements usually have nitrogen and also beneficial Calcium & Magnesium and with Botanicare you also get +Iron hence the "CalMag+". You should see results within a couple days of application.

Do you have any info on your waters PH or anything like that? Thank you.
