My guess is you have more than one thing going on.So I went out and bought pool testing strips. Unfourtunatly, the bottle only has the colors to match up for a PH of 6.2 and higher. So 7.5 was red, 6.2 was orange and the strip I tested ended up coming out yellow. So I'm guessing my PH is around 4.0 - 5.0. Should I adjust this so close to being done? If so, whats the safest way this far along in the game?
Some leaves will be yellowing because it's reached that part of it's cycle,
you definately have nute burn and possible pH issues, on top of that,
I would guess at overwatering too. judging by the shape of the leaves.
Unfortunately, flushing will make that worse but the leaves will pick up in a day or two. it is better to flush the nutes out that's what is doing the most harm.
Don't worry if all the leaves are yellow just keep an eye on the buds and trics.
Molasses would do them the world of good and it's cheap too, plus it will raise the pH for you a bit.
A few DROPS of lemon juice will bring it down.
Anyway Sorry to go on, I am growing G13s too and am in my 9th week of flowering. If you check out my journal (in signature) go back from the last page you will find pics of a G13, she's 9 weeks in and started yellowing in her 7th week of flowering.
