Help with Green House mineral feeding

[solista]

Hello growers, greetings!
I´m running a Northern Ligths with Green House mineral feeding in a peat moss, perlite and a some worm castings and water PH @ 6.0.
I´m also feeding under the recommended dosage.
Many yellow leafs that I can´t identify the problem.
Any idea what it could be?
Thanks,
