Noooooooooooooo. Don't feed your SOIL plants using a ph of 5.6. A ph of 5.6 is for hydroponics not soil. A ph of 6.6 is ok for soil. What is your ppm when you water your babies? Your ph in soil should be between 6.5 to 7.0. Keep up the good work.
i'm sorry wrong for soil, but defo leave out the nutes for now that soil would be fine for a bit just water and i see he added a chunk of lime. test the run off.
