I have a blue MH 400W in a cool tube. But I tried to recycle some soil from 6months ago Ocean Forest that i sprouted a few plants in back then, I pulled them b/c instinct told me too Gfriend problems. So I stored the soil in pots on the balcony for a while now the PH is around 8-9. So This is what I did. i flushed every pot with 2.0PH H20. This brought it between six & seven(I broke my dig PH tester today trying to check the run off ph. so im useing one of those shity meters for soil. I foliar feed with fox farm grow big 5ml/gl every day so maybe thats why there looking better. Don't EVER TRY TO RECYCLE SOIL!!!@!! spend the money. If only I had bought fresh. Well there should be an Auto White Russian in coco/castings/perlite 60/35/5 ratio, self mixed and it is doing fantastic for a sprout. Is there a soil ammendment or a product other than just acid H20 that I can use to lower ph @ this stage in the game?
