Cal Mag deficiency in organic soil
I need some Help. I’m a first time Grower. I’m growing in a 5×5 tent with a 600w MH, 28 in above. I wanted to make my soil. So I started in peat cubes and Transferred into
Pro mix hp, worm casting, small amount of compost and manure, Dr. Earth 4-4-4.
I was watering with bottled spring water but I’m using RO now. I’m watering in at a PH from 6.3 to 6.8
I’m in the 2nd or 3rd week of Veg. Acouple of my Gelatos were looking very bad, so I topped dressed with a Very small amount of Roots organic Elemental. They showed improvement. So I did a EZ Tea Veg Compost tea, and all the Plants responded within a Few hours.
But I’m now seeing the little rust spots on the lower leafs on all plants…how the first bad Gelatos started.
I plan on transplanting soon, so the soil mix I plan one using is
Pro mix, wormcastings, Dr. Earth Compost, Roots Organic Grow and Foundation dry Amendment. And I sprinkled in a small amount of Elemental. Less than half of what they recommend on the bag. And I was going to let it sit for a week. Is that good?
Please help and I really preciate it
