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

Sort of had the same type of problem starting off with seedlings. Come to find out a majority of the little brown spots came from nutrient burn after over feeding the plants with veg nutrients and using coast of Maine organic lobster compost plus organic worm castings.
New to growing as well and a majority of the problems that end up arising are just from over feeding while in veg. we cut back and used Ph balanced water for a little while and it did end up being the problem. After a few weeks we started to give them nutrients again while adding more worm castings and coast of Maine to the pots.
Try just watering with the Ph balanced water for a little bit and if possible there’s test kits out there for you to test the run off water that comes out from the bottom of your plants. If that doesn’t work they have the plant stress calculator on here so you can always try using that.
