Yellowing of leaves

My plants have now been in the grow tent for 6 weeks and all seemed to be going fine. There were funny signs of nutrient disorders or anything. I did add some Epson salt to the watering last week. I noticed some yellowing of the leaves again on some of the plants. What am looking at and what do I need to do if anything. Soil is soil I built up 30 days before planting consisting of potting and seedling soil, with general fertilizer, perlite, dolomitic lime, some epsom salts. Have enclosed some photos

hope this helps, I use it. To me it looks like a sulpher lock out

Hmm, not much as far as problem goes. Only a leaf set or 2. Don't see any mass or progressive problem.....
Water as normal and continue......(it's not S).
I would also say that you do not add Epsom directly to soil as an amendment....Dolo has PLENTY of Mg and Epsom is not good for direct soil amendment....You use Epsom by adding it in feed solutions at the rate of about 1tsp per gallon - NOT 1 TBL as I have repeatedly seen listed here.....

Lets keep an eye on your Mg level.
