Indoor Spectrum King closet case and cfl

So this week all seedlings were transplanted into either 1 or 2 gallon pots. The ones in the two gallon are the Ghost OG #2, the Melato, and the 2 hyer up plants that were germinated about 2or3 weeks before the rest of the seeds. I'm slowly continuing to add in more cfls as the plants get bigger and space out. I'm now up to 10x 23w cfls. I noticed that the hyer up plant that I haven't mulched with leaves or anything was showing signs of magnesium deficiency so I watered all the plants and sprayed the leaves with an Epsom mix of about 1tbsp per gal. Shes no longer showing signs of any deficiency but I'm going to keep an eye on her. Hopefully my two hyer up plants will be ready for bud in the next 2-3 weeks
