First Grow Attempt

Wrote my labeling of the strains on my paper towel when germinating the seeds, but the water made it fade, so not sure which is which but there should be a Gorilla Zkittlez from Barney Farms, and I think a Northern Lights & Amnesia Fast from Seedsman & a Red Diesel from Dinafem. One of them didn't germinate properly, which I think was either the Diesel or Amnesia, but I will just have to take a guess later. Will number the plants soon for the sake of clarity They were under a 75W CFL for the first week or two of life, but are under a 400W MH at the moment in a 4'x4'x6' Grow Tent. This is probably week 4 overall of life post-germination. I have a 400W HPS to switch to once I start flower. Temperatures are quite stable, at about 24C (75.2F) outside the tent, and about 28C (82.4F) in the tent under the lights, the top of the plants don't feel uncomfortable to the hand though Current soil is a generic general purpose potting mix for vegetables/flowers/fruit. One of the plants seems to have started to have some brown spots, light yellowing of 2 of the lower leaves & upward curling, which I understand may be a nutrient defficiency, so I moved them into some larger smart pots. Roots had started to reach through the bottom of the starter pots, so the timing seems good. I've made a soil mix out of the generic soil, coco coir & mulch, organic compost with a little bit of cow & sheep manure with some ground up egg shells mixed through. Applied some water with kelp extract to help with rooting & transplant stress I've mostly been feeding them plain tap water, but occassionally I feed them water with a kelp extract (maybe every 3 or 4 days), and I watered them once with a little neem oil to prevent pests, and plan to do so every few weeks or if I see any signs of pests showing up.
