To keep it simple: 5 seedlings 2 seem healthy, 3 are showing the same issue. What I'm concerned about is the yellowing and lack of growth of the true leaves on these three. All are growing in 100% coir under 100w equiv CFLs to start. I'll admit I may have over saturated the coir just after they popped the surface, but I've been leaving the lights on 24/7 with fan on high to attempt to dry it out faster. I have not introduced nutes to the coir at all at this point. Compared to the plant in the first picture, the three problem plants have much smaller true leaves, and they all are yellow or are yellowing. All 5 are starting their second set of true leaves, so I'd think they're progressing on about the same, but with different results. I've read through the nutrient and watering problem symptoms, but I'd like you all to take a look and let me know what you think before I act on anything that could make it worse. Are these signs of deficiencies, signs of overwatering, or something else? Thanks in advance. Any advise helps.
