Question about my seedlings

Hi All,

Quick questions about my seedlings. They are looking pretty good. Working on their second set of leaves and roots are almost to the point where I need to transplant out of cups to 2 gallon pots. I have 2 Blue Mystic, 1 White Rhino, 1 Blue Cheese, and 1 Wonder Woman, all feminized seeds. I PH adjust everything and use a soil mix consisting of: 50% Organic soil, 20% perlite, 20% coco, and 10% organic worm castings. I have only had to water them three times over the past 2 weeks. The second time I used 1 drop of superthrive and .5 ml of technaflora's ROOT99 (1/2 dose).

Questions:

1. The Wonder Woman's first set of leaves (not cotyledons) are turning a purpleish color underneath. I have read that stems can get purple.. but is it alright if leaves do? This early? It is only that strain. Plant looks great overall.

2. I only have 126 WATTS of 2700K CFLS right now. I plan on transplanting and putting them under a 400WATT EIKO 4000K MH BULB for a few weeks till flower. What harm have I done using 2700K for 2 weeks of veg on the seedlings? I can only pick these bulbs up in my area.

3. I also have a Hortilux EYE Enhanced Spectrum 400WATT HPS light I was planning on just using for seedlings. Should I skip out on the EIKO 4000K and just use the hortilux? I have read that MH bulbs should be 6500K for veg..?

Thanks so much for helping my long winded questions.

Lots of people grow using Hortilux Super HPS bulbs from start to finish, but since you already have the MH light, go with that for veg. 126W of CFL's is fine for seedlings, but you should break out the MH by week 3. Lastly, you may be getting purple leaves because of cold temps. Purple isn't always genetic.
