Yellow leaves and new growth

[ThisGuy420]

I'm am thinking I have a cal and mag deficiency. The leaves and new growth are slight yellow and not really green. Can anyone shed some insight to this? First attempt to grow,...anything, ever. Using flora series and their recommended feeding schedule.

Looks hungry, I would up the N a bit and stick with the normal dose of calmag.

Looks hungry in general but not calcium or magnesium in particular

Think your light is to close or intense

Thanks, I have the light set at 30in from the top, its a 300w, led, no dimmer. I'll up the lights. What are your suggestions for height of the lights at this stage. There's 2.5 weeks old, from seeds.

If you have an android download light meter by my mobile tools dev and I would say 10-15k lux max. Increase 3-5k every few days to a week based on plant reaponse.

See how your leaves are cupping? Thats a sign they are getting a bit to much light

Still a bit yellow. I haven't been top feeding. Should I have been and if so, how often?

If roots are in the water your good. I top feed a cup or 2 a week just to keep any mineral buildup clear. Not a must but I consider it good practice

They're 5-6 weeks into veg. Why are the still so short? Any opinions and criticism are welcomed.
I just did water and nutes change today.
