QB in Veg.. LIke they are starving >?

So i started swapping over to QB for Veg and all my clones and seedlings are yellowing up.
It is weird i even took plants that where yellow stuck them under t5's and over a week they got green again.

Anyone else have to change up there feeding schedule for LEDS in veg ?
This is new to me im already giving these things 600ppms.

Both 4k qb120 and 3.5k lighting Qb 132.


Im only running like 250 watts over a 3x3.
Is it just toooo much light ?

Could be too much light. But at the same time more light equals more photosynthesis equals more food.

I ran 260w kits over 2x4s and that was in flower and I still had to keep them 18" away.
I would of thought 10w per square foot would be ok for small clones and new seedlings.

you shouldnt be giving clones and seeds 600PPMs, it might be toxicity, or lack of oxygen

Unless it's a extreme heavy feeding strain that too much light and feed, you could flower a scrog at that level.

Ill try and tone down the light. Typically the strain i grow has no issues with 600ppm for established clones.

Thanks.

yeahhhhh i totally agree with inthevalley, too much food and or lack of oxygen.

If ur running 250w over seedlings & ur not 3-4' away then uve got to much light.

I had a similar issue when I switched my veg lights to LED. What solved it for me was upping my Calcium Nitrate and upping the air temperature to at least 80F. Everything has that slight gloss of green perfection again.
