Does this look like a nute burn?

Dwc, 600W MH
46 days from seed
Ph 5.8, 280 ppm
Air temp between 27-30 C when light's on, 20 C and less when light's off
Water temp up to 21 C

Im using Aqua Vega A and B, some extra Magnesium and Calcium, Power Zyme

Ideas?

I had some instabilities with Ph and ppm in the beginning, I think the growth rate was suppressed because these anormalities. Also, I switched to MH just couple of days ago. Prior to that they were getting 8x23W CFL.

Even now I'm not sure if it's a burn or deficiency... my logic says it a deficiency. Should I up my ppm to 400?

Looks more of a def. 46 days they should be 2-4x that big.

Would you rise the ppm to 450?

450 is a good point.

1st time I used cal/mag my plants went crazy.....never really bothered checking ph in the past but when I did I found it was seriously low after the cal/mag addition.....if I were u id get ph under control & hook the cfl's up & save your mh for now, 8x23w are more than enuff to veg that plant for now !


This is maybe a month old from seed being vegged with only 2x13w & 1x26w cfl's.........
