Heat stress or Magnesium deficiency?


Well-Known Member
8 day old from sprout. At the advise of another member I did turn on and lower my 130wt LED ufo to about 22" above the plant. I also have a 60wt CFL (Hydroponic Full Spectrum CFL Grow Light Bulb 60 Watt Bulb 5500K H60) about 3 - 4 inches from the top of the plant.

I moved the CFL up a few inches, and raised the LED about a foot just in case.

I am using FoxFarm FX14053 12-Quart Ocean Forest Organic Potting Soil straight. Not mixed with anything and have not started nutrients yet.

On a side note, my other 8 day old in the same conditions doesn't appear to have the issue with the leaf curling up.

Temps have been 80 - 85 during the day with RH between 30-40%
at night they drop to 75 - 80.

Any advice?
