Not sure

anyone think they know what this is?

Strain : cannatonic
Temp : 72 off / 85 on
Light : blurple
Miracle gro soil
Plain tap water

Anyone ? I’m not worried, but I would like to know what it is because it is spreading. Also seems like they are not drinking, I watered 2 days ago when I took that picture and pots are still just as heavy.

It has a unique look that I guess is not seen often.
MG soils that have time release fertilizers for 3 or 6 months don't work well with cannabis, the others without the time release are probably OK but most growers would move up to something like fox farm ocean forest for better results.
It doesn't look like one of the usual deficiencies.
Nothing but water the whole time?

@Kushash I fed them once @1/4 strength at like 10 days old when they were in seed starter, so basically yeah just water. When I up potted to 4 gallon I used half MG seed starter and half MG moisture control, So the soil really shouldn’t be too hot.

This strain seems very sensitive compared to my last couple grows.

I’ll venture a guess that the potassium and phosphorus in the enriched soil are locking magnesium out. Try a foliar feeding with epsom salt. A tablespoon per gallon of water.

Ok, I’ll give that a try. Dumb question but is there a certain kind of epsom salt or is it all the same ?
