Does the nute solution come in contact with the foil? If aluminum is leaching, then you could have some potential issues.

i was struggling with that last week constantly trying to get it to stay at 5.5 and then after further research and reading the plants needs noticing that it really likes to stay between 6.0-6.2… guess that explains why the top growth seems much healthier than the bottom.

Great but looks like your tip is burning.
Do you track your ppms?

The plant is in 5gal Dwc.
I upped the nutes before I actually noticed them. I use lotus ‘grow’ and just added cal/mag to the mix @ 950ppm according to the feed chart at 3 weeks. I’ve seen posts saying it’s a cal mag def but not sure if that’s actually the problem. These spots anre only on the bottom annd there has been healthy growth since the problem started Any help would be great!

Did you get fertilizer feed on leaves? I've noticed a little on lower leaves in way when I feed my Ms. Blue DC Green.
