Hello guys,

This is my first grow, and I'm making a lot of mistakes....
I'm growing a Northern Lights feminized (not auto) indoor, 150W.
I had leaf spots because I used to spray them with water during light periods, resolved.
Last week I made another mistake, I underwatered 1 of them, resolved.

But today I found some new spots on my leaves, maybe Calcium or Magnesium deficiency?





What do you guys think?
Can anybody help me out? Thanks a lot...

Peace.

Are you PH-ing your nutrients and flush? Soil? More info is much needed to diagnose your deficiencies. BUGS, have you looked? Most likely a deficiency.

Bottled water says a possible cal/mag issue. Like using an ro system. You need to add the calcium.and magnesium was filtered out.

Thank you for the reply.

HPS 150W. check the soils ph first and if that checks out then add a little mag and see if that helps if so problem solved if not add a little cal see what happens just be careful not to over add
