Strange spots on bottom leaves pics...

strange spots have appeared could this be nute burn?

yes i would say nute burn. What are you feeding them and at what dosage ?

definately looks like nute burn!

i had the same on my white rhino and that was caused by overfeeding on the first feed. i reduced the feed as soon as i noticed it and now the plant is 100% healthy and new growth is appearing.

within a few days it returned to full health after reducing feed.

so i flushed the res and reduced the nutes and its still kinda getting worse should i just start feeding them water for now?? new growth seems ok though.

bump and im using gp nutients i dont have a ppm tester, but i used about 15 ml of bloom micro and grow for about 3 gallons.?......reduced it to 2.5ml after problem.
