serious problem with flowering

dbo24242 · Apr 7, 2009

Hey everyone. Plant at one month of flowering now and it is having a serious pH / nute issue.

Pics help me out I have been told it is possibly NUTE BURN or pH is TOO LOW. Its a a soil grow.

The leaves are becoming covered in necrotic spots grey-brown in color and curling up at the tips before becoming necrotic themselves drying out and dying completely. I am losing a lot of leaves here. Please help!! I have all the micro and macro nutes supplied so is it burn or poisoning do you think? I plan on flushing the plant tomorrow.

Been fighting the same battle. Flushing well, then hitting it with 1/2 strength all-purpose, and a full strength bloom nute seems to have stopped mine from shedding and there's been no new yellowing. I'm thinking leftover salts might trigger this.
Molasses too early may contribute to low pH issue.

Thanks much! I recently started using molasses, I didn't realize it affects the pH much! Plus I was using a good amount of it (more than a tsp a gallon) so it was probably the problem. I flushed the plants that seemed to have recent issues or nute burn symptoms pretty thoroughly, and things haven't seemed to get worse thus far. Thx man

After doing some tests, it appears molasses is neutral, or just the slightest bit, like .1 acidic . . . so I wouldn't think it'd make much diff in this issue. I tested "lite" molasses.
