I am currently in my second day of flowering and i had an issue w/ a high PPM previously before so i dropped it down to 950 (1300 before)(10/12/12). there's about a gallon left of the veg nutes so i will be converting it into flowering nutes within the next day or so. The issue was that ppm was too high and it did show signs of deficiency but, i thought that was related to the ppm. so i patiently waited for signs of improvements but, unfortunately they never came. i just need help identifying this deficiency and how would i go about curing because i already have magiCal in w/ the regular nutes?


thanks in advance PPP

Did the spots on the leafs start from the old leafs?

Or did they start from the new growth?

definitely the old growth. and it's seem to be spreading quickly i see early signs of it starting to reach the canopy.

I had the same problem, couldn't get it figured out. It looked more like CAL / Potassium deficiency at it's late stages. Check my other posts.

I think I was a lot later in the stages then you are though..
