    Does anyone know what this is? A few leaves on a couple of my plants have these spots that showed up over night. There are no bugs, it doesn't appear to be mold and I can't figure it out. Any help will be appreciated.They're in hydro (ebb n flow), useless formula, week5 (could it be the MOAB 1/2 strength).Thanks

    Are the affected leaves the closest to the light?

    First check the ph and make sure your calibrated right then shoot us a pick of the whole plant.

    Ph is 5.9. Calibrated the meter before I tested last night.

    uuuuuuuug well hps pics kind of hard to read but lets check this. Can you get a ppm reading on your solution?? The spotting may be your running a little hot if your ph is right or you might be experienceing some salt build up in the solution. If the ppm readings check with the formula I would flush the hell out of em and see if it makes a differance.

    I'm guessing it's due to the MOAB and the solution being a little bit hot. Probably not a real issue to worry about. Top off with plain water to lower the concentration a little bit. Also check the pH. The MOAB can cause a little more pH swing than when running the formula without it. A small amount of damage to a few leaves won't be detrimental to the overall outcome of the grow. :redbong:

    Bet its P overdose. Did you drop the base nutrient 50% when adding the the moab?

    From THE MAN himself. I thought that it might be P overdose, but I wanted to see what others thought too before I told jr that it was. At first I thought Cal MAg issue, but thenn I learned he was in week 5 using the MOAB. :passsit:

    I used the gh at 50% and the moab at 1 tsp per 5 gallons.

    differant strains take the formula differant. Some will take the full blast and love it others seem to prefur a lesser dose.


    Just a matter of personal preferance but I always run the formula 20% light and usually have great results. If it were my grow I would do a flush and go lighter on the nutes.
