I searched for threads related to problems after using Greencure as a preventive, prior to onset of PM, and didn't see any threads.
I'm a fairly new grower, I don't have experience with using this product before.
I'm growing in hydro, 5 gallon buckets, DWC. 6" net pots with hydroton. Lush, green growth so far. PPM's are about 800, plants are in veg. Humidity has been rising to and above 40%. I've been told an ounce of prevention...
I sprayed greencure at less than half strength on all plant surfaces, right at lights out. Left the fans on. The next morning nearly all leaf edges, new growth and old, top of the plant and bottom were yellow/rusted. The tips of the new growth seems dry and brittle. Other than the leaf tips, the plants seem healthy.
I changed the nutrient solution that day, and I didn't ph it on the way down the drain. One cause I've thought might be that the high ph solution got into the water and caused some burn. I wouldn't think that much solution could leach down through the hydroton and into the nutrients and affect the ph of 4 gallons of nutes. I didn't change the ppm's this week so I know that isn't the cause.
Should I do nothing and hope for the best? Should I use a product like Advanced Nutrients Revive as a foliar spray? Would some other foliar spray work to reverse this problem? I have a couple of pictures that I'll try to upload.
