I have a problem with my tomatoes (3-4') recently developing leaf and stem curl. I am using two different commercial hydroponic formulas from Hydrofarm. Both units are exhibiting the same symptoms.
The foliage seems to be shrinking. I have been battling whiteflys through the entire life cycle of these plants. They seem to be no worse than when I began but I can't seem to eliminate them.
I just checked my peas and they are beginning to curl also. The leaves are not curling so much as the entire stem seems to to be spiraling back onto itself.
My PH had dropped considerably so I disgarded all solutions and made up new rather than try to adjust.
Any help would be appreciated. I have about 60 plants and sure don't want to lose them now!
