A week ago my gals were very lively and happy. They were lushiously green and everything was grand. Then I saw some signs of spider mites and I went overboard. I foliar sprayed with neem and Safer's End all (http://www.saferbrand.com/store/garden-care/5102). I made the rookie mistake of foliar spraying under a 24 hr veg cycle. I now realize that water droplets can act like mini magnifying glasses and burn the leaves. Okay so the new growth should not be affected right? Wrong! the new growth is starting to show twisting which makes me think it is a nutrient deficiency or lockout. I think it is a phosphorus deficiency for the following reasons:
-Ph of all plants is from 5.8-6.7 so I doubt Phosphorus is getting locked out by ph.
-The petioles are purple
-leaves feel brittle to the touch
-The brown/yellow discoloration starts at the perimeter of the leaf blades and works its way towards the middle and the leaf claws up and falls off.
-The leaves start getting these discolorations towards the bottom of the plant and it works it's way towards the top which correct me if I'm wrong but that is the symptoms of a macro nutrient (NPK) deficiency.
-I don't think it's a fungus because the discolorations are symmetrical and the new growth is twisting.
My city tap water fluxuates between 5.4-7 and it is a PITA! I often have to use ph up and down from earth juice to get at 6.5. I hate adding stuff to the water that feeds my gals but it is necessary to avoid ph problems and I don't have enough cash for an RO machine. The temps. are 85F if I'm not paying attention during the heat of the day and the lowest I've seen is 62F.
