I forgot to put the pH in my first post. It was 5.8 to 6.0
After i change out the (distilled) water and nutrients i have it at 6.25 now.
pH is checked 3 times a day and has never needed adjustment.
I increased it this time with the new water so i am not so close on the low end.
I only added half the nutrients so far. I sprayed the leaves down with water to wash fungicide 3 off. I also removed the leaves and branches that were effected with sterilized scissors.
Its 6 hours later and i am starting to see brown spots on a few leaves that were not there before.
