Weedhound, what is really confusing me is that the soil runoff is 4.6-4.8. The ph of the typical solution I am putting in is around 6.0-6.1

The pics of the leaves are on my other post marked "Help needed fast" in this same thread.

I am definitely switching back to distilled water, and thanks for the suggestion. I used it before but then just started using my tap water I guess our of laziness and such.

Do you know why this problem would just now start to get bad? I mean, I noticed a few issues leading up to this point but it's gotten bad in just the past week or so and I'm in week 4 of flowering.
