Never had this before.

It looks like it's late into flower and close to finishing so I think if you just use 6.5 ph'd water until harvest you'll be golden. Almost time to start the fade anyway.

It has 3 weeks to go. By that time whole plant will be yellow. Iv searched everywhere for images of 'fade' and I couldn't find any that looked like this. It looks like something is spreading out from the veins.
