Ok this is my second grow and my lower leaves keep getting weird. I cleaned the water reservoir and my sensors. Im thinking it’s giving too much of one of the nutrients. I use distilled/RO water. TIA

Do you have a ec and ph meter to double check the water measurements? If so what are the reading?
And I will submit a ticket as well

Your top grow seems to be doing well, remove the affected leaves and watch for the problem to see if it starts to spread, sometimes ph can be off but if you start to adjust it now it could cause another fluctuation that may already have been corrected.

I do not but will b picking one up. But I don’t know what this recipe calls for as far as ideal PH…

So it started doin the same on the first set of leaves, once there was enough fresh growth, I clipped the first 2 leaves that were “infected”. Everything was looking good but I noticed 2dys ago the lowest 2 leaves are now doin the same…

Submit a ticket for a ph adjustment asap!
Looks a bit like calcium deficiency.
Have you checked all your hoses to make sure there are no kinks or stuck/ closed lines?
Did you choose the correct recipe?
I trust you have checked to make sure your air pump and air stone were working properly and bottom fan Is on.

Cut off the damaged leaf and the new one will grow

She’s adjusting to her environment and needs time. Stay on top of your drain/fills and she’ll be good to go by late veg-
