pretty sure its not a big problem but curious if you have seen it before PICS

Im not too concerned as this condition is only on a couple of the leaves. Newest leaves seem fine. Just wondering what those pale green areas are caused by.

DWC, PH fine, 700 ppm, week into flowering

Thanks!

I had looked a number of picture of plants with nutrient deficiencies, but I did not see what I thought was a real good match to my leaves.

What are you suggesting?

I am using RO and or rain water, so I guess there could be a Cal Mag shortage, but I thought my GH nutes had that in them?

i had this problem recently- blistered leaves and pale new growth and corrected it(although a couple never came back). Its def caused from the ph not being on 6.5 and prob too high causing cal/mag and other def. Flush with 6.5 water , check runoff, water and water/nutes. In the meantime try a very diluted foliar feed with MGrow. Correct it soon bro or they will die or be severly stunted.
