I have began developing my own film at home, 4x5, in trays and been experiencing what seems to be uneven development but only in the skies. It may be in other areas but I cannot see it. It is very apparent in the skies. I presoak in water and constantly agitate in the developer. I am running out of ideas. Any input will be greatly appreciated!
I have attached an example. I brought down the highlights and raised the contrast to exaggerate the problem.

I posted it another forum and some have suggested chemical carryover, humidity, and blix problem. Wanna see if someone can provide more insight here.
Thanks!!
