I am new to gardening this is my first year. I am in Texas. I have had an awful time with my squash and I lost on eplant and the remaining one had mold and I removed all the leaves that were affected and it seems to be doing great and then yesterday I noticed several leaves had weird looks to the veins iand I don't know what this is. Can someone tell me?
They are fine on the back from what I can tell:
