Man those plants look beautiful, I don't know if PE even really needs top dressing now, maybe just make her compost and vermicast tea and put some straw/hay mulch on the soil if it's gonna be really hot in the next month or so. It's easier to judge how much to feed if you can give liquid feed instead of top dressing but I'm sure you'll work something out.
GA is really starting to take off now, I think she was just like many other Dinafem seeds I've heard of that take a long time to get going. She looks much more sativa-like and will probably take a lot longer to flower than the PE. She will probably get much bigger than PE too, I think you should top dress her instead, I have a feeling she's getting hungrier and will want more food and room for roots soon.
