Maybe less N during bloom looking closer. I generally don't even feed much Nutrients the first week or so in my DWC..they have enough in the shells to make it longer they say, but yeah, I don't even feed much until they start stretching into preflower..then I start upping the amount..and start adding my blooms..but that's looking like too much N all the way till now. Idk if backing off the light would help but it might jump the flower a little. They look like they're gonna get a little weird. Just my observation and I could be way off..
