If you're 2 weeks away from harvest make that your last nute feed. You wanna make sure you get all the nutes out before you harvest. If it was me I would try the bloom with a little extra and make it my last with nutes. Plants in flower have a hard time coming back from issues as all the energy is going to making bigger buds. If you find the nutes helped, I would let it go another week. Just keep an eye on the tricomes and the possible "bud rot" but I really don't think that's it. Could luck man, they do look pretty.
