Kalianna we are harvesting mad pineapples at the moment and I've never seen a single one like that. I know you don't like irritating advice. But...LOL, I can't stress enough how strongly we believe in foliar feeding vermi-compost tea. We spray everything. Hell we spray each other. LOL It's a darn miracle. You can literally see how much your plants love an evening spray, by the next morning. The worms are fun too. I can't say the tea will prevent that particular issue but I would not be surprised. I can promise it will radically improve your plants and your soil (which is what we are really growing here in Puna). Fingers crossed that this is received well LOL. Good luck with it.
I wish you all the best.
