Hi. I grow with coco, flora flex 1.8ec b1/b2 0.3ec bulky b 21 12/12. What is it?

Hey buddy 👋 I’ll be honest with you, I haven’t grown in coco for a couple of years now, so take this as a humble opinion, not absolute truth. That said, from what I remember and from what I see in your photos, this looks more like a feeding / balance issue than a disease or pest. In coco, things happen fast. At EC 1.8 in flower, if runoff isn’t controlled or if calcium/magnesium uptake is slightly off, plants can start showing this lighter color and uneven growth even if everything else seems “okay.” From the pictures, I see: • Healthy structure • Active flowering • No obvious pest damage • Leaves looking a bit pale / hungry rather than sick I’d personally check: • Runoff EC & pH (very important in coco) • Calcium & magnesium availability • Whether the plants are being fed often enough (coco likes consistency) This doesn’t look like something dramatic, more like the plant telling you “I’m a bit out of balance”, not “I’m dying.” My suggestion would be: don’t make big swings. Adjust gently, observe for a few days, and let the plant answer you. Coco reacts quickly, so you’ll see changes fast if you’re going in the right direction. As always, this is just my humble opinion. Trust your observations, compare notes from other coco growers too, and let the plant teach you. Growers Love my friend and thanks for sharing the photos, they help a lot 🌱
