<span class="link_user">@Bncgrower</span>, Here’s something Ai said, Potassium Lockout: Adding too much calcium or a Cal-Mag supplement can actually displace potassium on the coco’s cation exchange sites. Excess potassium is infamous for dropping root-zone pH Thank you for your kind words, I’ve also checked your grows out I will definitely go back over them and follow along anything new, Looks like we’ve been on here a while, old heads ?:+1:

<span class="link_user">@cultivars</span>, Thank you for your kind words! :pray::+1:

<span class="link_user">@Bncgrower</span>, yea sweet I’ve had the same issue with a plant in the past was only the one, buds were juicy covered in trichomes just wouldn’t take K from the roots she just ate the leaves. I also think it can be a calcium “toxicity” locking out Potassium maybe not for you you but I think I may have overdone the CalMag considering it’s in the base nutrients and additional in coco is a must but need to cut it out week 5-6 flower. Checked your grows all look beautiful I like your style :+1:

<span class="link_user">@PharmaZ</span>, The first thing I do is soak the coco in boiling water for about 4 hours; then I rinse it under running water until the EC is practically zero and let it drain thoroughly. Next, I prepare a buffering solution according to the Athena manual and let it buffer for 24 hours; then I mix a fresh solution and let it sit for another 12 hours. I’ve never had issues with calcium or magnesium deficiencies or toxicities. However, I only started doing this with my new grow cycle; in previous runs—including the batch where I ran into trouble—I followed the same process but used Advanced Nutrients. So, aside from the pH drop, it could well have been calcium toxicity, just as you suggested. Let&#039;s see how the next cycle goes; I hope to avoid the problems I had before. Thanks for stopping by and paying attention to these details—your grows look amazing, too. Congratulations on the quality of your work!
