Louderanswered grow question 4 years ago Coco needs water daily. Don't let it get dry or the salts will accumulate at the bottom of the pot. Make sure you're getting 10-20% run-off every time you water. Flush it with pH'd water, mix a new batch of nutes and top it up. If you have a PPM reader, try measuring the run-off and see if the nutrients are being absorbed (lower ppm # than the inflow). If the number is higher than what you put in, there's likely a lockout or salt buildup happening
