Hi
@SpinnerGrow! I'm just starting a coco run like you so I had to process a LOT of informations. Here's a summary for you : 1) pH should be between 5.5 and 6.3 Usually 5.8 during vegetative stage and 6.0 during flowering stage. 2) nutrients should be in every waterings, since the very beginning of the plant's life. 3) Container could be 2 to 3 times smaller than in soil. 4) ΕΈou should measure the drain pH and EC levels, and give your plant a good flush if the drain's EC is > 2.5. Hope this helps, keep us up-to-date and good luck with this coco run!
