hey there CheckTT, that's not the right way to measure out the doses of each of those feeds man, the best you can do is try volumetric, that's also easier to do so you'll save a lot of time. Measure after each stage but dont get too hung up on it, in hydro you need a lot of nutrients. Everything else looks perfect ! Hope this helps !

Leaves curl, become crispy and have weird colors I need help. I've not had this problem before. The leaves get crispy and have weird colors. However, the buds continue to develop as usual. What could it be? Not all plants are affected. But it spreads slowly.

Brown spots on older fan leaves Spotted some brown spots on 2 of the older fan leaves today. Any thoughts on what the issue may be? Does not rub off- was worried about rust at first. Some more info that could be helpful is that I am using RO water. Thinking about rasing the lights a little higher up too.
