I'm mostly an RDWC grower but am running some regular seeds I have in Promix.
In the past when I do this, I water the pots when they get light and dry with nutrients at a ppm level that would be suitable for DWC at each stage of growth. I understand Promix to be "nutrient-free" in a way, and like DWC, nutrients have to be constantly added.
My problem is that the plants in Promix are always much smaller than their DWC counterparts and show deficiencies, like yellowing leaves in flower, while the DWC plants grow happily with the same level of nutrients. They finish okay but there is no comparison with outdoor plants or the DWC ones.
I can't water more, as that would be detrimental, so should I add something to the Promix or increase the ppm of the water?
I know there are great soil recipe solutions but I really want to keep it as simple as possible and most like DWC. It is something I only do occasionally.
There are fertilizer sticks and additives. Would they help?
Appreciate your thoughts.
