Good to hear the plants are recovering woody, sorry I didn't see this thread earlier, I would have offered this advice: when you are mixing up your
house and garden nutes you want to keep in mind the order you add things and when you pH balance. They have just released their own silica product that they claim should be treated as an additive and so should be put in after base nutrients, but with other silica products I would treat them like your cal/mag, and add it before base nutrients. The order directed by House & Garden nutrient calculator is to add cal/mag first (and silica if your not using
Amino Treatment), then add Aqua Flakes base A, wait 15 min, add Flakes B, then balance you pH to within 5.5-6.2. This is the last time you need to pH your solution. Add the rest of the additives depending on stage of growth as recommended and if you don't trust me, check your pH and it will be 5.8-5.9 every time. then water as needed. When I read the order you have been doing things, I thought maybe this would be the answer to using Aqua Flakes to its full potential. Good Luck, and Glad to hear you solved the problem already.
