ProfessorNusters811started grow question 4 years ago

Hi growers! Just wondering how much Calcium and Magnesium is needed per Litre? (Coco coir nutrients). My water is very hard and contains 117mg per Calcium Per L and 6.5mg Magnesium Per L. Should I be supplementing my autos with extra? Thanks in advance!

Hello community! I broke 2 branches this week. The first one happened by accident when I was draining the runoff, and the other when I was bending it.And today I came across a video where the author explains that silica can cause brittleness of branches. Does anyone have experience with silica and have you experienced anything like this? I add potassium silicate with each watering, at a concentration of 15ppm

Nutirents for hard water Question regarding the correct fertilizer amount. Advanced Nutrients. If my water already has a high EC of 0.75 I use less base fertilizer (Bloom A+B). But do I also reduce the amount of additives like Voodoo Juice and Sensizym, etc? Is there anyone here with experience with AN?
