You should be checking it every time you water in coco coir.
Med_in_Tropicanswered grow question 4 years ago
Check your strain first on how they takes fertilizers.
Usually an Indica feeds more, Sativa less, Auto is less. These days, most strains has mixed genetic. So it is best to see how other people were feeding the same strain with the same set up and environment.
Generally, week 3 would be a good start with 1/4 strength. It also depends on light hours and other factors that promotes plant up taking of nutes. Stronger and longer light hours.

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

Exit EC in peat and perliteVariety of opinions in the landscape with regard to watering to run-off when growing in peat or coco and perlite. Of course that makes testing exit EC a challenge. Asking for opinions - are the EC meters that have a probe to read substrate EC/salts any good? Is that the solution?
