If the swing raises above 6.5 then I would personally put in ph down to correct it back in range. I only switch res 1x through my grow though, that is before transitioning to flower.

@Mr_Weeds_Autos I’ve always been told adding more ph down is worse for the plant than waiting the extra couple of days 🤔 They don’t seem to have any deficiencies and growing perfectly but personally I’d like to change myself just seeing what people’s thoughts are

I would adjust it when you notice it so you're always in the correct ph range for the plant to properly intake nutrients.

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
