So 1ml of each per litre of water will increase your ec by nearly 1.2

I think gro 1ml/L is ec 0.4 increase. Think micro is nearer ec 0.5 for 1ml/L and bloom is about ec 0.25 for 1ml/L

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?

Very abnormal EC Runoff for CoCo Coir - please help on what I should do. I am scared to increase nutes in case I get nute burn
My EC going in is just under 2,000 (The maximum it should be much later in flower according to online) but comes out much lower and is getting lower each (735,467,368 respectively). Online says that Coco runoff will always be higher t- what should I do? I am scared to increase

Anyone know about biobizz TopMax? (Just read this)

Composted soil and pH
I read that using composted soil you don't need to stress about pH too much. My water tank gives water at 7.7. Run-off is fairly similar. Should i be trying to adjust this down a little before watering?
