First time in flowering stage. I am running a hydr...

WhyNotA2started grow question 4 years ago

First time in flowering stage. I am running a hydroponics system.I have two ladies in flowering and I haven't given my plant any silica up to this point. Is this a mistake? If so, is it too late for the benefits of it? I have heard mixed results. Thanks

Not really a mistake because silica isn't needed, but it is beneficial in many ways. I started silica in flower when I introduced it into my feed schedule.. did I notice a difference? Hard to tell. I stop using it mid-late flower now mainly because I don't want to wait the 15 minutes for the silica to sit before mixing the other nutrients... it cuts my res change times drastically. Read the instructions on the bottle of how to use itand you will be golden. Good luck.

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?

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
