OK peeps, I needs some help with my DWC. This is my first go at hydro, and have got the starts of calcium def, and it's already getting pretty bad. I think that this is due to pH levels. I have been running at around 5.9-6.1, but now dropped down to 5.6-5.7, hoping this sorts it. I have only been using BioGrow for nutes so far, apart from 2 days ago when I added some Hesi power zyme, which is micro elements, including Calcum. Think I should buy some cal/mag?
