Hello, I’ve been successful so far with a Mephisto sour gummy bears grow with biotabs! They are in a 12l pot with biobizz light mix. I have 2 tabs in the pot. No other biotab additives, as I only had the tabs. Long story short, they are at day 40 with nice fat buds and dark leaves, slightly nute burned. I water with ro water and calmag at every watering. So far I have added coconut water, recharge and a small dose of build a bloom from build a soil and their big 6 micronutrient pack. Currently backing off adding anything else outside of water. As far as the calmag do you think I am overdoing it? Should I actually use it with every watering? I’m afraid of messing it up as I can see some light spots starting on some of the fan leaves. I’m only adding 1-2ml per 1.5l of water. And should I be adding anything else? Any advice would be great! TIA

Hi @Flyfish 
Welcome to AFNCal-Mag is the most overused cannabis additive and it will lock-out other nutrients. This topic is so common that I have decided to make a thread about it. Please read this:

Why are you watering with RO water? I think that practice is kinda debunked as far as organic growing is concerned, very dangerous to the overall mineral balance of the soil as naked water is an inherently powerful solvent that will want to bond to any minerals it comes in contact with, leaching them away from your medium.
