I mix up my nutrient weekly and never had a problem with it but I sometimes smell a mild sulpher smell.
When it goes cloudy afaik it's due to elements bonding together.
Are you mixing it thoroughly and in the right order?
Order? I mix the canna bio in 10L bottles. Flowering plants are getting BIOCANNA Bio Flores, bio boost, seaweed powder, and cal-mag. After mixing I Add PH up to bring it to 6.1. Vegging plants just get BIOCANNA Bio Vega, and seaweed PHed to 6.1. Plants are doing great. Just had a funny smell because I used some left from the last feed. Read this thread and got concerned I through acidified feed in my strewberry glue at week 7 of flower. The soil microbes might help buffer my mistake a bit. These plants have a super high metabolism. They are in 5 gallon fabric bags and the ones in late flower are now drinking 3.5L of feed water every other day. I alway probe the soil just to make sure they’ve drank up the last feed before I give them another.
