I agree i added too much stuff, and for my next grow i will keep it simple. I thought by adding the stimulants and supplements it will make a healthier and stronger plant to help me through my first grow, but i did the opposite, lesson learned.
I was always worried about diseases, root fungus and all that stuff so i was hoping to protect them. And i was under the impression that organics wouldn't cause such issues, especially since it's all in the Biobizz range and it should work together. All this talk about ''impossible to burn with organic nutes'' and i fell for it lol..
However, i honestly don't think it's the BioHeaven or Alg-A-Mic causing the issue because i've used them on all the plants since seedling stage without issues. I was following an autoflower chart and diaries by some growers on the internet, many of them used the same supplements without issues. I think if seedlings can grow nicely with them, i suppose they wouldn't cause such damage now. And i never used a full dose, i always used very small amounts which would sometimes be quarter, third or half maximum, or sometimes i would skip it.
Neither the Plant Magic Granules seem like a big problem since it's only bacteria, fungi and root stimulants, and i've seen people adding tons of those during grows.
It all started when i used Fish Mix, it didn't look like a typical nitrogen burn, it just messed up the leaves the completely. And BioGrow also messed up the plant pretty quickly, again from very small amounts. I believe Fish Mix is 30% BioGrow or vice versa and it contains molasses.
The ActiVera i had was produced in 2020 and turned out to be rancid, smelled like alcohol and i talked to Biobizz and the seller, they confirmed it's bad, so i stopped using it immediately in the beginning.
But maybe my Fish Mix and BioGrow from 2021 could be rancid as well. After all i did buy them a year ago, and they last about 2 years. I kept them at room temperature so maybe they needed a fridge, and who knows how they've been kept in the store before i purchased them. And i don't have experience to tell by the smell if it's bad or not, honestly none of it smells pleasant to me.
Either that, or my water is too hard with too much calcium and locked out the K and magnesium, which i probably made even worse with those supplements causing a calcium toxicity.
For my next grow i'll be looking into some nutes made for hard water, i saw some 3 bottles in a package for a full grow with hard water.
And also, i stopped letting my water sit to dechlorinate, eventually i started using it immediately from the tap because i read so many times that chlorine doesn't harm the soil bacteria and it was more practical for me to fill the water when needed, but maybe it does harm the soil and kills everything.
And i also did a mistake by adding just water during the flowering stretch, because i thought i've been adding too much stuff. I should've started with Bloom nutes earlier. Now i'm not sure if it's a lockout or just very hungry.
Many possibilities to take into account and learn from, but most importantly as you said to keep it simple next time.
