What are these signs?

[OM2]

Hi, could anyone please help me with diagnosis? What signs are these leaves showing?

- Autoflower in 15L pot
- 5 weeks old
- Biobizz Light Mix + Plant Magic Granules
- Watering every few days with 3L of tap water, pH 6.5 after adding nutrients
- So far i've been adding Root Juice, BioHeaven, Alg-A-Mic, Acti Vera 1ml/L of each. Also i'm adding Silica 0.1ml/L
- I also added 1ml/L of Fish Mix twice so far, with a long period in between. And in both cases the leaves looked like this right after. I think that Fish Mix is the culprit but i'm not completely sure.
- Temps are 27-28C during day, 22-23C at night. Humidity is always around 50-60%

The plant showed her first few pistils few days ago. I'm still in the process of LST, i'm waiting for the branches to stretch a bit to tie it down more. I also defoliated a lot because it's too compact and bushy.
In the picture she looks unhappy because the light just turned on and i haven't watered in few days. But usually she's perking up around the middle of the light schedule.

Should i start feeding Bloom nutrients? Maybe CalMag? It's hard for me to read the signs, it seems like many deficiencies combined, plus maybe nutrient burn, i can't tell for sure.. Let me know if you need more info, i appreciate the help!

I think you're right - to my eyes, the dark leaves look like an overdose of nitrogen, the froopyness looks a little overwatered and heavy.

I've used light mix for years - it's great and never has too much nutes in. You can use water only for 20-30 days.

I'd drop that big line of nutes and ammendments and stick to the basics. I think the EASIEST way to get good results with biobizz is to use Canna Vega during the veg cycle and Canna Flores during the flowering.

You don't really need Anything else.

I'm not sure how the granules work with the soil and plants as i don't have experienec with it. But i think keeping it simple to start and bui;ding up form there is the way forward .. too many additives mean you don't know what is causing what.

Hope this helps a bit

The more stuff you have in the mix, the more you gotta wade through figuring out what went wrong......when it inevitably does.....My best results so far have been RO water, MegaCrop, a pinch of epsom....

Thanks for your replies.
Next time i will only add water and nothing else. Definitely not Fish Mix anymore.

How long should i wait before using Bloom nutes? There are few pistils now here and there.
