Can’t identify exactly whats wrong with my plants

kannab15started grow question 5y ago

My plants all have the same yellow leaves like this falling straight off the bottom canopies. I have tried to find everything I can and have nulled it down to either magnesium or nitrogen deficiency, however I can’t identify what these tiny black dots are. I dont have pests

tiny black dots look like pests , maybe even spider mites, check your leafs if that's the case and they all have these dots then you should use bacilus thuriengiensis to battle the outbreak. if you have enough time until harvest you should might save the crop. Hope this helps ! 🚀

So looking at the last 2 pictures, what do you guys think? Lack of nitrogin or magnesium? Or is it because she doesn't need the big leaves anymore? Thanks for answering!

Yellow tint on new growth I've spotted some yellowing on new growth. I'm just in the end of Week 3 and am thinking it's caused by nutrient deficiencies? I've been sticking to 0.25ml/L and am planning to go to 1ml/L starting Week 4. Does anyone have any other ideas?

Deficiencies? Brown spots, yellowing and purple stems What is this deficiency or maybe toxicity and whats the solution? She is fed with biobizz chart instructions but with every other watering. She is big so I'm guessing I should water with nutes every time? She showed this first week into flowering.

Anybody got any idea with what's going on with these 2? The 2 larger plants are showing the signs of some stress on the fan leaves. Oddly enough the runt of the 3 is not showing these signs. Has anyone seen this before or can help me identify it?
