Looks like it could be Mag deficiency, hit them with a shot of epsom salts. 1tsp per gl. should be greener in a week. best of luck

Agree. Developing magnesium deficiency. You can apply that foliar spray with the recipe above. Add a drop or two of liquid soap to break the surface tension so it doesn’t roll off the leaves. Spray underneath leaves as well as the topsides.

I use Dutch Pro and canna depending in what deals I can get.

80ml per 20ltr of A n B gives me around 1.2EC in veg. Which is a fairly light feed.

So 100ml in 47ltr seems very weak.
Any idea what your EC is?

It's standard to use a light feed with autopots but you might be going too light.

you will get all kinds of deficiencies with that bad insect infestation... which in turn just attracts more insects sucking more food out of the plant...
