Leaves are yellowing :(

Pretty much. Do a bit of research on veg nutes vs bloom nutes. They're different NPK values bc the needs of the plant change as it focuses on different things. Having a good understanding of NPK is super helpful.

I noticed some tiny brown caterpillars dancing on leaves... don't know if there could be some other bad boys. I think they are gonna ruin too much the foliage. I've just read that Neem Oil affects buds' taste and is not recommended in flowering.
Is there something I can use to kill this kind of pests?
Reading something about B.T. and "Spinosad", but have no idea of the effects and the dosage...

Any hint is appreciated <3

Edit:
They don't really seem to be caterpillars... They look like micro caterpillars, really pygmy, some are mostly dark yellow, others are more blacky. They only move through the main "tunnels" of the veins of leaves. I'm trying to kill much more as possible.
And.. they are impossible to take a photo of!

Someone might know what these little bastards could be? Is it ok not to spray anything, in order to keep the most natural flavor?
They like to eat leaves, some of which get cut, while others they don't manage to dig.

@doublejj @Greenthumblady ?? :???:

As regards buds, they're increasing size everyday!! 20200607_190657.jpg20200608_210015.jpg

Lucas Formula proves there is no need to rely on veg/bloom specific nutes if you are feeding a balanced nutrient regiment. There are several good 1 or two part powdered formulas that use the same base nutrient at all stages of plant growth and the only thing you need to adjust is the EC.
 
Hard to tell. I've never come across them myself. Literally google or do a search on this site for common pests and see if you can find it in the multitude of sites that will have pictures etc. Any big damage from them?

Last time I did outdoor I had big mold problems and sprayed for it... I 100% tasted that shit every joint I rolled. So I'm hesitant to advise you do that unless it's really needed.

Totally right! I just gave this as an example to lead him to research canabis nutrients and really understand their roles and the lifecycle of the great pot plant. Once he knows that, deciding on which nute line or organic amendments to go with is easier and makes a lot more sense. :leaf:

So is it pests?

It seems to be...
As regards big crunches and holes I'm sure that earwigs have done their job, as I killed those creepy bastards.
But I'm also preoccupied with these tiny unknown objects :|
Look at my previous message for infos

Yeah they look like that.
There's absolutely no big damage, the plant appears to be really healthy.
I sprayed potassium soap weeks ago, but I can see that they're back.
I remove them by hand as possible.
That's why I think that they are not that enemy at the moment, because we are few weeks far from harvest.
This works as lesson to me: next time I'll prevent anything using Neem Oil.

Ok guys I'm leaving next week, thus I'm going to harvest on Monday. Do you think it's OK? started the flushing on 22 June. Although there are micro buds with white pistils
