hey brother how are you, from the photos it seems to be going well, the shanti 3 is looking killer, the 1 is very similar to my sk91 by the length shown, for you to have an idea, mine in a 500ml cup reached almost 1.20 it looks like it grows like bamboo.
in relation to the pests that are great that the guerrillas don’t have. But I remembered some other things you can try, I saw in some places that it is possible to make a “pesticide” with castor bean (mamona) leaves the other is andiroba oil I will test this in my vegetable garden to see if it works.
Another thing I do and I think you already do is use soap in my spray mixes, most existing organic IPM recipes use soap.
