SOG auto coco

Hello It's looking like nitrogen to me too, a good way to tell can be if the leaves pull off easily, but you're still a bit early in the deficiency so that might not wholly apply. Id say to bump the samurai up to 2 ml, also when you water are you getting good runoff? For some reason with coco its been more important for me to get a good runoff versus with soil growing....maybe it helps keep the concentration up to a good rate where the bottom of the roots are. Hopefully with the increase to 1.2 ml it will get better but if not consider going a bit higher.👍

Heya konopek! Looks like you may have some critters on the undersides of your leaves. Have a look, they may appear white, green or brown. You can use neem oil to get rid of them, use an insecticidle soap or water with a drop or oil based soap. I spray the canopy, the undersides of the leaves, the stems and soil. I do this a few times a week and when I no longer see any I continue for one more week to be safe. Have a close eye, they can be really small! Cheers and goodluck
