What can it be? N def?

Hello! Let the pictures talk for themselves. Please help me identifiy these.

My Wonder Woman clones. In soil. Canna Terra Pro. Water PH 5.8-6.5. No additional nutrients as of now, as I the guys in the shop said with CannaTerraPro there is sufficient food for the ladies for at least 3 weeks. Still can it be N def?



BTW there is also a good infestation of aphids which i try to fight with neem oil. But after spraying them regularly for 1 month, they are still here. I keep on spraying with neem.

Now for my Critical jack autos:



Yellowing leaves from bottom, same conditions as with the other.

What can be wrong? Any help is appreciated.

the bugs could be very well whats causing this, i wouldnt be to concerned, if i were you i would find something with some nitrogen and alot of good micronutrients and feed it with that, 1 water with nutes, 1 plain water, 1 with nutes, best of luck

Spider mites come with that. all spider mites

They are not mites from what I've seen under my microscope, but i hope aphids respond well to neem oil. If anyone know of any good aphid killer pls let me know. I'm thinking of buying Forbid 4F or SNS 217. Can someone please confirm they work? Its a big investment for the size of my garden, so I want to go for sure.

Get some azamax.

WW looks like Mg.
CJ looks like N.
5.8 is too low for soil. Soil tends to get acidic, try feeding a neutral solution (pH7) with a feeding schedule " 1 water with nutes, 1 plain water, 1 with nutes"

EDIT: Can't see any bug damage really!!
