They appear to be nutrient deficient. A lot of cannabis related nutrients are lacking in something unless you buy ever part of a stupid set of nutrients just FYI. All of it is overpriced garbage. All of it.
Just one prime example... Hygrozyme - useful stuff right? Well, if you've used lacto products you know it is... how much? Like 500 bucks for 20L or something? Or you can buy a 10 dollar pond zyme pack and make it yourself - and a lot more of it. Or you can do a bokashi brew for almost nothing. lol. Anyway.
Anyway it looks like Maganese or Iron possibly (def). Probably lacking some other stuff too, possibly some magnesium.
Micronutrients are usually lacking in cannabis products, despite being incredibly important.
