Super soil growers ever come across any deficiencies? See a couple lower fan leaves I removed today. I'm sure leaf loss to some extent is natural, but I read that the lower leaves are your indicators, so I wanted to run these by yall to see if you suspect and deficiencies

Hello @NullHypothesis ! Yes you can experience deficiencies from super soils but having a deficiency doesn't necessarily means that your soil doesn't have the nutrients. Deficiencies can also come from over/under water and other reasons. What recipe of super soil you use? If you made your own you might didn't use enough amendments. Also did you let your soil to compost before you use it? If you didn't then the nutrients in your soil might not be available for the plants yet unless you used fast absorption amendments like blood meal, guano's and stuff like that . I wouldn't advise you to use any PK since the philosophy behind using super soil is to avoid bottled nutrients. First check your watering cycles and second use a basic compost tea. It will give to the soil large populations of beneficial bacteria that will brake down the organic matter very fast. Happy growing ! šŸ‘

Alright so here's what you can do to fix your situation. I'm noticing on the picture of the leaf obviously yellow but what catches my eye more is that its blotchy and has spots . That comes from a CalMg mixed with nitrogen/potassium deficiency . The reason I say this is I can see the browning spots on your leaf which is lack potassium the yellowing comes from the lack of nitrogen In order to correct this from happening you can buy CalMg and PK supplements for very cheap at your local hydroponics store . Another reason you having trouble is because these lady's are getting ready to start flowering any time now and your going to want to boost the PK so it helps facilitate the transition into flower as well as promote new bud sites and bud growth . I wouldn't worry about giving it Nitrogen now tho like I said these ladies are ready to go into flower and during flower they use way way more PK then Nitrogen . Over all your plants look happy and healthy except for the minor things I touched on in this answer . I hope the info provided helps you on your journey of becoming a Master Grower ! - Happy Growing!

Even super soil will eventually become depleted with time unless you transplant to a bigger pot. Those leaves un the picture are a clear sign of potassium deficiency. If you want an organic way to supply some K, make banana peal tea.

If your Plant would look everywhere then you would have to add more nitrogen, as she is streching / going into flower. But if i look at the other leaves i have no fears for your ladies, but be aware, watch out for fading/ yellowing leaves. Then you have to give them Nitrogen maybe one or 2 times for the stretch
