Yo farm fam!! Could I get some helpful thoughts on a couple plants? Let’s start with a triangle Kush. First of all it’s droopy but I’m not too worried about that. TK’s are suuuper sensitive compared to everything else I’ve grown. This one was transplanted two days ago and it more than likely A) fussy about wanting to dry out again and B) probably exacerbated by more nitrogen than it wants even though it has less than all the other strains and C) didn’t need to be transplanted yet but oh well for her.

So yeah, that’s not what I’m trying to diagnose. I have some plants in flower right now that @Captspaulding pointed out were probably P and K deficient. I missed that because I had a thrips issues that worked their way up for a while. The lowest set of leaves would get thrips damage, then I would spray with pyrethrins which harmed the unhealthy leaves and then they would die quickly and fall off. But likely I had a P issue as well and didn’t see that because of the other shit. I always suspected another issue but was too thrown off by the phytotoxic results of spraying thrips damaged leaves to want to obsess over it and it fucked up an already fucked up grow.

So now I’m just wanting to be extra diligent for the next round..

Back to the Triangle Kush. All leaves green except the very bottom two fans. It looks like Phosphorous deficiency to me (based on looking at pictures more than real experience..). But, when it’s something only showing on the very bottom of a plant like this, can it even be called a deficient yet? Or rather, is it potentially actionable?

I guess one node up from “the very bottom) is some yellow and brown tips. Those are not found anywhere else on the plant. Related to the yellowing extreme lowers, or nutrient burn? But does full on nutrient “burnt tips) show up on ONLY on the bottom two nodes of a plant before moving up if not corrected? I would assume the answer is no, it’s not nutrient burn but I don’t know..

And I guess that leads me to my biggest question which is: at what point and how does one decide they have a deficiency (or any other type of issue that requires action..) when the symptoms are only on the lowers? I know leaves shed, so just how the hell does one know if it’s naturally culling some lowers or if it’s a brewing issue?

Hugs and kisses
