Potassium deficiency?

[bushdktr]

Hi guys, I guess this is a potassium def?

Need some advice ferom the experts please!

It's a critical auto @ Day 74, under 2 CFLs and a UFO LED, on soil (peat based) feeding on organic flowering nutes, pH going in is 6, going out is 5.

Thanks!

@Waira should be able to sort you bro.

Looking at it further and seeing she is 74 days could just be her finishing up bro and eating into her leaves, if so would just put her on plain water from here flushing her and checking trichs.

I agree with Spanglish.

Yeah, thank guys, I also thought so, it could be just finishing, she's got some milky trichs, and I know the nutes have enough K in them.

...yup, it's almost that time! Those aren't P or K defc. symptoms anyways, though both often show by harvest time,.. truth is, I never found out exactly what causes that odd yellow veins/green leaf thing...-but more than one thing causes it; she looks rather green still, in fact, for a plant this ripe! I see older signs of N toxicity, so that's probably why,... anyway, like Spanglish says, cleanse her out for a few days or so, no nuthin', even if it's organic (no need to flush, which is pouring 2-3x the pot volume size of water through the soil; cleanse, at least for conventions' sake here, refers to a several day period prior to harvest of giving just water alone, to clear out extra lingering nute's-- makes for much finer smoke!).... too late to deal with the low pH, so just water, preferably something with some hardness to it, like tap, for the pH buffering minerals in it,...

Thanks Waira! Have a nice weekend you guys!
