Possible K deficiency? What do you think?
Gold1started grow question 4y ago
It seems like my Grape Diamonds may have a possible K deficiency. Edges of leaves are starting to fade and brown with the veins staying green. Lower leaves seems to be greener and they're showing signs of the K deficiency but not as bad. Would appreciate your thoughts, thanks!

I’m not a full time organic grower tho I do have experience with it and understand it pretty well.
Could just be showing up in the one plant first and it will show up later in the other.. I’d definitely up that kelp meal and try to source something with more K without other ingredients.. or at least something with a solid amount of PK and less N. (For when you flip to flower)
Langbienite looks like a pure K source from down to earth. Maybe even azomite?
Grape diamonds is a terpy girl man, I’ve run the cross with it planet of the grapes.

And ya know.. The plant in your diary looks pretty freaking healthy overall.. so if it’s just a leaf or three showing that, I wouldn’t overreact too much

Thanks for the quick reply! Trying to navigate organic growing with most of my experience being with liquid nutrients.
I'm not quite experiencing the same issues on my bubba which gets the same nutes. The only amendment that I have on hand that's got a good amount of K (besides the all purpose) is Kelp meal. Do you think I should just double up on the kelp meal? Mag shouldn't be an issue as I've got a good amount of dolomite lime in the soil already, but I can add a bit more.

Just checking out your feeds - you are very low in K for what canna needs.
You’re overall NPK with all those worm castings is probably something like 10-6-4. You need that value to be up around 10-15 IMO. At least matching the N content.
You may also be dealing with some Mag deficiency on top of that.

droplets on leavesWhy are there droplets all over the edges of the leaves? This happened shortly after FIMing in the PM, and they were still there in the morning. I had also watered the plant but not on the leaves. Condensation from humidity? Or is this a stress excretion? Something else? Thanks!

Fan leaf finger progressionI read somewhere that a healthy plant should increase fingers with each set of leaves. Wendy had two 3 fingered leaves, one of which wasn’t clearly defined. The next set of leaves look to have one with 4 fingers and one with 3. Should I be worried? Does she look healthy?

In addition to former questionI am growing on Cocos mix. I add Calmag 1 ml/L once a week. I do not measure PH (never did) because of organic nutrients. no runoff, I like to keep my plants a bit dry (about 150 mBar on Tensio) for better rooting. So just more Sugar Royal? Daily 1ml/L instead of 2ml/L weekly?Week 4
