Understanding NPK

Right now I have one plant in 1 week into flower. it is in a 3 gal fabric pot. Soil is Coast of Maine Stonington blend

I know how NPK works during veg and flower. ( Veg - (N) needs to be higher then p and k) (Flower - P and K need to be higher and N to be lower) so that I understand. What i do not understand is should i give her food high in PK like Langbenite-(0-0-22) and High phosphorus bat guano-(0-12-0) and DTE(Down to Earth) - 4-4-4 so those totals would be 4-16-26. or will that end up burning the plant even though they are organic nutrients because of the low N and the high PK.

Is the above NPK good for dense and big buds or should it be lower?

Any and all help would be greatly appreciated. This is my 1st grow organic / 2nd grow overall.

Organic and nutes? I’m confused.

Growing plants organic instead of using synthetic bottled nutrients. NPK (nitrogen - phosphorus - Potassium ) the 3 big macro nutrients a plant needs to grow and thrive. When using organic nutrients it is harder to get nutrient burn since plant uptakes the nutrients slowly and when it needs it. They also need time to break down in the soil as well.

Got it. I misread your post. Organic; I am mostly useless, so sorry for my intrusion.

Flowering 0-10-8 NITROGEN needed in very small doses. Higher Nitrogen is for veg.

You've got the right idea. I was scared to use langbeinite at first too, but it's good stuff. Also I haven't had any burning from bat guano. The seabird seemed a little hot though.

And if you want you could make a top dressing mix. Add whatever to some EWC and keep it moist. I also add pumice. And feel it each day. I've had some mixes get over 100 degrees.

How often do you feed your flowering plants with langbenite and bat guano?

I don't have a schedule. And the longer I have these pots going the less often they need anything.

So if you were top dress feeding how many weeks apart would you feed them? Right now I am feeding every 2 weeks. Is that enough time for the nutrients to break down in the soil?

I feed every week in 10g sips,4-6 tbls of Gaia 444, mix a little EWC with it. Your 3 gallon is kinda tricky,easy to over do but yet will run out quickly. I didn't have much luck in small pots.
