Help! Noob with Biocanna

I've been reading many threads on biocanna and half the people say you have to feed really heavy and the other say you have to feed really lite. so i'm a bit confused as where to go from here. I'm growing in 3.9 gal containers with 3/5 Happy frog soil,1/5 earth worm castings, 1/5 big & chunky perlite and bout 5 tbl spoons of dolomite. Everything was going fine, then i started getting some yellowing of the lower leaves bout 3 weeks ago, gave it a real lite feeding and the yellowing slowed. next feeding i gave it 1/2 strength(8 bioflores, 8 bioboost) and yellowing continued unchecked + there where brown spots. I gave her a lite flush(7 gallons) and fed her 5 bioflores, 5 bioboost, 5 humbolt honey. Now the some of the worst effected fan leaves' tips have browned and curled up. Is this nute burn, deficientcy or am i way off?

Also this strain is afghan kush, not quite sure the seed company but it's supposed to be land race

Man, I know what you are talking about. I have been trying to figure it out too. I have a plant that looks like that and everyone is telling me that I am starving it, so I will be upping my nutes, if that helps.

I use camg+ 1.5ml/gal, mineral matrix 0.5ml/gal, and synergy 5ml/gal with every watering weeks 3/4-8/9 of 12/12. I actually use the camg+ and MM every time I feed from week one veg. until I flush. I use bio-vega weeks 1-3 of 12/12, then i use 2/3 vega + 1/3 flores in week four (10ml/5ml), then I flip that in week 5 and run that until the end. I feed almost every time I water. Not sure if this is the answer but I have been working on diagnosing this issue with some of my strains and it's what I've come up with for the moment. Sometimes instead of upping the nutes you just need to fill in some pieces.

It's a deficiency, not burn. You need to add some Cal/mag to that lineup, even with the dolomite in the soil.

Another case of Ca+Mg!? Seriously, we need to have a sticky on this!

this makes sence to me. the camg+, i assume is GO? I've been looking at getting some mineral matrix but for now i do have some earth juice microblast. I'm gonna feed her with some camg+ may be a little micro see how it goes.

I've been followin yours and matt's threads. hopefully i can figure this out.

Yeah, I've been using the go camg+. Like I said, I use it all the way through, and at this point I wouldn't go without it myself. Especially with the biocanna line. I like the MM a lot too, and... all of their bottles have a picture of Zappa's face on them which has to be good...(anyone else notice this?)

RULE OF THUMB: if a leaf is more than 50% damaged remove it.
check it out: Use Bio Vega in conjunction with Bio-Marine from GO. You will never have and N deficiency. Then your even mixing up the N sources that is available to your plant. Also you must use the CaMg+ from GO but dont start using it until you switch the lights.

You want your plants to take a nice soft yellow look about a week before harvest. N is directly related to chlorophyll, thus the reason your plant is GREEN. When you cure your buds, if they have a bunch of chlorophyll in them they might just end up smelling like rotten hay or shwag. Let your plant eat it self a little in late flower to help shorten the flush.
