hollow stalk/stems

Hollow stalk/stems are from a boron deficiency. You don't want hollow stems. Plants do not transport anything through the hollow area in the stalk, only through the solid part of the stalk.

And despite popular opinion, purple stalks are from a phosphorus deficiency, not genetics, just FYI.

You probably don't actually have a phosphorus deficiency if you're using cannabis marketed nutrients or most any flowering fertilizer. You probably have an abundance of calcium, copper, potassium, iron and/or zinc blocking a sufficient amount of phosphorus being taken up by the plant. It could also be that your plant has genetics that suck at taking up phosphorus, e.g., Blueberry. Blueberry takes a skilled grower (that is aware of this obviously) to get it to take up enough phosphorus to not have purple stalks.

And you may or may not have a boron deficiency. Cannabis is more of a boron hog than a lot of people know IMO and you need a proportional amount of boron to the amount of available calcium. Just like with phosphorus too much calcium (without sufficient amounts of boron) and/or too much potassium will block sufficient amounts of boron being taken up by the plant. Too much nitrogen is also an antagonist to boron uptake, but your plant doesn't look like it had too much nitrogen and calcium or potassium abundance is more likely the culprit since you already had a phosphorus deficiency.

These are just educated guesses unless you get a soil test though because it could be a couple different abundances or deficiencies.

Your plant looks like it turned out some really buds though :mrgreen:
That is far beyond my knowledge, so maybe it was me just dumping the wrong bytes or too much? I will start a real feeding schedule on my next batch for sure. Thank you for the explanation, and any tips from anyone is valued

It looks like you got good results with what you were doing and whatever deficiencies or abundances you had didn't kill your plant so no worries I'd say if you're not doing this for a living. If you're farming than this is stuff you should know and correct IMO to see the best results. If you're just growing for personal stash than as long as you get enough to last between harvests than it's not that big of deal especially indoors where you have better environmental control.

good lookin gal!

pack that hollow stem with cloning gel next time and graft a different strains fresh cut to it. tape a mini clear plastic cup over the area and seal it. keep it moist inside for a couple weeks, remove the cup.
peace

Ya, just a private stash. Since I butchered the others so bad I decided not to top or anything with this girl, I just wanted to let her grow. Being a Dark Devil auto I wasn't expecting a lot of bud, but WOW, that smell is amazing. The next 2 girls should make enough for me and a few friends to enjoy for a bit. I have 3 light options and I will post the set up and what I planned, plz correct me for the best outcome

Gotta grow em to figure out what you like .....we all started somewhere no problem with that ....I grew 7 strains recently and only one of them I was disappointed in ...dream star ....didn't like the way it turned out ....I grow lots of kush for my patients lots of them very sick and in lots of pain .....literally have a few large kush gardens every year

This last chop was lots of OGK ,banana OG and Bubba K
Is that bubba Kush really good for arthritis pain. I have some seeds but elected to grow something else, damn.

hollow trunks (ime) are mostly a genetic issue. hydro will amplify the trait if it is already present.
You probably can't try an experiment in hydro with a single plant, but I'd bet if you pumped up your boron a bit you'd see those hollow stems disappear. Ideally you'd pump up silica and boron to be proportional to the amount of available calcium and you'don't have solid stems as hard as rocks while keeping in mind to avoid the mineral abundances that I mentioned previously that will block the uptake of Si, Ca, or B, at least until stretch is finished and then you'd want to pump up potassium for the last 3-4 weeks of flowering to let it bulk up the yield. I can't tell you what levels to shoot for in hydro, but if you can experiment with at least one plant you should give it a shot with a strain you generally have hollow stems with and see if you can get those hollow stems to fill in.

its all good for all knds of ailments, some that help one patient dont help another, isnt like rx. now plant those seeds and watch them grow

Yeah it is really good ....better than I thought it was guna be to be honest ...out of the strains I have the OGK and the bubba kush seem to be the favorites for pain relief .......I have a real good friend who got more relief from the bubba k I grew than his pain meds ....and the lots of other people I grow for are saying much of the same about it kinda unexpected but I'm glad I decided to run em now....il definately be running it again in my next grow ....because helping these people is my reason for growing in the first place

i run with a 1-2-3 ratio in flower. hollow stems have not been a plague for me, but my opinion of genetic issue comes from starting tons of seeds over the course of years. seed grown plants of one stabilized line or a stable hybrid tend to be nearly identical. so when i grow a strain (lets use dukenukem as an example) and plant a dozen seeds, end with 9 females, and all have hollow shafts, i deduce that genes play the major role (as the other dozens of plants from multiple strains are in the same conditions, same nutrients, same schedule).

i'll check the boron when it comes up again ;). however, i think that a micro is less responsible than the base genetic code.

and totally not being dickish either buddy, promise! :)

i was impressed by bubba kush. very smooth and even, and doesn't seem to be a killer potent comatose product . but holy hell, it works for nerve damage! dropped my blood pressure too!! :D it's on my list to grow after this upcoming harvest... @Indacouch , which breeder/bank did you use for the bk seeds?
