Hollow stems in brassicas and other plants is attributed to boron deficiency. Moses brought it up a few monthes ago.

Cut through a node on hollow stem clones for a better rooting rate.

Hollow stems are caused when the plant does not have sufficient Ca, B and Si when it is building frame. This is most often seen in plants grown with salts.

All of the formulas on the market tend to emphasize N and K to excess cause it makes things that dark green color with really fast growth. Problem with that is the frame is not built properly

So what I'm reading here is my blueberries plants which are on the same nutes and in the same soil as the mob are deficient in something?
So it's not because they're different strains? My plants all look healthy though and the blueberries are the best looking plants out of the 2 strains but they're deficient?

It don't make no sense to me but I ain't no plant scientist or done any fancy courses. I'm just saying what what I see.
My blueberries have had hollow stems 3 weeks into veg I noticed as I had to bend them because they were growing tall compared to the mobs. So the blueberries have had hollow stems from the start. How could they be deficient that young?

Lol I've just seen what thread this is in... I'm sorry I will shut my mouth because I have no business talking about botany and advanced growing science lol

I just grow

Ah Cmon bro, stick around and put your 2cents in! Even TonyGreens plants looked good. But they had hollow weak stems and I think some slight red/purpling on them? I could be wrong about the coloring though..

He upped the calcium and A couple other nutes and the weak hollow stems went away. Yields increased and more of the Strains full Terpene Profile showed in the flowers of that grow..

ganjy would you be able to do some experimenting with A plant or 2 that have the hollow stems?

[ganjygav]

Again I don't pretend to know what I'm talking about but my tap water is full of calcium I know that much.

I'm using the whole biobizz line up and I would like to think with that and allmix soil I have all bases covered. I pay enough for my bottles for it to be that way anyway lol but we don't live in a perfect world.

I read threads like this and it makes me think there's something wrong with my plants. I'm a hypochondriac for my plants, if I read something online about plant problems I start stressing that my plants have it haha.

I even went and sat with my plants last night for 20 mins or so last night inspecting them after reading this thread.

I'm happy to read what's being said but I don't feel I have anything valid to add to this thread without doing my own head in haha

So I did this massive seed run (124 beans) last year and all plants were in excellent balanced grow medium....and guess what I found when I was cloning the tops? Two had completely hollow stems. One even began to split at the end after 2 days of water soaking. Visualize a 5" clone with few leafs and a normal fat stem with a 45 degree cut (made days earlier) was no longer flat but stem appeared more more mushroom like. At the cut, the hollow stem was split into 4 sections and flared outwards with stem sections protruding out 1/4" on all sides. The other hollow stem cutting did not flare out at the cut--but took forever to root (21 days instead of 10-12).

Final outcome: The plant with the hollow stem with the flared end was a female but hermied in flower (pollen chuckers and their fucking unstable genetics) and the other hollow stemmed plant turned out to be a male runt.

Stranger the strange!

I think you're on to something- that hollow stems don't matter, not all by themselves, anyway. If you have some problems then hollow stems might be an additional indicator. OTOH, no problems means no problems regardless of hollow stems.

[ganjygav]

We shall see how well they hold up when they have full flowers. I'm only on day 7 of flower at moment so bare with me lol

Of course if you google: large hollow stem cannabis

Then you will find a plethora of statements such as this:


Males that have large hollow main stems are sought out rather than males that are more pith-filled stems - the main reason are that large hollow stemmed males are better THC producers than other plants.
