More pure sativas in your rotation can change your mind on this subject buddy

Iāve only ran haze hybrids not a pure real deal sativa yet. What did you notice? Iām in no way saying regular stems arenāt or canāt be potent. Thatād be dumb of me to say. Just meant everytime I had a hollow plant it was good smoke. I remember bc I though it was really unique. Only get maybe 1 outta 50 plants do it for me.
Should have paid more attention in biology and horticultural classes at school

Yeah I canāt say hollow or not means anything. Iāve seen equally potent in both.

L.S.D. F2 from an OG member. 64 days from seed. I could stick a pencil in the hollow 
Very stout, and fluted stems. Still vegging.

Thanks for posting! 
This would be a perfect specimen to test.
Add some solution grade gypsum and up your boron a few PPM and if the stems become solid with the next run, we do know calcium and boron helps with hollow stems.
You may even see an improvement in you final product because the plant is getting more of what it wants/needs.
You wonāt know unless you try and if you try you may be pleasantly surprised with a better end product and maybe even more of it.
I have done this myself but folks donāt seem to trust me when I tell them this.
I do concede that some genetics may be mutated and additional calcium and boron may not fix every plant, but this is definitely not typical and I have not found a plant I could not fix, but they may be out there.

Ultimately, you can only LET your plants grow, after setting the stage for that. Give them what they need, and theyāll do the rest.

Will we? I do run a solution grade Ca that actually is soluble, as opposed to any gypsum Iāve used. I use Megacrop one part which has some boronā¦ Coco w/RO water, DTW.
TBH, I wasnāt posting it as a problem, I think itās kind of interesting, and thatās why I put it up. I have had other plants have hollow stems, but not like this that I can rememberā¦ I started growing a long time ago, lol!
Have you shown progressive pics of your cure? Iād love to see them. Trust, ok, proof is in the pudding, not the telling 
All the snips I took are showing roots, they were all hollow.

The calcium can be through the roof but if there is not enough boron to move it you will not see results.
Calcium and boron need to work together.
You may need as much a 5 ppm of boron some folks use more.
No, I never took any pics.
You can see for yourself you donāt have to trust meā¦or notā¦LOL
For more info look up silica/boron/calcium synergy.

Iām just a geezer who grows weed, and got an interesting one, not a scientist like yourself. I could send you some snips, eh?

Iām just a geezer who grows weed too. 
I do love science thoughā¦
It is an interesting cultivar.
It could be some genetic mutation, but I really doubt it.
I guess I could give her a run and see what happens.
Nothing like real-world results to tell a story.
I have been shut down for the last year or so but I just started back up and I am away a lot in the summer so I donāt really have a timeline but I would like to play with it to see what could be done.
So I am game if you are.

Iāve never sent rooted cuts before, Iāll check out how to do that. Or, Iāll let you know when I can take cuts off these cutsā¦ I do know how to do that
I think it could be a great show and tell.

In times of fast growth excess N makes cells faster than Ca can be built up.
Still it is corrected with more Ca and B.

Others here have mentioned lack of carbon as part of the problem with hollow stems.
More from Slowā¦
Carbon metabolism is a function of Calcium uptake.
Shag says:
Just a few reasons why I do not suggest using a Cal/Mag product.
adding too much magnesium to your soil can actually prevent adequate calcium from getting into your plants
The excessive application of Mg fertilizer would lead to the waste of Mg resources and cause Ca and K deficiencies in crop plants during practical production .
The accumulation of K and Ca in various plant parts and their total accumulation per plant decreased in response to Mg excess.
Too much magnesium inhibits the uptake of calcium, and the plant displays general symptoms of an excess of salts; stunted growth, and dark-coloured vegetation.
Calmag is stuck ratios. No cal/mag product has the ratios right as they are extremely dynamic. Better to have a high quality Mg chelate.

Bosses donāt ever know what their talking about.
Hereās my last hydro grow. Rolly Polly bug for size.
Also, in the future Iām gonna need every technical weed thing AIād into Bugs Bunny format.

I greatly appreciate everyones comments here!!! It wasnt till I started my 4th grow that I experienced a hollow stem in the side branches. Recently, was the first time I experienced in the main stem had some hollow sections.
