HYDRO Splitting Stems

Does anyone have any information or experience with the stem of the leaves splitting open?
My grow is in the first week of bloom and I have found a couple of the larger leaf stems splitting open. I am feeding them with GH MaxiBloom, Floralicious Plus, Armor Si, Diamond Nector, and FloraNector (all by the GH schedule for RDWC). The grow room air temperature ranges from 62° F (lights off) to 80° F (lights on). The water temperature is from 63° F to 70° F. The splitting has occurred only in one reservoir (with four plants) and the plants have been consuming a lot of water, from 4 to 4 1/2 gallons a week (well aerated). The pH has ranged from 5.7 to 6.9 (at end of feed). I manifold them at week 4 and have been using LST since. There have been no signs of decencies other than a slight tip burn and curl.
Here are some photos. Any suggestions and or opinions would be appreciated.

People have tried it but it’s a wife tale, a myth, it not you’d see member over here doin it and comercial growers doin it too.
 
Howdy 9fingerleafs, I don't understand. What is an old wife's tale and why would others do it? I am not splitting the stems, they are (only a few of them do far) splitting on their own. Do You have an explanation for this phenomenon and what causes it?
 
Hahaha I totally misread your post, I’m sorry, I thought you found your stems split, and didn’t saw the pic.
That’s super weird, I have no idea what could have cause that, it looks like the cut is almost too perfect.
 
A genetic mutation maybe? Sounds interesting. Do the leaves die off or survive the stem split action?
 
I would not worry about it,, yet,,, that may be a genetic anomaly, could be light burn, but I would think that would show other signs as well. IF you use a foiler spray on the leaf, maybe these stems were wet when the lights came on and got sunburn. Just a guess,,,
 
I forgot to say that the seeds for this grow are hermied seeds from a grow in 2016. The 'mother' plant did not have this (that I remember). Over all, the plants are growing and doing well.
 
I don't remember any problems with the 'mother' plant (see answer above). There does not appear to be any damage to the leaf, no wilt, crisping, or discoloration. I was looking at them last evening and noticed one thing that the split stems had in common, they are all older (earlier forming) leaves and are located where a new growth has sprouted. I'll post some more photos that I took last night.
 
Thanks Rwise, see below for some new photos of the stems with the 'split personality' (lol)
 
DW2 well that explains things. You didn’t backcross the parental strains, therefore you have a bunch of seeds with unstable genetics. You should expect genetic variation in this case. Hopefully split stems will be the end of what you notice... but be prepared to see more variation in the rest of the seeds you have.
 
Yeah. Seems like genetic variation to me. See above as well, most likely the source is the unstable seeds from the mother plant.
 
Here are some photos that I took last evening when I was looking at the stems and noticed that all of the split stems were early stems (first produced) where a new growth stem sprouted. These plants are at the end of the first week of 12/12 light schedule. On some of the photos, it appears that the bud sites are already beginning to show.

That is really wierd. But the rest looks really good might b the way the new growth formed kinda looks like it overtook those leaves at the base which would b the reason for the split. Great grow u have
 
Toker1, The stem split could be as You said (above), but when I sampled the trim (from topping them) they have their mommy's best trait. There was no attempt, on my part, to pollinate or cross breed, the seeds came from nanners that grew on some of the buds.
Thanks for Your input.
 
Yup. That’s the thing about genetic variation in an unstable plant. You don’t know which traits will still be there from the parents, and what new traits you will find in the offspring. What you said above doesn’t surprise me one bit.
If you like her, clone here because no two seeds you have from that mother plant will be exactly the same.
 
Thanks for Your input. I'll wait and see how they turn out. I may try cloning again, I cloned a plant (just to see if I could) several years ago. It was a hassle and only a couple of the attempts survived. The bad news, they turned out to be males, I'll never take a cutting again before the sex shows!
 
KTM690, thanks for Your input. The does not seem to be any detrimental effects, yet. I panicked (BURMA!!!!) and started to worry the first thing out. I think that You may have hit on it, because they are only splitting at the sites where there is new growth appearing. I took another look the morning and there are some of the steams that just have a 'groove' in them and not split open.
Thanks for the comment, I have been getting good growth with only 220 watts of CFLs per reservoir, but I really could use a larger area, they are getting where they are hard to get to or even tell which part belongs to which plant. FYI, there are only two plants in the right hand reservoir and four in the other.
 
i just realized one of my strains does a similar thing but it doesnt look ripped apart just like a hollow canal along the petiole, will post pics tomorrow because its dark time now
