Yea i figured that. I had her on like 4ml nute strength and read about the lucas formula and just went straight to 8ml dosage. Lessoned learned...im just gonna gradually increase only to the point of leaves turning dark green then stop before tips burn in future.
Thankfully the damage wasnt too extreme.

Yeah, if you had a cal. def., it can actually contribute to the nute burn... but doubling nute % is most likely the culprit. I started using half tap with my RO water. No more necrosis at the leaf margins. Meant to say that your grow looks sick (in the good sense)! Can't wait to see how big those buds end up!

I am also scrogging my single Tangerine Dream in a WaterFarm, and am concerned about the stretch.UPDATE
Ok I encountered some bumps along the way.
Underestimated the 12/12 stretching
Next time switch to 12/12 at 25% screen covered or extend box higher
Did some LST to reposition some tops to the sides instead of directly under intense light area.
Luckily I have a fan blowing up into the hood which is preventing scorching on tops.
*Placed Hand above Tops near bulb for 1 min. Light warmth nothing hot*
As both methodologies are new to me. (I am Hempy man at heart), I have a question or two.
I am way behind you, still in veg and after looking at my grow compared to yours, I estimate I am at approx 25 to 30% fill of screen on a 2-1/2' by 3-1/2' screen (originally thought 40%, but then counted bud sites & empty screen holes).
Unlike you, I have fixed headroom of approx 20" to 24" above my screen that would allow for additional 15" to 17" clearance from my 600 watt light.
I am under the impression that with ScROG, if done correctly, it will encourage more mature bud sites that result in shorter cola like structure with the even canopy potential.
Your bud sites/colas look ginormous-ly long...as every other grow I've seen with this strain, ScROG or not.
So, how much weaving did you actually do with your grow? (weaving, in my definition is pulling back under & repositioning, not weaving over & under the wire of the ScROG screen)
I ask this, as I am under the impression that the more I fill my screen, the smaller, but more bud sites/colas I'll have, and at the flip, all the plants juice will go into pumping these bud sites, rather than continued stretching/lengthening of over all height, were she grown vertical or under the screen.
For info, I have topped UB style and super cropped before I hit the screen which is approx 12" in height.
Any insight/information you or other experienced scroggers can give, would be greatly appreciated.

Thanks Serapis, so if I follow you, this thought is partially incorrect as it does not take the flower stretch (plant elongation) into account:
and at the flip, all the plants juice will go into pumping these bud sites......
Where as, the flower stretching will commence at the flip, regardless of the amount of fill of screen, so best to flip earlier with big "known" stretchers than to wait for 80% fill.
I think I got it............common sense should have told me....but I'm not known for that, and am really a newbie at ScROG.

dishinit,
The TD is a real strether. Dont wait until 80%. Also i would recommend going light on the nutes during the transition to 12/12 to help control stretch especially if your TD pheno is looking more sativa dominant like mine.
I waited to long before the switch and didnt cut back on the nutes.
I had all my growth pulled under the screen and they still strecthed as much as they did for about 3-3.5 weeks i believe. I didnt measure but they stretched almost 2ft for my main branches.
I am running into problems in flower now. I overferted and im now struggling to keep her under control. I have yellowing on mid leaves and browning. Currently feeding just ph water for now. It seems my TD doesnt really like ferts in the flower stage unlike in veg she was a real hungry mother.

Thanks for getting back to me......especially with your Hands on experience.
Really sorry to hear you ran into a bump so late in the game. Sounds like your headed the right direction with a good flush & lowered nutes. I suspect the TD, with a 10 week flower time, suffers from an N deficiency about mid point and later during flower if all your giving her is high rates of bloom.
If your having mid plant fan leaf yellowing, look for a way to add back some N, without overshooting your overall target ppm.
My plan is to start with 50/50 Grow/Bloom mix at the flip and gradually dial back the Grow to zero about the 5th or 6th week.
So a few more ScROG questions............Were you able to train main branches during the flower stretch, mine main branches are getting thicker and only have real flexibility in the last 3" to 4" (maybe a scootch more).
I was originally thinking of an X pattern on my screen, and filling in the middle with trained undergrowth/side branches, achieving this by pinching/chopping off the ends of my main stems as they reach the outer points in my pattern.
Now with the stretch you are referring to, I am wondering if I can train the main stems to follow the edge of my screen.
The problem being the lack of pliability as I get farther into flower. I suppose I could "try" to tie a main stem off and direct the pliable part to gently force a curve, and may need to do so right now.
Would it be alright to post a photo (after figuring out how to do that) of my scrog attempt here in your journal so that you may look and advise with some more certainty?
I really appreciate both you and Serapis help.

Post away....the more info/pics of TD the more helpful.
Regarding scrog training..
I was training the growth in flower especially during 12/12. The initial 12/12 stretching is when you are gonna really start to do alot of training/maintaining existing growth and the tons of new growth that will follow. You may have to do some lst to your main stems. Its a good idea of training the mains along the edges. You should see alot of side branching once you go to 12/12. If it doesnt look like it now it will be during the stretch.
So once you figure out where to position your mains get ready to train the new growth that should xplode out of them.
Good luck and hope your TD turns out great.
Oh btw did you cut some clones? I took four cuttings in veg and they all made it thru. I now have another 7 cut from flower under the screen. Still hoping those root.

They will root for sure just give them time and love, I took some off my Green Crack 10 days ago that was in flower for 11 days and they had roots coming out the riot cubes today nice BRIGHT white to. great looking grow so far even with the little issues, Im having some to so your not alone.

I thought I'd give an example of the stretch I experienced over the last 2-1/2 weeks....Forced me to tear down old, and build new 4' X 4' screen....I keep thinking she's slowing down....but maybe that's just being pessimistic.

ok dish, i'm joining the scrogg club....lol, looking at yours stretch im a lil worried i started late on mine, well see, looking nice n healthy up there

I'm following your posts, and would venture to say your stretch will be less than mine. Your TD pheno type, coupled with your pre screen training is going to be something really special. I look forward to following your grow.

thats cool, i'm following too...lol
the indica pheno & the fact i'm not using hps i think my strech will be minimal, i hope so cos they squashed already...lol
