This whole grow has been chronicled here: The Root Brake

These pictures were taken New Years day, day 42 of flower. They are yellowing from the top down and beginning to purple up a bit.
I am on the fence as whether to feed them one last time or not. I plan on taking them on day 63, but will verify by trichomes.

I have gotten my lights off temps back in check.
The buds look healthy I just wish that they were about a week ahead with this yellowing.

Keep giving them water or hit them with one more dose of Bloom nutes?

Looks like they need a transplant to bigger pots bro, looks like the start of lockout...are they in totes? how's the drainage?

give it a try because 47 days in the same pot is a long time...good luck

peace and be safe

Buds look great!!I think it needs mag with a ppm under a 100 ill bet it started at the top fading slowly and before you know the whole plant is lime green but the buds still grow i also grow in ocean forest except i use 5 gallon buckets.Or they also could have used up all its nitrogen too early

Now that i have given my opinion maybe some one with some real skills in this area will tell us both whats up

Cool!

Cool!

What an interesting thread. The root break idea is a cool concept. It will be interesting ta see how the roots have filled the space.... I think if there still taking water at the same rate they have been throughout flowering you can feed again. They would really blow up, esp with the lil bit of N in the PBP. But, if they have slowed way down on water that means they're not transpiring at the same rate and are about done. So it wouldn't do much good. I think yer gonna have to make the call there..... They have run a lil bit short on N. But holy cow, you only fed them once through the whole thing! That's amazing! Very nice grow, no matter what happens from here on out. Thanks for sharing! Be sure and give us a peak at those roots when yer done. Take care... BC

They have been slowing down on the drinking. I have been thinking the same thing. If I wait until the totes are light again it may be day 50 - 52. I sure don't want to dump nutes into an already saturated soil mix now.

Perhaps I should lightly foliar some Cal-Mag plus OR an Epsom Salts mixture?

I have been kicking these clones in the ass with 1800PPM CO2 and 85 WPSF. Makes sense that they sailed through their nutrients.

I am surprised to see that the progression of the deficiencies are almost identical between the braked and un-braked totes.

I can't wait to dump the soil and cut into it.

45 days into flower, I don't think it is a good idea to transplant at this stage. Thanks for your thoughts though.

I wouldn't feed again, mandala strains are pretty light feeders anyways.

And for sure no foliar feeding.

Personally, I'd take em out of the pots, and put another inch of compost on the bottom, then pop em back into their existing posts. The roots should grow into the space and just draw up what they need from the fresh compost without filing themselves up on nutes that then need to be flushed out. It may not make a visable diff to the already yellowing leaves, but it should help with any further development.

 

[fideralala]

i would give 'em a nice, final or to hits of mineral bloom nutes + pk13. transplants at this stage ,,, i dunno. or just let em ...

Yes, I stripped the fan leaves off on day 32

thats like a ferrari without wheels

If they are root bound they aren't going to take any nutes from watering anyway...I would not have suggested this if i have not tried it myself before....i'm telling ya bro, give those roots somewhere to go .....i like GMT's idea...never to late for fresh medium

This plant was transplanted 4 weeks ago and harvested on the 1st...check my gallery or my threads all those were transplanted late because they were showing signs of lockout



Again i say either full transplant or partial like GMT said and your plants will start looking better in no time...don't be afraid

And leave your fan leaves on!

peace and be safe

Dont worry about it this was about the root brake and you still kicked some ass

I have been battling this same issue for some time now i use ocean forest pbp and for the last few months most of their dry amendments as well

B.C. made a post not too long ago on the same issue at around three to five weeks they use a lot of mag he says he uses hard water plus cal mag some times

I took this information and used it for my most recent grow 2 ppps and like clock work 1 of them started to fade from the top down so i took 8 mils of cal mag and 10 mils of pbp grow and i stopped it right in its tracks

Now we are up to day 33 and i just kept giving them cal mag now they are yellowing from the bottom up like they are supposed to. Before i would just hit it with more grow and no cal mag and it would have no effect just kept on yellowing

Got 3 ADs that are going in their third week now so i am going to hit them a shot of grow and cal mag early maybe i can stay ahead of it this time

What is strange to me is my ppm reading coming out of these two ppps have stayed between 1100 to 1500 they still are and yet they are yellowing go figure

In your case i would have thought their was enough material in those tubs to go the whole grow with out nutes

That looks sick. How long of flush on that?
I hope mine look like that in two weeks.

I believe I would do more harm than good transplanting. These are more or less 5 small soil beds with 12 clones each.
The pics were of the worst ones and there are others that are still green but I suspect that they are soon to follow these.
I will give them cal-mag plus and water and adjust when I try this method again.

And leave your fan leaves on!

yeah.....

I was hoping for a magic bullet cure.

Yeah that's why I'm like "huh?", at least the braked ones should be a little less yellow.
That brings me back to the temperature issue.
It was high 50's low 60's for a week or more. Do these look like chilly girls?
Sadhu says it's heat resistant so does that mean cold would affect it more (desert strain)?

Well I think you have yer answer. If I remember correctly from reading the thread they were being watered every 5 days, now it's every 10 days. The window of them feeding is gone. It goes with the rate of transpiration. No matter what you do, it's done...... Using Co2 speeds everything up. When you use it, you must increase the amount of light and feed to keep up with the rate the Co2 will have the plant cycling at, or creating photosynthesis. This all happens in the window of the transpiration cycle btw. This cycle is the time to take advantage of the plants own natural high rate of processing and feed heavy to reach the plants full potential, even without Co2. But with Co2 a lite feeder can become a heavy one!..... Maybe yall didn't read this close enough, but he's growing in tubs, bed style. So you don't just pop em out and back in. Besides it wouldn't do any good at this point...... It's kinda of a let down ta see the ones with root breaks yellowing at the same rate as the others. Sorta tells ya it didn't make much difference. But ya never learn if you don't try tho! later, BC

You must spread some reputation around before giving it to B.C. again!!

Good info as always B.C.
