Doc Bud's High Brix Q&A With Pictures

Hey, guys! Hoping to get a little advise from you all. My plants are a little over a month old, and just got their first growth drench last Saturday. The plants were also up to their 6th pair 5-blade leaves, so Sunday morning I went ahead and topped them, just at the 6th pair of leaves.

So everything has been looking good, but this morning 2 of my 11 plants had discolored leaves. The discoloration is close to the base of the plants, and all the other growth on the plants is looking good. Here are some pictures.

This is one of my Blue Dream plants:

And here is the other plant affected, one of my CBD Critical Cure plants:

As you can see in the pictures, overall the plants look good. It's just those few leaves of older growth that show the problem.

Is this something I should be concerned about? Is there anything I should do, or just let them be for the time being? All the other plants look fine. It's just these two.

Please let me know what you think. Thanks, guys!
 
For me I wouldnt be worried to see that on such low leaves. They are often sacrificial to the rest of the plant. Some destress might be my answer. If it spread further I would think about a rescue.

Your plants look lovely to me by the way.
 
Plants look great, SlowToke!
Could it be from foliars being a little heavy - maybe dripping down on those spots from upper leaves?

Thanks, Shiggity. I'm trying not to overreact, but thought it best to check in with you guys.

I haven't done any foliar sprays yet, so that wouldn't have been the cause. Maybe just one of those things, like Shiggity said, not to worry too much about right now. I'll keep an eye on them over the next couple of days, and if the condition get's any worse, I'll try a destress or rescue treatment.

I did have a general questions about when to start the foliar sprays. The Brix foliar should be generally given once a week throughout the veg period, correct? And should I start now? I also gather I don't need to use the destress foliar unless I see a problem. Is that right?

Thanks!
 
I use both foliars EVERY week, after the 5th node.
Graytail had me try Brix at 1/2 strength twice per week and I'm liking it (except I'm spraying every other day now).

But only when the leaves are looking great - THEN boost 'em.

My first thought was Brix burns, too, but it's not really the typical copper color - more like internal necrosis. And ... no foliars yet, so ... :cheesygrinsmiley:

:hmmm: Nutrient deficiency/toxicity, yes ... but what? And it happened quickly ...

But I agree - it's not a welcome thing to see, but meh, no worries yet. Watch how they progress. The lower leaves are almost always goners eventually, anyway.

Again I would say that outdoor is far different during the night than our indoor. We must be careful discounting the effect of the far red light in late summer/fall. Studies have been done indoor with short day plants (cannabis is a short day flowering plant which actually means long night). Flowering was prevented indoor by flashing a light in the middle of the dark period each day. This is of course why gas lantern routine works well. If that same light was flashed followed by lighting from a far red bulb then flowering commenced/continued.

Its all about phytochome. Phytochrome has two light induced conformations Pr and Pfr. 660nm light will shift Pr to Pfr. 730nm (far red) will shift Pfr to Pr. If phytochrome is in the Pr state then flowering commences or continues. If it is in the Pfr state flowering will not start or ceases. Outdoor these light flashes by headlights etc, are counteracted by far red light reconverting any Pfr to Pr again. Indoor, there is no far red light in the dark cycle to do that. So if we flash a light in thee darkness it takes approximately 2 hours to convert Pfr to Pr again. If that happens just one time its not going to be a big deal. Do that quite often and there may be issues with reduced flowering response i.e buds that stretch and go half veg, hermies, reduced trichs and terps, etc.

As far as sex reversal or nanners I think that is mostly genetically determined. So if your strain is not hermie prone then having night time light issues and irregualarities will probably not make a female plant produce nanners. If it is a sensitive strain then you may have issues. Especially if there are other stressors present like excess heat, infestations, over fertilization, etc.

For me, once the lights go out I don't mess with it. Once I get these far red lights if I need to go in, I will just turn on the far reds and be confident nothing is awry.

Man... That was impressive. Did you just type that out? No copy and paste? If so you are the man, I don't think I have ever had someone explain this so clearly. I am almost certain the led flashing was what jacked it up. That and the heat which I am about to remedy. I had ordered a cool tube but it was too long for my cabinet. I found a glass place in town that cut it down for me. As soon as I harvest ima set that up and will be off flowering the Wonder Woman. I was reallt impressed with how easy it was to grow this jock horror auto out in subcools' super soil. I think this round will only be better, temp, humidity, air circulation should all be dialed in by the time the WW is done. Then ima Brix it.

What kind of light are they under and how far away is the light, etc?

First of all, it ain't no big deal. It looks to me like one of two things:

The lower leaves aren't getting much light

or

Your roots aren't completely happy.

You just topped them, so do give a DeStress Foliar, 1/2 oz per quart.

I'd let them get good and dry, prune off anything less than perfect on the lower half of the plant, and then do a rescue drench....let the pot soak in the drench for a good 5 minutes or so.

Your new growth is all good, but if you do what I suggested I think you'll be super stoked on what happens.

Thanks duggan! I'm here to stay. This is the direction I am heading. HI-Brix here I come!
Can you believe I read through every post here on docbuds high bix Q&A. Took a couple of months poking through so I didn't miss any action.

You are correct, I am very lucky. I was so stoked when I fell across this and everyone here is nice, unlike other sites I won't mention. I will indeed browse you guys journals, Thank you again!

Excellent point!
I'm curious about your use. I was over in your yard and saw your post about the fans gone and leaves looking poor. Do you use Brix when you have the yellowing in mid-late bloom? I'm at that stage and am unsure of which way to go. I can never keep my leaves looking good near the end.

MIdbloom fade:

WayAhead10x added to Brix! Spray once or twice BEFORE you expect the fade. It's working great for me.

But's it's taken a couple years to figure out. On the saltlovers, top dressing some bloodmeal also helps.
 
I don't trust Brix when the leaves are stressed. I don't see it as a remedy. For leaf stress, I think soil and/or ambient temp/humidity. The leaves aren't doing their customary transpiration thing, so something's in the way. Spraying with Brix would only put more strain on the deficiency. DeStress is more of a food and exudate supplement, so that's more appropriate, but if the issue is leaf fatigue, we still have to figure out why. Kinda like a coolant leak in the car. Sure, fine, add some coolant but ... where did it go? There has to be a leak - gotta find it and fix it eventually.

Bad leaves mean impaired nutrient movement in the plant, or cockeyed soil.

WA10X is a nutrient feed, right Doc?
