bud leafs droopy, Day 20 Flower, No other noticeable deficiencies

[DabOnDabs]

On to new problems;

Go into the room this afternoon and on 3 out of the 18 plants, the leaves on the budsites (not the major fan leaves for the most part) are getting hella droopy. Research leads me to believe this is Nitrogen Toxicity??

Im feeding Jacks Hydroponics D9 Recipe 3:2 @ 1.5 ec. I checked my runoff, and its coming out at 6.0ph and 1.5ec. Exactly the same coming out as it is going in.

I diluted my res down to .8ec, and we'll see how they react over the next day or so...Anybody have any other suggestions, ways to fix, etc. What am I looking at in my plants, and do I need to change the recipe to fix it??


Heres a couple pics of plants 1 and 2 exhibiting the worst signs

This is what the average plant looks like...Looks like they're all about to start getting a bit droopier.

Not sure if it matters, but the light closest to these two plants wasnt turned on for the last week or so because I was using it in my veg room. I just plugged it back in 2 days ago, now the plants closest to that light are exhibiting the worst signs. Doubt it matters, just an observation

Hps bro?

Hps bro?

No, incandescence.

I cut my ec in half and the problem fixed itself 3 hours later. We'll see if its temporary or not. Will update

1.5 is a little hot. Should be an easy fix.

Have you ever grown vertical before?

If not, you'll find the leaves will contort downwards to face the light. If the leaves below the bulb are not doing the same thing, then that's all it is.

I diluted my res down to .8, went to the bar, came home and everything was sticking straight out, pointy like a rock hard boner.

Papaduc, I have grown vertical before, and know how the leaves cant twist and lay in different ways as compared to horizontal... However, this was majorly a problem with the little tiny inner leaves connected to the buds, and not the fan leaves surrounding the buds.
Interesting observation tho. The fact that it was only like this right after the lights turned on lends to your experiences. I will keep observing, thanks for your input!

 

[papaduc]

No problem fella. Are the leaves below the level of the bulb doing the same thing?

If not, and they're looking "normal" that's your answer I think.

Seriously? You got the gear now spend some time learning.

Classic overfeeding. You are correct it certainly seems like Nitrogen toxicity. But can't be too sure until we see them in neutral lighting ? From your pics they look a tad too dark.
The best buds I ever grew were grown at EC 1.2. If you want to "feed" more just water more frequently instead of raising EC imho.

Thats what I'm trying to do cock. Noticed a problem, posted my opinion, asked for others opinions, and posted solutions. Isnt that what this place is for?

I was feeding D9 @ 1.5ec. Nute profile looks like this:

N P K Mg S Ca
81-28-114-34-44-67

Too much N

D9 @ 1.2
64-22-91-27-35-53

Or, theres Mister D's option to go 2g/2g and dilute to 1.2ec. This would yield;

N -P - K -Mg-S-Ca
72-19-76-23-29-67

They look fairly similar, however referencing this chart;

Im gonna go w/ mister d's recipe from here on out @1.2 ec. Looks best. Will update

Hrm.. Recipes..
IMHO unless you really know ur shit bro just use standard a+b or 3part grow nutes that work great and simple..
Bcuzz/Atami A+B has worked good for me.. Canna did too but disliked the end result.. Advanced Nutes, for all the bad rep it gets, actually makes good basic nutes and they arent that watered down like their additives, and it doesnt take more than 1ml/L to reach my EC target (1.2).
I would suggest you try some of these premade formulas as they are proven to work before you try to take it to rocket science.

 

[papaduc]

I should have mentioned, you should only need 1.2 ec at most at that stage to be honest. But the fan leaves bending down, that's vertical lighting for ya.

Like I say, post a picture of the leaves below the lowest bulb. That'll give you the answer.

With regards ratios/recipes/formulas, just go with something that's lower in nitrogen for flowering. You can always add in N for one watering if you think you're going low at some point.

Just at a glance none of those ratios look great.

8-3-11
6-2-9
7-2-7

They'd all do you as a veg feed. Put it that way. Especially the last one. That's not a flower formula by any stretch (no pun)

Use a pk booster at 0.2 in place of your base feed. So, go to 1.0ec with the base, then 1.2 with the pk. That's for now. Later on in flower I'd even be inclined to go lower with the base and replace it with more P&K. Get something like maxibloom and just use that. Save yourself the ballache. It's a much better balance for flowering and saves you having to manually adjust nutes that are not well balanced for flowering in the first place.

What's your tap ec btw?

I run 1.0 ec in veg. and 1.o-1.2ec in flower. (.5 scale)
That is plenty.
Simple A and B gets the job done.
Forget the potions they only lead to head ache
Learn it before you burn it.

I'm using jacks guys. It's two part standalone. Also papaduc... How did you get those ratios? They couldn't be more wrong. I have used "baseline" formulas, they work ok. I want to get the most out of my plants and tailor the recipe towards my plants needs.
