Day 44 i think
Last night i pinched one of the tops of the Amnesia, today its up again but that provided that 3 others tops climb up almost to the same height, they stretched 15cm+/- in one night, now i have the problek that one of them is right in front of the clip on, go figure

After the foliar all of them look better, mostly the Super, its lost its opaque green and got a more lush one plus i dont see new root foemation on her so she reached its plateu

Today im going to make a new batch of nutes, the last one came like this +/-
20220614_013557.jpg
Dunno if i should tweak anything. They are less purply, the Skunk with a ec of 1.6 instead of 1.8 got its tops a bit paler and more opaque, the Amanesia looks kinda right and the Super seems opaque and not that lush green, not many purple and they all got a bit of burned tips
Any opinions if i should lower ca or tweak anything else?

Btw, that foliar got me some brown pistils but i was expecting that

Is that just before lights on? Or what happenend?
I noticed yesterday that the part of my canopy that receives less fresh air seems to do that wilt thing on me! I need to add air and air movement, probably.

After before loghts out where the humidity was not at 70, after lights out it got a bit worse and with the watering a bit more, the Skunk is the most affected, Amnesia second, the Super and the Runt dont do it.

Maybe could be air movement but in that part it receives a lot and directly i cant add more plus in the middle of the plants the leafs look normal so i guess is to low humitiy in that zone in all my newbiness, dunno.

At the middle of the day they loom like this at around 25c and 68rh

Some loss to mold should be expected. If you grow big heads, the RH in them is crazy high. They have to be the poster child of good health to combat the constant attack of airborne spores that are everywhere. Non of that killing them off with food deprivation that's so common.
Right now, they look a little light green. Not quite as stiff as they could be. They may not have the strong cell walls we want for the highest levels of protection. They are really close though.

I think you could look at a touch more N. It's true that it can block K a bit, but N makes weight, and it's questionable if K does. They are just that bit limey.
Air flow is high. You can see the serrations picking up. Indicating water loss. This might be why they are not a stiff as they could be. I'm really picking at small issues though. You are one of those growers that can do it.

In all my newbiness, are you saying that to avoid the temp flutuations? Because i never heard about light avoiding mold so its just what i can remember Mr. Dots, is that it?

Peace :tiphat:
Fluctuation day/night <10% rh, what do you think?

Running warmer and dryer with lights on.. and no night time humidity spikes.. take leaves out too if rh is a problem.. a few here there each day so no stress. Don't water too close to lights off. Big airflow, that a bead of water will not last a few seconds on a leaf..


:smoke out:

Hi there and welcome :D
First of all, im onr of those growers that can do it? Bro fuck, i never thought i would hear/read that, thank you, even if i know its just a boost moral, i dont see myself that way to be honest.

So if i get you right..they are sweating a bit too much and raise a bit of N(calnit). I see the Skunk limey as you said, the Super and the Amnesia not so much, well i see all of them limey at the very tops where they are geting around 1000~1200 ppfd..

Thing is, in the middle of them, the leafs look perky and not droopy where i can feel the stems pushing down hard from the middle of them to the petiole, in my head it sounds logical that the problem could be lack of rh in the tops, along with pushing them and maybe not feeding them quite right and i disconected today the ground little fan that i added 2 days ago, meanwhile the weather rh droped.

I understand how they need more or less EC as they sweat more or less and thought that it could be correlated to it.
I will add a bit more calnit to see how it goes and will start to get more run off and add Atazyme every feed to see if i can manage the salt build up with the coco drying.

Well to be honest Mr. Dots i dont have a lot of fluctuation, well it depends on the weather but usually for temps on hotter days is around 4/4.5c lower at night, and the rh doesnt budge a lot also because i counter act as the weather behaves.
For instance i finish watering them now, in the beggining of lights off when they release their smell, quite strong green btw, closed tent and room and the rh is at 56%, same as the weather so for me they are not drinking since they are not raising the Rh. They raise the Rh more at lights on, go figure. Maybe its because of 2+ ec at run off, i need to add Atazyme and get more run off

Well i jumped to coco with dry salts, handwatering so the learning curve may be a bit harder, dunno.

Thanks Mr Dots

Peace :tiphat:

End of day 45
So like i mentioned before, inner cannopy, (btw they are all around 75~80cm heigth from the pot) they dont have that curved stems and leafs, ence me thinking on low rh at the tops
20220620_014346.jpg
20220620_014349.jpg

20220620_014342.jpg

And even tho you can see in the "main top" (left one) of the Amnesia curved stems where i said they werent, they got more curved after the added fan at the ground that was directed at her, so i can see a direct correlation between the dryer air and the curved stems wich btw the rh is lower at the middle of the tent where the tops almost reside
20220620_014308.jpg


And while the Skunk and the Amnesia show some them, the Super that got her tops "bruised" by too much direct wind way sooner than the other ones never got like this neither now that its more advanced than her sisters, so i also think that something on the other 2 can be off and not being properly rh but more on the feed side of things, dunno
20220620_014238.jpg

Btw she is thickening up, not as fast as she vegged, but i see them bigger everyday
20220620_014206.jpg
20220620_014210.jpg

The Skunk is already thickening a bit and i see hwr slowing her stretch and see it on the new root formation too, bottom and top of the pot
20220620_014523.jpg
20220620_012343.jpg


Meanwhile the Amnesia is still stretching a bit and i see it on new root formation top and bottom of the pot. I wondered if drying roots that were supporting new growth could be responsible for the curved stems, but the Super long gone droped new roots formation and the Amnesia is still producing so i discarded it, again i think about rh/too much air movement, basically environement or feed..well may be both of them since they go hand in hand, but with 3 different girls at different stages with the same feeding its a bit hard i guess
20220620_004155.jpg


Since the new batch only lasted 1 day and a half, i will make a new one tomorrow, maybe a bit of more Ca to up N and maybe a slight higher EC and manage the "toxic" runoff ec with Atazyme and a bit more water at run off until they stabilize and see how they go, maybe its just a bit of lockout, dunno.

Btw Mr. Dots, after foliars and being so close togheter they dry pretty fast, 10/15mnts they look dry, not 100% of course, but at lights out and closed tent after watering i dont consider that bad (?) And if i get mold i guess it will be some learning to improve the next grow.

Peace :tiphat:

Just lighter at the tops, where it's high ppfd
You can see the right pieces of the puzzle. Better than I have. I was unsure about the N, and I was probably wrong. It's likely the high light. Are they quite high in red? most are. Without the red peak this is less likely. Though perfectly possible. I have fell into the common misconception of a nutrient deficiency, where it's actually high light destroying the green pigments. Which is not as serious as it sounds.
Forget the calnit. It might even be bad, if the red petioles and lifted serrations are actually mild Mg signs. If it were low Mg and your source is epsom, you might also have low sulphur. It's not very likely, but sulphur can give an overall yellowing. I'm just thinking out loud here though. I have not seen them top to bottom.

High light causing mild bleaching seem quite likely. As otherwise, nothing stands out to me as worth addressing. I'm not sure how this will tie in with mold issues.
