first grow white widow fem

[principlesarelife]

Day 20 Brief update
Trimmed away most of already dying little round side leaves. Couldn't cut some of it off or I would've cut new growth.

Leaf temps were 75-77f so I adjusted the fans to give a little more direct breeze, without having to minimze light intensity. High of 76f now. Will Check tomorrow if I need to inch light higher.

61% RH

Fan breeze is tussling the plant a little bit.

I read that I should wait until the 5th node before I LST. I want to SCROG my 2x4 space with my single plant. I want a monster Bush WW

not to bring any1 down but any white widow is bs the original is black widow

Day 23

yeah, i'm being obsessive, ik ik. But she's so beautiful!

She's super short & bushy, only 4 1/4' tall.

got lights to 32" away just under 15k lux at top leaves.
readjusted circulating fan & passive intake vent right behind the stationary fan, which is pointing just below the pot's rim, gently tussling the plant on it's highest speed. humidity from humidifier is now somewhat blowing onto the WW.

leaf temps 73-77f. exhaust fan is set to 2-3 so the WW leaves stay cool.
RH sensor is reading 53% even with some of the humidifier's humidity being caught in its air flow. IDK of a more optimal place to place the humidifier without the leaves getting condensation. my home's RH is 51%
recommendations?

i'm dabbling with the exhaust fan setting between 2-3


she's developing new leaves beautifully on each of the 3 nodes! she's growing up so fast :') *demonic voice * she needs to grow up faster

day 24
update

got RH up to 68% & highest leaf temps are 76f now, thanks to the humidifier being rotated. plus, the condensation is being mitigated by the low-mid tussling of the fan blowing on her. airflow & humidity is lowering max fan leaf temps

a lil dirt is sitting in the humidifier reservoir. i'll need to rinse that out soon

just a little drooping happened this morning from a lack of watering, hadn't watered her for 3 days to be sure i wasn't over watering her.

began lsting using gift wrap string & mini clothes pin. it's the perfect string for the job. its white, sturdy enough, wide & thin!

my plan is to gradually lst her. i want to ultimately lst & scrog her. i am avoiding HST so i don't further prolong veg phase. i am already planning to veg her to the max. i've read WW doesn't stretch much during flower. considering she's very short & bushy already, i hope to scrog the screen as thoroughly & evenly as possible before going 12/12

as i lst her, should i remove the string to see if she stays in that position & then further lst her?


4th node is showing early leaf development
lower nodes are beginning to develop new, vertical sets of leaves!
i lsted her a tad more aggressively after i took this pic, just below the 3rd highest node

You've done more to that WW in 4 weeks than I do to mine the entire grow.

Humidity is too high as well. You want to cut that to 55 percent tops. Much above that WW has a nasty habit of getting powder mold. With 68 percent humidity you're practically begging for it.

You're also over feeding it. It's showing signs of nute burn already.

You're quite literally loving it to death.

not to bring any1 down but any white widow is bs the original is black widow

Wow, didn’t realise that! Good to know!!

 

[TacoMac]

They're different plants, idiot.

Black Widow is 50/50 indica-sativa.

White Widow is 60/40 indica dominant.

White Widow is also much higher in CBD than Black Widow is.

It depends what you're looking for as to which plant you grow.

appreciate your input @TacoMac !!

are you sure RH is too high if it's getting plenty of air flow? i'm under the impression the higher RH encourages new growth.

what leaf indicators indicates to you that she's receiving too many nutes?
i did begin half strength with GH nutes, per the label's max feeding schedule. also, i did full strength on myco+ root simulator so maybe that caused a lil nitrogen burn.
did full strength with calmag too

then...
i last diluted that nute concoction by 40%. wondering if it'd be best for me to concoct a fresh nute/water solution.

WW is pretty mold resistant. 60-65% RH will benefit you in veg. Flower 55 or under and density of growth need to be managed. It can get pretty crowded pretty fast. It stretches pretty dam good. Mine is a little over double but of course pheno will play a role. You can lower your day night diff to 0 during stretch for the first 3weeks of 12/12 that will help keep it down but you will need some pruning after week 2 to help with air flow.

 

[TacoMac]

Your impression is wrong. Higher humidity breeds mold and fungus and nothing more.

You've already got ripples and discoloration on the leaves. That small plant in a pot that large doesn't need nutes at all for the first 6 weeks or so.

But continue feeding it and burn the shit out of it. Learning from mistakes is typically the easiest and fastest way to get on the right path.

@Aqua Man where'd you get your seeds? you're right about the crowding, i need to stay aware of that.

what do you mean about the day night diff lowered to 0? what's your pruning technique after week 2?

@TacoMac i appreciate your participation. goes without saying i don't want to fuck up or i wouldn't be on this forum, i'm a newbie.

if the plant is grown in coco coir & starts without nutes, how does the plant have enough nutrition? i'm not trying to argue, i want to understand why. if your why is simply, "i do this & all i know is that this has been working for me," that's cool!

i'm open for some more perspectives regarding the RH, considering it's blowing consistently on the leaves. the high RH has been helping to keep the leaf temps down & the LED light as close as possible.

 

[TacoMac]

It's not an impression i grow this strain

So do I. I get my seeds from the man that created the strain in Amsterdam. He recommends no higher than 55%.

But do what you want. I wasn't talking to you to begin with.

 

[Aqua Man]

@Aqua Man where'd you get your seeds? you're right about the crowding, i need to stay aware of that.

what do you mean about the day night diff lowered to 0? what's your pruning technique after week 2?

Your difference in day night temps will affect your node spacing. A 10F cooler night temp helps stretch it out a bit. I grow in hydro so you may want a little less. When you change to flip if you keep the same day night temps or slightly cooler day temps it will reduce the node spacing during stretch so it's not as much. But you need to be cautious since tight growth can cause leafs to stack up and that's where you can get mold. After week 2 I take off large fans leaves that are blocking bud sites but mostly you need to take off the ones that are stacking up restricting airflow throughout the canopy.

Are you scrogging? We does very well in a scrog

 

[principlesarelife]

@Aqua Man ah! gotcha! that was concise. thanks!! i am scrogging

 

[principlesarelife]

@TacoMac thanks for pushing me to do some research! according to the attached chart, VPD is better at measuring than RH.

basically, for optimal leaf transpiration i need to be in the green for optimal potential.
i'm not seeing any condensation form on the leaves.

Then you are talking about black widow.

Look ww is pretty mold resistant. If you have good airflow through the canopy you have nothing to worry about I veg mine at 65-70 for the first 2 weeks then 60-65 until flip. You don't want your humidifier pointed directly at them either. He can recommend anything he likes for his particular setup. What is important is the other factors that influence growth at certain humidity and like I said good air flow is the key.

I will send you a VPD calculator tomorrow that takes leaf temps into account. That's very important and why most who say VPD is bs think so. They use it wrong.

VPD works amazingly well when used properly.

You won't see any condensation with that RH. The issues occur when you night temps drop and that causes the humidity to spike. So it's very important to make sure this is not happening or it can create mold issues. If you are seeing mold issues with 65% RH during veg its likely because the RH spikes when the temp goes down at night.

@Aqua Man that's what i figured. appreciate you elaborating further! my air flow is currently quite optimal.

you're right about night time RH. i need to check leaf temps after the light has been off for 30 mins to determine night time RH since humidifier & fans are constantly going.
