2 weeks into flower, this is about when i do a little pruning, but no where close to what you've done.
It's hard to say what it will do to your yield. I would expect it to slow the plant down some. They look pretty healthy otherwise, so they should bounce back pretty well. Just, don't love them to death.

I just thought about this. I have a heater near the tent that is a IR heater. It actually brightens the tent up bc I don’t close it at night, I close the bedroom door. Would the light from that be fucking with the sleep schedule? I can tell the plants have bounced back today. Fan leafs have gotten bigger and they look more healthy. I just took this picture now. I’m not cutting anymore leads unless I’m the way of another budding site from now on.

Current mix naturally drifts a point or two over 3 days. Between 5.8 and 6.4.
Average 6.1. Coco.
Fresh res mixed every 3 days.

I've learned additives may result in unstable PH. Especially organics.

How do you grow?

i'd want that tent to be pitch black during lights off. no little leds on timers, pumps, etc either

That’s what I figured. Any easy high cfm tent side holders or just tape pvc? lmfao I had todo it for the fan in the corner or it hit and skips, plus I have two fans out of the tent blowing in all day.

I got all the lights and leds covered in the room. They look like they’re starting to bounce back now. Picture just taken. Buds are starting to take form.

I also downloaded this app called Photone and paid 6 bucks for the led full spectrum. Seems to be semi reliable. You or anyone ever used or heard reviews?

I use the free version of Photone.
Gives me a good reference. No idea how accurate.
Showing around 40dli under my 315 cmh

I guess it says without being completely calibrated beyond what they did, it’s within 10%. It has a feature I can use to calibrate it. It seems ok, and says the middle is like 900-1000 PPFD umol/m2(squared)s at like 20”. Sides are at 650/700

that's pretty cool.

i just have a cheap lux meter off Ebay. that seems way better.

I like it and seems to be a good app to reference my light off of. Even if it off by 100, I can’t watch the plants and know the reading I got at this was too much and back it off.

When you say cheap, what’s a cheap meter off of eBay? Less then 100 bucks?

23 bucks i think??? the lux part seems fairly accurate but the conversion to ppfd is sketchy i think. i use a lighting website for that conversion.

I can change it to LUX

Also. Will not run on my older android cell phone.
Runs fine on my newest, but phone sensor limited to 35000lux. Free app so no complaints.

I have the newer iPhone, seems to work good. I love that you have to cover the phone camera with paper lol. @rkymtnman I was messing around with app and figured out how to get the different readings.

 

[TintEastwood]

cover the phone camera with paper

I tried that, but for whatever reasons the app told me to remove the paper. Must be my hardware or android.

When I grew in the past I always used Fox Farm nutes. I was looking at Jacks nute line, as I’ve heard nothing but good things. I’m also shopping around trying to figure out what RO system to even get for my city water. I dry ran my setup to check for leaks and all I can smell in the control bucket is chlorine, BAD! I didn’t know if it’s really necessary to get a 8 plus stage RO system with UV. I’ve read if I use RO water I might have to add cal/mag. At the same time I also see if using the correct nutes I wouldn’t need to supplement with cal/mag. If I use Jacks with their recommendation on feeding would I need to add cal/mag to the RO water? I’ve tried researching and can’t seem to find the proper answer for my situation. This is the setup so far, I’ll be using 2 - 250w led QB’s - 4 boards total and dialed down to 200w for 400w total in the tent. Yes, it’s in a kiddie pool lolView attachment 4955854View attachment 4955853

just add 10 % house water back to ro will provide sufficient buffer
the standard is 50 ppm carbonate
