Hello, growers.
I'm here for your opinions and advices again, humbled by my recent failure.

So about 1.5 year back I decided to build myself a sealed grow room. Long story short, I did it with no help because growers in my country have never heard about such thing, so some things are a bit off / useless (tent for example, or CO2 with one 450W led light covering 1.2mx1.2m of canopy). I've spent a little over $10k on equipment, including 3.5kw mini-split ac with Wi-Fi, enviro-controller, CO2 setup, 4x MarsHydro TS 3000, Secret Jardin Intense 240 grow box, two dehumidifiers etc etc. I've become obsessed with cannabis cultivation, spent every free minute reading forums, watching Dr. Bugbee's videos. Some of you can relate I guess.

Anyway, my first grow went fine, I've grown Gorilla Zkittlez from Barney's, harvested 2.5kg, achieved approx. 1.4g/W. Shit was lit, covered in trichomes. BUT I've found around 1 hundred seeds during trimming. Hermies, I've figured. It has been brought to my mind earlier that Barney's tends to herm.

Well, here I am, 4 month later, growing Wedding cake from Barney's, at the end of week 3 flower and guess what.
4 out of 16 plants are hermies! It's my second grow and it's happening again.

It's extremely frustrating for me because I'm trying really hard to grow some nice buds, I spend 2-4 hours every day taking care of my girls and I don't know if it's me or Barney's genetics to blame for that catastrophe. When I saw the nanners today, first thing on my mind was to set the grow room on fire. My frustration has reached peak levels.

Here's some info and please tell me if you see something wrong with my environment, watering/feeding or lights that could possibly make my plant herm.

Temps:
Seedling:
· Day 25°C
· Night 20°C
Veg
· Day 30°C
· Night 25°C
Flower
· Day 27°C
· Night 22°C

Humidity
· I match my humidity to my temps according to the VPD chart. During flower it's 60 day and night, it's as low as i can go with two dehumidifiers running on full power

Watering
Veg: Once in 3 days, 3.5L, plants are in 25L fabric pots (soil)
Flower: Once in 2 days, 5.5L

Feeding:
Veg: Canna Terra Vega 3ml/L, Canna CalMag 0.5ml/L, Cannazym 2.5ml/L, pH 6.0-6.2, water temp 24°C
Flower: Canna Flores 5ml/L, CalMag 0.5L/L, Cannazym 2.5ml/L, Cannaboost 2ml/L, Canna PK 0.3ml/L for entire flowering

Lights
From 10% to 70% in veg, in week1fl 80%, week2 90%, week3 100% @46cm from the canopy. Approx 1250 ppfd in the middle.

CO2
1200ppm during flower

Techniques:
I top 2 times, first time above 3rd node, second time above 3rd node too. Than scrogging. Defol before switch, than defol and lollipoping at the end of week 2 flower.

There is no light leaks, no temp or humidity fluctuations. Offgasing has come to my mind, but I have an air purifier with formaldehyde filter in it. I'm a little intense with the defol tho. And in the second week my plants stretched as hell and I had no time to rise the lights, they were @20cm 90%.

Also, there are no nanners at the canopy level. All of them are below canopy and not in the buds themselves, only in the spot where branch is dividing from main stem. Decided to pluck them off and see whats gonna happen.

Do you think those hermies are my fault, or is it Barneys unstable genetics? Ask any details, will upload photos if needed.

@Moe.Red
I will upload pics tomorrow, it's 1 AM in my time zone rn and i don't feel like getting out of bed. Hope i will find some nanners to take pics of, I spent 4 hours plucking them all off today. Other than that, there's nothing wrong with my ladies, it's end of week 3 flower and they look fabulous. Even the edges of fan leaves are getting a little frosty.

@CookiesLikeWhoa
Actually its 60% RH during both day and night. Poor choice of words, my bad. What i was trying to say is that 60% rh is as low as i can get (during night).

@Mr.GreenthumbOG
Will do sir. It's not easy to find some good seeds in europe imho. I mean if you're looking for something more special. One of the reasons why I've built my grow room was to bring some new fire to the canna-community around me. I don't want to grow White Widow, Critical Kush, Northren lights etc. That's why i preferred Barney's Cali collection over anything else. But i recently got in touch with who imports seeds from Compound genetics, lit farms etc. Gonna try these for my third grow.

@PipeCarver
I see where you going mate. Every single diode or indicator light is covered with tape, the panel on AC is turned off. No heating needed, lights and dehumifiers warm up the room. It's so well insulated that only cooling is needed. I have 16 plants. 4 plants in 4 rows. Oddly enough, 3 out of 4 hermies are located furthest from the ac, dehum and any residue light that might glow through the tape. Also there are no nanners in the buds, only in the spot where the branch is growing out of the main stem. Will post pics tomorrow.

Thanks for the replies, guys. Appreciate it
