So I am bummed out as to how my grow came out.

Do you water to runoff?

explain your setup.

Lighting - make model and wattage?
Extraction system - make model and CFM/M3H?
Temps - high and low?
RH - high and low?
Nutrients - brand and strength being used
Soil/soiless/hydro - organic/coco/DWC/recirculating etc?

There’s one thing that must be right before you proceed.

thats your ability to control your environment.

The biggest things that I say to people

Perfect your environment and learn how to use your choice of nutrients and bountiful harvests will follow.

If you don’t try to perfect your environment and you have no idea about how to use your nutrients then you will fail each and every time.

Yes yes...hard to untangle what's gone on without more details. Also, waiting until the very end of the grow to ask about what the problems are is probably a bad strategy... way better to ask or to do some deep dives along the way BEFORE you're in a crisis situation...that means having read up as much as you can before you get there, and/or if problems occur, read up on why that's happening.

Maybe even let everyone know what you did along the way for each step or part of the cycle. If you haven't, start with one of the 'know it all' step by step websites. You can really narrow down things by spending a handful of hours on https://www.growweedeasy.com/ they have lots of tutorials and step by steps...though there's some bro-sci in the mix too.

Also, don't look to go from abject failure to award-winning display grows in one or two goes. Look to slowly improve your game with each progressive grow.

ty Playk328, I really appreciate that, I'm not going to give up I should have known that I was thinking should have flowered them sooner as I've seen others flowering @ different heights

A lot more problems come from when people start to overthink things.. In the end this is just a plant, all plants require proper lighting, airflow, nutrients and a watching eye over them to keep bugs away, outside that they do most of the work on their own. Make sure your room has good clean air, make up a good medium for your plant to grow in, "id suggest going with organic/living soil". With organic imo it's easy to manage, you premix ingredients the plant needs and let it inoculate, after that the micro life in your soil will do all the guessing for you, from there you would just have to water the soil with clean water "you wouldn't even need to worry about ph as the microbial life will adjust all that for you".. Once you have the proper medium then you just need the proper lighting, with your marshyrdo you are already off to a good start from what I hear about their lighting. The main thing is to research the growing style that fits you and enjoy the journey.. Ive been doing this 16 years, I only regret not starting sooner..

Also keep in mind. EVERY grower messes up at one point or another.. lol, we all have our "OOPS" moments..

One thing is for sure, you do not want cold with high humidity and you do not want hot with stale air, both of these conditions is opening the possibilities for pests, mold and diseases.. You want a comfortable temp which is around the 75 degree mark with an even amount of RH in veg, say shoot for that 55% mark and then in flower if you can bring it down to 50% that would be great, if you cant then I have ran 55% RH all the way through with no problems... You can adjust the RH by a dehumidifier to bring it down or you can even moisten towels to bring up the RH if you needed.. There are ways to manipulate your environment without spending tons of money.

That’s a kPa of 1.3 and kinda high for veg. Not to mention pretty chilly

I run 75 degrees with 50- 55% rh. I have ran this temp setting for a long time now with no problems..

75 is not chilly at all.. You must be tropical based, up here it gets -40.. 75 degrees for an indoor veg room is not chilly at all.

The only problems I run into would be pests from hardening off my plants, if I get busy and forget to preventive spray then things can get messy quick, but I have pure crop 1, neem oil, castile soap and means to get rid of them quickly..

But have you tried working with the vpd? To even have a comparison? Makes a big difference. Just because it works for you. Doesn’t mean that’s the best way. Trust me. I learned that with coco and irrigation. Cannabis plants have a chart that’s widely available online that makes it a breeze. As long as you know your surface temps. It’s help with accuracy.

I never claimed my way is the best way, each person is different and that is why I said they should research the best for their growing style.. With me, 75 degrees with 50-55% rh works great, and this setting has worked well for others that I know.. As far as organics, this too has been proven to work and it is also a personal choice as to which style someone wants to grow, I do not like hydro, I tried it when I was in my 20s and it was a nightmare, I switched very quickly from that to a soil base type grow, since then I haven't looked back.

Whelp, kind of yes. Especially if you're running LEDs where most likely your LST is a few degrees below your ambient grow temperature. Lots of us are in the mid 80's in our tents. My 'lights off' temps are 77-82.

I’m not pointing at you as a know it all. Just saying don’t be afraid of humidity during veg.

im standing at 84 in all 3 right now. Lights off temps no less than 76

75 degrees (24 C) 50/55% is green zone on Pulse's charts for veg.

I didn't worry about any of this junk for years. I had a stick thermometer I never looked at and didn't worry about humidity at all if it was fine for me it was for them. Plants grew just fine. This ac infinity stuff gives me loads of info and it definitely helps.

I am 84.2 with lights on.

My veg VPD is 1.3ish average, very occasionally dropping down to .9 but mostly in the 1.1-1.5 in veg. Once I get into flower and things start bulking up, I'll drop my humidity where it sits now 59%-63% to something in the 50-55% I've done this previously and found it worked well without any issues with PM, etc.

Yeah you could go higher with RH in veg, for me my room just likes to stay at that 50-55%, so its easier for me to just not mess with it.. I use to veg and flower in that room and the RH never fluctuated much between the 2 and I still had no problems with that either, now I veg inside and flower outside in my big garden beds..

My lights are out right now, and I'm at 82f degrees. My LST ranges from 2 to 2.5f degrees cooler than the tent, so that's me sitting at 80f during dark. Because of how my tent heater works, it sometimes drops to about 78 before it trends upward...and my Inkbird controller is set for 82...since during lights on my tent remains in the 83-85f range, the heater only ever kicks on when the lights are out.

Same, I never really put any thought into it, my RH has been in the same area for the whole time., it fluctuates slightly when winter gets here but its not enough in that room to even be concerned with..

1.3 kPa is noted for mid to late flower. And considered high. So yes. It’s the sweet spot for harvest time. But like you said it yourself.
worry about what works FOR YOU. I know iv said it over and over again. I’ll tell you if everyone could agree on that part. This community would get along much better.

Iv also noted from another sources potency can decline and increase yield from Maintaining the sweet spot and not including any stress at all. But this all remains words of mouth. Nothing scientific to my knowledge
