What ppms do you feed at? what do you start at and what do you end at?

I start at 1200 and goto 1600. I give pure water for last 7-10 days but don't get fading like this. I use co2.
At max 650 ppm or 1.2 ec, coir with single daily feeds. Last 2 weeks I taper a 1-6-5 bloom formula till the last week then I cut the nitrogen completely out and run a 0-5-6 tapered feeds till the last feed is plain water.

Out door plants start flower well before the outside lighting hits 12/12. Hell my outdoors finish a week or 2 after the fall solstice.
Properly fading plants.

Annnnnd there is a proper finish off, or senescence. They dont turn yellow, or brown, they turn purple and red, from inner leaf area and work outwards.

Flower is when first pistil is formed, or when you say, " ITS A GIRL,WOOT" thats when i start my flower day count. if it takes 14-17 days to show pistils, then your cutting your finish by almost 2 weeks, makes no sense.

and yes, Far red does cut flower time down.

great job jarvild!

i run usually 12/12 from seed. I have created a strain that has finished in 45 days from first pistils showing. I use GrowMau5 night puck.

I use the puck from the very first day. They show pistils at day 21-26, from seed. the entire grow takes about 65-70 days.

Im running tests on my strain, to see the extent, the timing, the feeds. I run cocoloco, Some im letting dry out, some im watering everyday. Some i have low par, some i have high par.

I run Cocoloco, and MegaCrop, Luminus cobs (300watt max) 2pc 3500K90cri and 2pc 4000k80cri. Im doing this to definitly nail down my cross. FireOG/Lemon Thai to get the best fruit possible. Some im flushing, some im not going to flush, then see the difference in them and give a report on my finidings.

i went back and found my strain that i created, (fireOG/Lemon Thai, it finished in 45 days, but i let it go for 5 more days, so chopped on the 50th day, 73 days total from seed, I did stem split, and last 5 days 4000K, 200 watts. No 48 hours darkness. This is a fasssst strain. Had over water issues, but you can see senesence happening, and i didnt flush, i just reduced nutes. and the leave curl, like a taco, is actually trait it has when its finished. Thats what i go by now with this strain, so i know shes done, when she starts to taco like that. Its done it every single time, which is cool,lol. Oh, and I leave the GrowMau5 puck on the entire light cycle, then it goes off 15 mins after lights out.

Dinafem Critical+ 2.0 . Finishes in 45-50 days. Yields enough ;)
Some months ago I bought some seeds because 700g only in 45-50 days! I have to try it!

But very difficult strain to grow... I'm growing some of them together with another strain. The other strain is very well, but Critical + 2.0 is always with problems.
Possibly my other strain (I don't know the name of it) is a lot resistant and I have problems in my grow and never knew about them?
Or the 2 strains need different garden characteristics.

There is any place I can get information about nutrients/temperature/humidity/suplements... specially for each strain?

Theres no such thing. Too many variables.

I can tell You that Critical+ 2.0 I'm growing in coco DTW.
At EC 1.4 up to 2 depending on the stage of growth.
RH 40-60%
Temps 23-28°
12/12 and even 11/13 for the light schedule after the flip
Im using MegaCrop dry nutrients and 1g/gal of epsom salt.

One problem thats consistent with them is they are constantly hungry, wanting more cal mag under LEDs and strech a lot.
Your problem was probably that they wanted more nutes then other strain that You were growing.
Your best bet would be to check a lot of grow threads and try to pick the right information from it. Learn how to read Your plants and If You have a problems how to fix them by changing one thing at the time. Dont be afraid to ask questions. Theres always someone more expirienced then you here (no matter how good you thing you are) that is willing to help. Start Your own grow thread and You'll find out ;)

90 cri alone shaves off 5-7 days from my experience
They finish 1 week earlier but with small yield correct? I think I prefer use 80 cri and bigger yield.

If I get 3000k 80 cri cobs and add red leds what will happen?

I have to buy new cobs, not sure if I buy 80 or 90cri. I read experiences, where they put side by side and better yield for 80 cri, spectrum not so good as 90 cri but more light.

Now you are saying 90 cri finish faster 5 - 7 days. That is a reason to buy 90cri.

Possiblly, the problem is with my low temps, and Critical+ 2.0 is more sensitive to cold? I will start a thread with good photos after the flip, possibly someone will find the problem.

Tag me when You do. I've grown that strain few times already. Cold temp will slow down intake of nutes and cause deficiencies.

Your best bet is to look in rapidled and digikey.

45days will be less than 50 days will be less than 60 days.... etc.. you are paying for the difference, in power and time though. I just run 3000k raw, I couldn't be arsed with funny spectrum, I'll just add more strips if I want more light.
Which CRI are your 3000K leds?

No most breeders list actual flowering time from flower set dude. I've been doing this a long time. Some breeders will actually list 12/12 time.

That being said there are many more pollen chuckers selling seeds then actual breeders that know anything about botany and genetics. Some of those pollen chuckers started as internet growers like us and might count from 12/12 but that doesn't make it biologically correct to do. The more accurately we can understand the plant the better we can grow it. Counting from an arbitrary number like 12/12 is not accurate at all. Counting from 12/12 is a lazy over simplification that only some online pot growers use.
even if the gear we are running was sifted for indoor growing ?

heres an update, 12/12 from seed. Using Luminus cobs, (300max watts)GrowMau5 puck, ran all daycycle, 15 mins lights out.

Big plants are 43 days from seed. Now, understand that i start day count when first formed real leafs start to pull away from the cotyledons, day 18 flower (topped day 16)
The smallers on the left are 26 days old. 4 days since first pistil showed.not topped.

At this stage I'm using only Growmau5 flower initiators 5min after the lights out. Any idea if it would be beneficial to run full 12h along with the F-series 3000k that are 80CRI ?

Yeah, i say so, they hit the 680 and with the 730nm u have Emerson effect, which is highly beneficial. BUT, the con is, you cant forget to supplement calmag and mag, from the beginning.
