long flowering time

[Muskegman]

Is this normal ? I’ve never had this happen before . This green crack autoflower is taking FOREVER to change. It’s like it started flowering and just stopping doing it’s thing. The first two pics are of the same cola almost three weeks apart. It looks almost identical. And then the last two pics is one of the top of the plant and one of the lower colas. The lower cola looks bigger than the very main top cola. Light stress? 75 degree temps, 45-50 RH, 1.3-1.4 EC. 18 and 6 light schedule. Plant looks healthy with no sign of any problems. Today is day 60 from the time it came out. It measures 51 inches tall this morning. The plant right next to it is a GSC and it’s doing the same exact thing. It’s actually a little taller. This can’t be normal? That top cola just looks odd doesn’t it? I’m running timber grow lights redwood over them with no reflectors at about 12 inches. I moved it up to 18 inches this morning and turned it down a little too. Any help or insight would be greatly appreciated.

What is a Timber redwood? You should be running both grow and bloom spectrums at full power.Plant looks great but has a long way to go.Are you feeding bloom nutes?

 

[Muskegman]

Yes I am using flora nova bloom. Timber redwood is a timber growlights fixture, it has 6 vero29 gen 7 on it. Their web store says at 18 inches it’s something like 900PPFD

Anyone ????

....definitely weird, light sched' is fine, nutes OK,... and both are doing it? Then there's likely a common factor here, and I'd start with the light spectrum itself; not likely an error, but double check anyway that you have the right K temp. lights,... Even so, looking at the website, they don't offer heavily blue biased spectrum, even 4K is fine for bloom full time,... what K are yours?
Whose genetics are these? .......... are you using any other bloom nutes like KoolBloom, etc.? Usually these line are meant to be used in conjunction with each other to get the overall NKP#'s where they need to be,... Nova bloom is kinda N heavy at 4-8-7, and too much N can mess with blooming,....

Yea both plants are doing the same thing and they’re two different strains birth from fastbuds. GSC and green crack. I’ve been following growpotcheaply on YouTube and all he was using is the flora nova bloom so I would assume it’s not that. The lights I have are at 3500k and I’ve never had this happen before. Hopefully the lights were just too close and after a couple
Days I see some improvement. If I don’t, I don’t know what’s going on. Here a photo from tonight of the top cola and one of the bottom. The bottom one looks normal while the top seems spindly and undeveloped while the bottom one doesn’t. Which made me thing it was light stress up top and down low obviously not. Time will tell

..the up-curled margins are a sign of light/heat stress, so that could be a factor.... Oh, my bad, I missed the light distances,.. too close for sure before, 18" still might be, maybe back them up another 2-3",...
...all else checks out man, only thing left is shaky genetics, which Fastbuds does show more often than most that I've seen lately,... but both very different strains, makes this also seemingly unlikely..... I still suggest trying a PK booster as well,... KoolBloom 0-10-10 is a good choice.... meantime we'll see if the light elevation helps!
Also,check to see what FB says about these two for finish times, some strains can run 10-12 weeks total, not 8+, and those are under optimal conditions and early harvest windows... You can get pheno's that are long runners was well,....

and

Ok thanks a lot. I’m gonna look them up on their website . Not a lot of people willing to help on here it seems .
