Struggling to force flowering

Hi everyone

So, I started a grow a couple months ago. It's my first hydro grow and also first grow where I have had the lights running 24hrs a day during veg.
Some of the plants developed pistils relatively early but some not at all and no sign of Male sex organs either. The plants are all growing very well and are extremely healthy looking.

I switched to 12/12 light cycle about 2 weeks ago, changed to a warmer light color AND increased potassium quite substantially.
The plants all appear unchanged by the switch and many still not showing any signs of sex.

I am perplexed to say the least.

The seeds are just from the bag, that I collected over some time.

I have a second, younger grow running simultaneously that also started with 24 hrs light. Not a single plant has shown its sex after about a month.... I've switched it over to 18/6 schedule now.

Has anyone had similar issues with 24hrs light cycle ??
Any advice would be appreciated.

Perhaps they are Canadian and just refuse to acknowledge their sex? All kidding aside, I would be giving them some dark all the way through. Perhaps 18/6 to give the plants time to rest. Than do the flip. Can you post pics of the little ladies?

Well I've switched the younger grow to 18/6 a few days ago... I'll give them 2 weeks then switchtflip them... but its puzzling me that none of them have shown any signs of sex. I'll post some pics in a bit.

Let us know what type of lights you are using too. Specific model helps. It could be that your plants just aren't getting enough light. 3 months is really long veg. However it could also be that your bagseed was very Sativa dominant and it is just a really long and slow growing strain. Photos will definitely help the diagnosis.

all i can say is that I run 12/12 from seed because some strains do take more than a few weeks to kick over to flower- vegging plants indoors is overrated and obsolete in my opinion, hard to believe they havent been stretching like crazy in the last two weeks - you may have some other problems going on under the hood that are stunting your growth, who knows, you didnt tell us really anything about the grow other than, its hydro, light cycle, and 'increased potassium' which is also vauge

Also are you sure that you dont have light leaks? What time of day is your 12/12 running? Could be the plants have never flowered because of that.

So you basically sprout into 12/12? What kind of yield does that give, because I was under the impression you end up with basically nothing. (Like an eighth or less.)

Flowering plants before they are sexually mature increases your chance of herms.

I agree that flowering lots of small plants is better than a few big ones. Fuck plant counts lol. Running from clones that have been taken from mature moms is a better move than flowering straight from seed. Plus that way if one of the phenos turns out killer, u can immediately take more cuts from the mom instead of having to reveg and wait months until more cuts are ready. Just my experience.

Using CFLs. There are 8 x 105 W CFLs in a 32 square foot space. They are pumping out about 50 K lumens... I'm pretty sure it's enough light. When I switch them to flowering I installed a sheet of orange plexiglass ceiling in the room to change the like to a warmer colour. I'm taking pics now. Just strange to me about not showing sex. No where on the net have I seen of ANYONE having a similar problem.

"Vegging plants indoors is overrated"? Can you expand on that?

The plants have been growing well and show no signs on deficiencies or excess nutrients. What more info could I share with you that may help you understand ?

its just going to take a lil bit longer. those lights might slow things down but they will show you sex very soon no matter what. long as you keep it on 12/12

Hmm, this might be part of your problem? I've never heard or seen of this before at all. Could be that the plexiglass is actually filtering more light than you think and they aren't getting what they need. Curious where you got that idea from?

I would try removing the plexiglass and see if that helps at all. Thats the only extra variable I can see.
