Flower spectrum switch

first of all i don't like the yellowing on the new growth (did u feed em with P before ? if yes then u overdid) 80k lux for 12h is 64 DLI that is max for flowering without Co2 so add + 20k every week since 40k lux after 2 weeks when u'll see pre-buds u can turn on ik+red+uv (to privent stretching ) if u don't want wait 2 usless weeks of stretching (only for Photos ) u can set em for 618 for 2 weeks(80k lux),then u set em again on 12/12 i do NOT recommend 1311 or 1410 only if counterclockwise That is MY experience so do whatever u please

Hey growmie, plants look healthy and ready! You can flip anytime now. I’d switch the spectrum to bloom and gradually raise the intensity (80% sounds fine) over the first two weeks of 12/12. Half-dose bloom booster is a good call to ease them in without overfeeding. Keep an eye on stretch and canopy height. Good luck with the rest of your grow growmie 🤞🍀 ♥️

In this phase of growth, they require the highest illumination amd radiation so don't spare with light too much - full gas! Blooming will start one week from now, so wait up with blooming products. Now they need more nitrogen and camg than anything else. But keep your focus on providing them optimal environment conditions 🙏

i'd be more worried about providing the right amount of DLI that your local variables allow. If it involves a 'bloom' switch, so be it. Most likely it's just a bit warmer spectrum with the bloom switch on. some people use a warm CCT from seedling on without a problem. Some of my fastest vege growth was under a 2900k light. worrying about nuance of light properites is secondary to DLI. It's a luxury you can engage in if your equipment allows it. Don't sacrifice useable DLI for fear of using 'bloom switch' in vege phase. If giving 'max' dli relative to local variables, leave it off... or, turn it on and adjust overall power to get back to 'max' DLI ... really won't matter much. you won't be able to discern the effects of a warmer or cooler light spectrum from typical genetic diversity. Heck you probably wouldn't see a difference with naked eye with 2 rooms with clones.

are they autos or photos?? Autos you can keep em on a 18.6 schedule. no worries. Photos you can keep em on veg like 18.6 and switch to flower whenever you want. To go into flower a 12/12 can work or 13/11 or sometimes 14/10, its all about the DLI. you can have a DLI of 40 on many different lighting cycles. google has a nice blurb on DLI if you new to it. or youtube has some bits about it. dr.brucebugbee is a good sourvce for infromation.
