Flipped under 10 hours of light…

So I think I already know the answer to this question , but I am about 3 weeks into flower and noticing some slower bud development than usual.

Today I checked my outlet timer and it appears my light schedule is less than 10 hours on .

I have been growing for a number of years now and never had this issue , I figure it is probably too late and risky to bump up the light schedule to 11 or 12 hours on without causing an issue , but this yield is seriously going to suffer .

Has anyone experienced this before and added more light (still under 12 hours) while their timer has been wrong ? Obviously main concern would be causing a reveg or herming .


Let me know!!

No issue. If you're scared bump it by 30mins every 3 days, or a few mins a day which won't 'shock' the plant if that's what your worried about. (It won't anyways)
2hrs a day wouldnt cause very noticeable slower bud development over 3 weeks. If you look at it by the dli, you'd only be about a day and a half behind.
Plants won't reveg under 12, even up to 14 hrs of light. 12/12 is just a general photoperiod where 99.9% of phenos will flower without fail. (don t quote me on that %. Lol). They will still flower under higher light hours but every strains diff and you can find the Google pic of the difference in light on the same plant. Less hours more compact more hours less compact and more stretch. At least that's how I remember it. The pic is floating around here somewhere, people have posted it before.
