New grower advice

I have 2 autoflower blueberry and 1 northern lights auto and they are on day 67 of 70 expected. They have barely begun to bud. Can autoflowers take longer than there expected flower time? This is week 10 of 8 to 10 expected.

Hey there........everyone has their definition of "barely begun to bud"...... ;)

We could use better pics, sometimes it's hard with strong lights on, but they look like they're budding and in full bloom to me. You might be looking at more than 10 weeks though, it's not an exact date. You want to give them all the time for maturity they need. But they look fine from this picture.

What's your light cycle and what kind of light do you have? And how many days has it been since they started to flower?

18 6 and I have a 600w vivosun about 18 inched from canopy

All "flowering times" are subjective... my grand daddy purples take 8-10 weeks to flower but this monster took 16 weeks to flower! Best way to tell if harvest is ready is to get a microscope or phone camera and look at your trichomes. You'll want cloudy to amber heads

The light cycle is fine. I can't tell if the light needs to be raised, that might be too close, but in terms of the flowering cycle they seem fine to me.

Looks fine to me. Let 'em keep flowering, and eventually ripen.....

Are these Autos?

18 inches away, 600w wow what is your ppfd readings at top of canopy, I have a sf 1000 (100w) and have it 25-30 inches from canopy and I'm getting 600-900 ppfd. There is an app on the app store called photone it allows you to get ppfd readings with your phone camera. Too much light will absolutely slow growth in flower.

After relooking at your picture I see some tips curving upwards, some leaf tip burn, my guess is it's too much light.

I'm guessing he's at 900-1000 at 18 inches

Yes currently in week 10

Thank you I'll check it so I'm guessing 600-900 is optimal?

Yes I have some curling and I believe my northern lights auto is developing a deficiency but I don't know what

For normal growers (like myself) who don't use Co2 during the flowering stage ..yes. I would push that to 750-950 as optimal. And certain situations will dictate how much your plant can handle too. Environment, nutrient regime, lighting schedule, can all effect how much PAR your plant can handle. Just watch the plant, it will talk to you. Especially towards the end of the lighting schedule, sometimes your plants will start drooping 2 hours before the lights go out. A good sign to lower the par a little. Some start low and gradually increase it by week.

edit: Just noticed your running an Auto, so DLI would be the more important number. Lot to take in for new growers. Took me a freakn year to understand this all (I personally play it safe for a target of 36) if you know what your doing with the soil, lighting, and nutrients then go for it up to the 50's

My ppdf varies through out my tent but does not reach 750 should my camera be facing the light to test it?

750 at 18 hours on for an Auto would be PLENTY, set it and forget it

Your front facing camera the one you take selfies with, place it on the head of the plant point camera towards the light and see what it reads.
