Jack Herer Auto

[PVCPOT777]

Fellow growers asking for help/opinions.

I am on day 75 from germination. I'd like to know when is it actually harvest time? The buds seem to have slowed down. I compare pics from past days and they seem to be bigger but nowhere near what I have seen as an average.

3 gallon fabric pot
Ocean forest soil
RO Water with half dose cal mag every time. ph 6.6
light was 18/6 until 2 weeks ago I changed to 14/10 (thinking it might have changed the results)

I have not done a flush yet since the grow started, just fearing root rot.

Thanks

More dark pistils than white ones, cloudy and amber trichs. But why the light change?

[Catfish22]

Day 75, wouldn't that soil be getting a bit weak?

Also that close up has a lot of white pistils and few trichs. The JH I've seen is covered in trichomes. I say you have at least 3 weeks to go.

Don't know why you change that light cycle, not good move for auto flowers who love long warm days?? It looks like at least 35days to go at that lighting and no other food.

90 days from seed to harvest like Northern Lights autos.
depending on grow medium and indoor/outdoor grows and light cycle

[PVCPOT777]

I did read somewhere at the time and others had changed the light cycles because they were also running into this issue.

also many sites say 60 to 70 days for harvest, but this might be an odd case.

I will switch back to 18/6 tonight. And keep you posted.

good point on the soil being weak. Every 2 or 3 watering I will add 2-8-4 at half dose

Update:

Here is something new I noticed today.. two of the sugar leaves turning dark.

[Puglover1]

Do you mean the purple leaves, or the brown spots on them? Not sure, but you might be skimping on the nutes at this stage, I've not used your soil before.

[PVCPOT777]

Are the purple leaves normal?

Are the brown spots due to a deficiency?

[Puglover1]

Purple happens, yes, I like purple. The brown spots someone more experienced will have to weigh in, sorry. I like smoking Jack Herer for pain but I haven't grown it.
