Yellowing leaves.

[nicandy]

High everybody! (Dr Nick would never say it that way!)

I have some yellowing leaves on my little darlings. The yellowed leaves are mostly on the lower end of the plants and getting gradually rarer toward the bottom of the buds. I know its getting near chopping time (three weeks or so) and I wonder if I should just let it go and hope that it's just the time of year (days are getting quite short, up here in the Great White North!) or try a bit of chemistry to try and bring back the nice green shade they should be.

I have cut-and-pasted the troubleshooting guide (Thank you Stinky, nicely done, a great guide to use) and tried to answer all questions. These plants have been started from seeds in the spring, kept indoors in a south facing window and planted outdoors sometimes in late May, early June. The picture was taken today.


Soil type/brand: outdoors (garden) grown, traditional soil
Anything you have added to the soil: compost
Soil or slab runoff pH: unknown
Water source: rain and tap (city) water
Age of plant: near complete flowering
Type of fertilizer: fertilizer 20-20-20 (bi-weekly, dosed as per package instructions) during the growing season, 15-30-15 (weekly, dosed as per package instructions) during the last three weeks.

The five below are all self-answering, considering the plants are grown outdoorsâ?¦
Lighting source and distance from plant
Air temperature (both day and night if you are running a dark period)
Air % Relative humidity
Lighting schedule
Type of ventilation your room has

You can increase the N you are feeding them but it probably won't really matter if you're that close to harvest. Just about every plant I harvested had yellowing leaves 3-4 weeks before being picked, some more then others. As long as the leaves around the buds look good you're ok.

That's about my way of thinking too. I'll just leave them alone and keep a close eye on them.

Thank you,

Try adding potassium.
