My Harlequin CBD is on its final weeks of bloom. The sugar leaves on the flowers however are drying up and yellowing, there is still about a week to harvest. The pistils are turning white → orange → brownish and the flowers are about the size of nice carrots. The fan leaves are already gone and trimmed out. Humidity is about 30%, to avoid rot no humidifier is used. Lights used are smallish china box led with spot leds supporting, 2500 lumen at distance aprox 40cm. Air sirculation is with small fan and biggish air TD-350 Silent conditioner on 100x100 tent. Nutrients are Advanced Nutrients in adviced measure. Is yellowing of the bud leaves caused by: Too much light? Too low humidity? Too much air circulation? Thanks in advance!

Those look like there done anyway. You will enjoy Harlequin. Reminds me a lot of the 70s stuff I used to get in High School.

Ok so you’d suggest harvest already? Flush and 24hr dark…? I’ve grown Harlequin earlier but with a bit different set up than this one.

Check the trichomes to be sure. That video will give you good info. Looking for mostly cloudy with some clear. Once amber starts forming the CBD is degrading. Looks like most of the pistils are now browned. I don’t see hardly any new white pistils. Based on that I think you can harvest.

I think about almost half are cloudy, lots of clears to be seen though. I think I will wait a day or to for plant to use last watering nutrients and then ditch the thing to dark. or Would bending the branches of the plant increase THC content at this point or should it be done earlier?

I think its produced as much as its going to at this point. Many of those techniques are supposed to increase trichome production. The idea is to stress the plant and make it try to protect the flowers by producing resin. Personally I am not 100% convinced that any of those things really work. After growing several clones this last year I feel genetics plays the biggest part in how much THC and resin you get with a plant. I liked the last Harlequin I grew so I put in my Veg grow cabinet and I will clone it for future plants if I can get it to Re-Veg and produce viable starts.

I was thinking of keeping this plant on grow for couple of days to clear up the nutes before cutting. Any sense in that? Specially if nutes are the reason why the sugar leaves burned. :frowning: I have also desires to re veg this plant. Any tips on how to proceed with Harlequin other than 24hrs light? How many flowers % I should leave on the plant for it to survive the cut?

Lots of debate on flushing and if it even works at all. Its illustrated sometimes by showing a plant the food coloring is added to the water. The color will travel up to the leaves and flowers. By simply watering with plain water the food color stays no matter how much you try to flush it out. But theres no point feeding a plant you are going to chop in the next week or so. Why waste the money on food. To reveg just place back under 18/6 light

How many “blooms” and branches I should preserve on the Harlequin plant to allow reveg?

I just saw a post this morning showing a stump that was revegged. It just had a few small buds on the lower area. I am looking for a thread with more info…

[image] Any idea what’s going on Troubleshooting Nope and yep. I do reveg on purpose. [IMG_2347] [IMG_2393]
