Need flushing/harvesting advice from veterans (Bubbleponics/DWC with LED lights)

I'm not sure the trichomes are withering. They almost look like they're just getting touches of color, which isn't necessarily a bad thing, in fact some people like hints of color. The actual heads of most of your trichomes still look clear, and that's what's matters. It's odd your trichomes pictures are seeing the trichomes from the side, can you get any trichome pictures looking down on one of the buds (not the sugar leaves) so we can see lots of trichomes from above? Also, could we get a picture of the plant in the setup under natural light, as well as a closeup of one of the buds? It can help us get a better understanding of the current stage of development, since each plant is a little different!

Thank you NebulaHaze. I'm having a heck of a time getting decent pictures, so I'm not sure how helpful these will be. I'm also starting to get uniform small brown spots on fan leaves and slight upward curling. Also noticed my stems are super purple, so I'm worried that I might be experiencing a cal/mag deficit, most likely due to pulling back too far on the nutrients (since I thought I was closer to harvest than I was and my leaves were super green). I'll try to get some better pictures, but this was my third try. :s

Additional pictures were taken today. I did some much-needed rearranging, moving my carbon filter that was taking up a lot of room. Still had a heck of a time getting decent pictures. I think the reflections off the mylar wash everything out. This time I just turned off all the lights and used the flash on my phone, which seemed to work a little better, but not sure if it will be easy to see what is going on. Thank you all again for the help.

This was the first time in a long while I have been able to actually get into the tent and look at the other side. The undergrowth is quite significant. Not the main colas, but the thin ones that hang down from the lower stems. Also, everything is very purple on my single plant. Is it possible to have too many grow sites for one plant?

The buds look gorgeous

First off, your buds have a really nice structure, it looks like you've got good genetics.

I see some burnt tips on leaves, which is a sign of nutrient burn (too high levels of nutrients). The leaves are also overall dark with some curled down tips, which can be a sign of a Nitrogen toxicity. What nutrients are you using now? I also see the sort of burnt edges, which appear to me to be a nutrient deficiency of some sort, or possibly light burn or heat burn. What is your pH? How close is the grow light? The leaf with the tiny brown spots does look like a Cal-Mag deficiency, but I wouldn't add Cal-Mag this late in the flowering stage since you're so close to harvest.

I can't really see the trichomes clearly, but by looking at the buds I'd guess you're almost there!

I don't think it's usually a matter of there being too many bud sites (though I'm sure there's some sort of limit). But I've found that bud sites rarely fatten up if they don't get access to air and strong, direct light. They also never seem to fatten up if they're located near the bottom, sides or middle of the plant. Only the buds near the top with space to themselves and lots of light even seem to get big. That's why a lot of growers will groom their plant right before the flowering stage to remove any poor performing bud sites. That way the plant focuses all its energy on the main ones that you want!

Overall your plants and buds look really good, and I think you're very close to harvest!

Update: Day 96 (almost 14 weeks since going 12/12)

Trics just won't turn cloudy. :s I haven't seen much if any, new growth at the bud sites for over a month now. I've been expecting them to fatten up anytime, but it's not happening. I can't get good pictures of the trichomes, but they are still very clear and icy, with a few starting to get cloudy (maybe 10 %) and the rare amber here and there (about 1%).

These may both be Sativa dominant hybrids, but 14 weeks? Nurse Jackie is supposed to be 85/15Sativa dominant. According to Homegrown Naturals, where I bought the seeds, the Tardis is 65% Indica dominant, but according to allbud, it is 70 percent Sativa dominant, so I'm not sure what to believe. My buds are definitely not looking like the ones they have pictured.

I was using an 8-week flowering schedule or nutrients, so I've been "ripening" for the past month. Plants are not especially happy. Still getting new fan leave growth on lower leaves, but upper leaves are not doing well. They endured 90-degree temperatures for up to a week while I was out of town and haven't grown much since then. It is like they are frozen in time! Thanks Tardis!

If anyone has any advice I would appreciate it. I don't mind continuing to wait, but at this point, I'm wondering if they are every going to mature. Thanks for any hints/tips/advice!

hey 247 the last 2 weeks is the hardest for a grower but alot of magic happens during those 2 weeks buds get really resinous they get much fatter and harder they gain alot of their weight during the last week .an old saying is that its better to harvest 2 weeks late than 1 week early.

Hi, oldjarhead100. Thank you for your reply. It's finding those elusive last two weeks I'm having trouble with! These were seedlings in December, so I'm way off my anticipated schedule. This may end up being a 6 month grow!
