Welcome to ILGM forum. You are only 7 weeks, she has a ways to go. I just grew some NL autos that took a while to start frosting up. Your patience will be rewarded.


I’ve only done a handful of grows myself, but maybe you should check the P & K content of those nutes with a testing kit? Could be that the plant is having to burn all her energy just to grow pistils and calyxes but doesn’t have enough to produce trichomes. Also…what is your current lighting schedule? If it’s an auto, you are severely shorting your potential quality and yield if you give them any less than 18 hours light. Just my experience, but I would ask someone with more experience before acting on anything.


Yeah lighting schedule 18 on 6 off since seed dont know how to check the levels on that one I may just buy more nutes and molasses and try that

I’m having the same problem. No trichomes. With other grows, I usually see trichomes on the buds at least at this stage of flower.

@Cj1511 looks like signs of nute burn on some of those first pics (burnt, crispy tips & leaves starting to curl up at ends). Might want to contact one of the walking grow bots here such as @Covertgrower or @dbrn32 because they have FAR more knowledge than I do. For now, I would only water when needed, and I would cut nutes out completely until I discussed the issue with one of them. If they aren’t sure, they can put you in touch with someone who may be able to help, most likely. Here’s hoping for the best! :pray:t3:


Welcome to the forum community! @BipolarPanda a lot of times they don’t pack on trichomes until a little farther along into flower.


@Cj1511 Just curious… is that a hair in pic 4? Looks WAY too long and thin to be a pistil

Id assume its a hair as far as what im doing now at 8 weeks 3 days im ceasing all nutes and just going to flush at week 9 or in 4 days and probably run it to week 11-12 if nothing then I’ll sadly harvest as plant seems to be dying ive had to take off a bunch of leaves due to yellowing/dying and its still happening so yeah

@BipolarPanda yeah I’ve tried molasses and a light increase helped with the smell thing not so much on the trichomes however I’ve been reading about uvb lights apparently it can be used to induce trichome production/stress them in the right way so they produce more trichomes havent tried it or experimented but lots of info about it online

@Cj1511can you see any of the roots anywhere? Just wondering if there might be any rot or other root issues? Looks similar to a plant my buddy had go bad due to rot in mid-late flower years ago

Some of top fan leaves have gone yellow now ive stopped feeding im.assuming it’s normal and that its sucking the nitrogen out as the buds are starting to pack on some real weight to them now the only root a see at any point is the top feeder root which is nice and healthy looking its the only root I can see when I water it so I put some more soil around edges/plant base id say if anything its root bound and next time to offset that ill be using 5 gallon fabric pots

I’m having a similar issue with ILGM Wedding Cake autos. Gals have made tons of flower spots, but aren’t frosting or fattening at all. I think patience is best advice.

I don’t recommend switching to 12/12 cause it just shocks em way too much. As someone else mentioned, UVB light is supposed to help with that. I wonder if a UVB lizard light on each side of a tent and a daily quarter turn would make a difference. With winter coming, it’d be a good time to try that. I’m just sayin’

Marijuana plants have a unique smell and taste thanks to the terpenes, the chemicals that produce their aroma and flavor. But terpenes are also affected by different factors in the environment that can change their quantity and quality. One of these factors is heat. If your tent is too hot, the terpenes will vaporize and the smell of your plants will disappear. Some people may prefer a low or no odor, but this also means a lower quality and potency.

If you want to enhance the smell (and taste) of your marijuana buds, please check out our guide on how to improve the taste and smell of your marijuana.
