Can foilar feeding stain trichomes? I have LOTS of brown trichomes at 6 weeks.

I have some Headband going right now along side some Bubba Kush. Both seem to be on par with each other and both are 9/10 week strains. However this morning I noticed that a lot of my tops looked dark. Like no white crystals. So I cut a leave off of a head and put it under the scope. Almost 90% amber... At only 6 weeks?

This is the only thing I can think might be causing this, I been foliar feeding them Snow Storm and Liquid Karma. Both say they are fine in a foliar feed but the Liquid Karma is a very dark brown where the Snow Storm is clear. After I mix it into the bottle it looks primarily clear. It is not a dark solution. But after I apply it, and it dries, could it stain the trichomes to turn dark? I really don't want to harvest at 6 weeks. They are nice looking but not beefy enough.

Anyone know what can cause the crystals to turn faster? Or if they can be stained? I am stumped.

I agree, it's not wise to foliar feed while flowering, this could gause bud rot.

Don't foliar feed in flower, maybe during your transitional week, but not during bloom.

Outdoor plants get rained on all through the flowering cycle. Key is to be sure you have proper ventilation and humidity in check. If all I had was a computer fan in a closet, I'd never foliar feed.

Headband is known for being mold/fungus resistant and I am fully aware of the danger of foliar feeding during flowing I have more than enough ventilation and humidity is in check. I actually planned to only foliar feed until 6/7 weeks due to the space in my SCROG getting more cramped and then the risk is higher for mold and other issues.

My issue was with trichomes being discolored. I've folair fed before up to week 6 with snow storm alone and never had this issue. The liquid karma is dark and I think it might be what is doing it. Under a scope the trichs look amber. Almost all of them but I used just a little water this morning and they seem to be clearing up so I guess I panicked in posting this. I just needed to rinse them off.

Foliar feeding my heads has made a huge difference. I understand it is risky but I don't soak them and a dehumidifier keeps the air relatively dry. My particular grow set up alows me to get away with it till the SCROG fills in.

Thank you all for your input. I do understand foliar feeding flowers is risky.

Their is a difference between rain and foliar fed fertilizer... But at least you understand the risks you are taking. Cheers.

I wouldnt be spraying anything on something i was going to smoke..

Is a good point. I don't do a full neut spray. Until this cycle It's only ever been Snow Storm and I would do it till about 6/7 weeks. As far as I know it is safe to use. Says on the bottle foliar feeding is the most economical. But I can't honestly say I've done extensive research into how long it takes to break down and risks of smoking it.

I guess it is not wise to just assume what they say on the bottle is infallible. And it is better to be safe than sorry. I just been going by the idea that it makes no difference in having the chemicals on the inside of the plant or out. I think I will give that some second thought.

Maybe you should listen to the advise given here because if your foliar feeding that late in flower you...my friend...don't know the risks. All this advise is solid so why come on here and not listen to the advise? Your brown thrich are directly related to the crap your spraying them with. Foliar feeding should only be used for emergencies, there are just too many issues that arise from this method. You probably have other issues directly related and you don't even know it. Ant new grows I set up I tell the clients NOT to spray any product on your plants...its too risky and why if you don't have too?... JAS

I am. The more I am reading into it here and on other pages I realize that though I am risking mold/rot and am possibly overconfident in thinking I have it in check there are other issues that can come of late foliar feeding that have made me rethink it. It can dry up the pistols and if the concentration is too strong it can actually stunt growth. I was not worried about mold because I have stellar ventilation and canopy fans. So the advise given was stuff I already knew from reading the basics. Nobody mentioned the possibility of burning pistols and stomata. I've read where you can folair feed up to 3 weeks before harvest. Of course this does not mean soaking your buds... I've folair feed snow storm through 4 cycles now up to week 6/7 with no issues. Never had a problem till I added liquid karma... So when someone says mold, I am passed that. My issue was with stained trichomes which have since rinsed clean.

It is not that I am not open to advice. Mold is just not an issue for me in this particular grow. I've tested my method and between warmer temps for maximum Co2 absorption, canopy fans, ventilation and even a small fan under my scrog, I've seen no mold in the year that I've been foliar feeding snow. If I didn't have atmospheric conditions in check, I would worry about mold. rH is always between 40/50.

But I appreciate your eagerness to get me to listen to the above posters. I thanked them but again, mold is not an issue for me or other foliar feeders who grow in the proper environment for it.
