Hi, This is my first grow. I’m growing indoors, I’m 15 weeks into my grow, about 8 weeks in flower. This is a sativa strain. I started my final flushing about a week ago. I’ve not had any insect or disease problems to this point. Now I’ve found a couple of the sugar leaves that have brown spots starting on them. The plant and bud looks good in general. Is this just stress from lack of nutrients, or am I about to lose the plant?

Welcome to the community @KDB5716
Your plant is beautiful. I think you have a few weeks to go yet. Lots of white hairs. I will tag some very knowledgeable people to give to advice on the spots and the harvest time. @kellydans @Lacewing @PurpNGold74 @Mr_Wormwood can y’all give some advice here?
Thank You

I dont think your neer flushing time yet. Looks to me you could have 3/5 weeks left. She’s got a lot of bulking up left to do. When those white hairs turn reddish and shrivel up back into the bud, then start looking at the tricoms.

Yup too early on the harvest trigger. Most sativa leaners flower longer then other strains. Alot going 12+. Some going 14-16 weeks. Id let her keep flowering.
And the specs look like cal deficiency. Have u supplemented any calmag?

Thanks PurpNGold74 . I didn’t have any information on actual growth period for this strain. I got the seeds given to me. So then I’ve probably misjudged when to start the flush, and that would explain the deficiency. I was using Dyna-Grow Bloom fertilizer. I can get some calmag as well if you think I should keep fertilizing for a while. Soil grow by the way.
Are you saying 12-16 weeks of flowering stage. or total age?
Also, the previous bud photo is the main cola. Buds in the next level down do have the pistils browning off some. Judging 2 weeks before harvest for flushing is a big guess for me.

Thanks Flitme. Appreciate your nudge to the others with my question.

Thank you Audiofreak…so much to learn. Timing is everything as they say. I’ve been watching the trichomes for a couple weeks, all still clear as far as I can tell with 30x loupe. Anxious first time father I suppose.

I agree with the other members you still have away to go and being a sativa they usually flower longer aswell

No I was just saying there are strains that can go that long. Judging by trichomes (on BUDS not sugar leaves) is the only way to be certain your weed is ready for harvest.
Typically my trichs dont get cloudy (let alone amber) until the pistils (hairs) have all pretty much gon from white to amber first. Then the calyx (single buds, look like a triangle with the 2 pistils sticking out) will begin to swell up. Then the trichs mature (from clear to cloudy/milky then amber for the couch lock effect).
I think youre looking at another month or so of growing. So a few nutes wont hurt. But u dont wanna overload her neither.

This is all very good information that I can use for this grow and future ones. I really appreciate all of you weighing in.

Nice job so far but you’re nowhere near time to flush. You want to wait until nearly all the pistils turn brown and recede back into the calyx’s then start checking trichomes for cloudy to amber. By then those buds will be a lot bigger and fatter. I’d say you got at least 4 weeks maybe even 6 cuz it’s a Sativa.

That’s a cool lookin plant. You got some great advice above. The best part is that sucka is gonna bulk up big time!

Dito. White pistils are a sign that the bud is still growing and swelling. When it’s time to flush, all the trichomes should be clouded (at the very least). The pistils should have turned and shriveled at that point, showing that bud growth has basically ceased.
As for the leaves in the bigger pics of your plant, the burnt, crispy ends, that looks like nutrient burn. The damage had likely been done before you began the premature flush and took a little time to show. Leaves don’t show damage right away, so they likely were displaying stress from conditions a week or so before (or were they burnt before that?). Moving forward, a quick mid-flower flush, and a check of your runoff to get the ppms in the medium right should prevent further stress. A lot of people go too hard on their nutes. I personally never go above 900 ppms (EC of 1.5) and have never had problems with deficiencies. Unless you’re supplementing CO2 in your grow, there’s no need to push the nutes so hard. Plus, when the TDS gets too high in the medium, certain nutrients can get locked-out, causing further problems. I do a quick flush about every 3 weeks, (coco) just a couple waterings with very low EC water, then check my runoff to make sure I’ve flushed some of the build-up. Other than that, the plant looks nice.
