When is the Best Time to Harvest Marijuana Buds? | Grow Weed Easy

[Bluey]

A few more weeks

[realhuuuman420]

Well, a lot of the trichomes are milky, and more are turning milky day by day! Could be also one more week, but not longer. But again, as long as it takes. If it's another 3 weeks, then that's what it is. Sure as hell hope it isn't though!!
The color though... damn. Looks like cotton candy. Makes me want to take a bite

[Rootsruler]

Lol! : )

[Gingerbeard]

I may be being baited, but I'll bite. But only nibble. Why do you think you will be ready this weekend?

[realhuuuman420]

So very close! Very excited for harvest. Hopefully will be ready by this weekend, but don't mind keeping it for as long as it needs. And then the real battle of drying and curing starts!

[realhuuuman420]

Beginning of week 7 :O looks like 1-2 weeks until harvest!

My recommendations were for photos of course. I missed the bit about autos.l so my nute tomongs don't apply

[Gingerbeard]

Bluey ... realhuuuman420 is growing auto. Your recommendations for when to start calmag and bloom nutes are for fem.
I'm going to respectfully challenge or question what you said based on me growing autos in coco with the brand nutrients I use. I've been harvesting at 10-11 weeks. Lady bits can show at 3 weeks. At 4 weeks I add half bloom nutes to the full veg I've been giving since the 'sprout phase' was over. Next watering is half veg to full bloom. Full bloom from then on. From sprout to harvest, if I use nutrients, I use calmag.
So much respect.

All what I have grown outdoors was regular seed.

Indoors a mix of regular and fem and only a four autos to date.

[Gingerbeard]

Bluey you grow fem, yes? Not auto?

[Rootsruler]

Agree with Bluey

[Bluey]

I start calmag about 4 weeks into veg at half strength growing in coco or as soon as I see pigment loss as we did with yours.

I typically don't start bloom nutes until I see flowers, so we'll after the stretch, but sometimes I start early depending on the colour of my leaves looking at the plant from bottom to top. You can often see how much N is present in the plant and at what level it's packing it into the leaves.

Look closely at your leaf tips for browning off or a folding in of the leaf outer.indicating the start of nute burn. Try to keep your nutes balanced, not more of anything. You can't make up fior something that wasn't there earlier when it needed it nor can you remove something it didn't need later so small adjustments to correct problems.

I suppose the below simply confirms what you are all saying anyway - CalMag deficiency, started feeding too late, and ofc those watering issues I pointed out as well.

Still wanted to detail this in case there's something terribly wrong with the feeding - especially the CalMag part. Should I give a bit more, say 1.2 ml / L, even if BioBizz says max 0.8ml, to compensate for the lack?

I have been giving it CalMag starting with my first feeding, but clearly not enough. I started under half of the recommended dosage according to the BIoBizz chart, and steadily increasing to 100%- https://www.biobizz.com/wp-content/u...le-EN-2024.pdf

27th of Oct: BioGrow (0.5ml), BioBloom (1ml), TopMax (0.5ml), CalMag (0.3ml)
31st of Oct - Bloom (2ml), Grow (1ml), Max (0.5ml), CalMag (0.4ml)
2nd of Nov - Bloom (3ml), Grow (1ml), Max (1.5ml), CalMag (0.4ml)

Today will be the 4th feeding, I planned to up the dosage all the way up to 100% of recommended, meaning BioBloom up to 4ml, and CalMag of 0.8ml per liter of water. BioBizz recommends using BioGrow throughout the entire grow (starting at around when soil starts to cool down), at 1ml per liter of water going in.

And something that keeps bugging me - this needs to be a lesson for my next grow. So, in retrospect, should I have started feeding as soon as I noticed the slight pigment loss? If yes, then this would be a clear and hard to miss sign, and next time I will be able to understand what the plant is trying to tell me.

[Bluey]

The calmag you add if in liquid form will likely be nitrate based which it will draw N from but check that, that's why you don't want to be adding it too far into flower, too much N.
