Last 7-14 days of flower, should I continue giving them nutes (pictures inside)

[Dicomaco]

So I'm in the last days of flowering, except for a thrip attack, everything has went well. Now I'm closing in on my only 2nd big harvest ever and I'm getting a little uncertain about a few things.

As you can see on the pics, some of the leaves have started to curve (I don't think it's heat as they started doing it recently), and some of them 'appear' to have a little nute burn on them, although nothing major.

My first question is, if most of the thricomes look milky, should I still continue giving them nutes, or should I start flushing soon... and should it then mature further and become a bit amber during the last 7-10 days of only watering?

Also, if I see a bit of nute burn, should I lower the dose, or just follow my programme and give them full strength? I heard that it's better to do a little overfertilizing than the opposite... I just don't wanna risk burning off my buds!

My strains are: Chronic, White Russian, Cole Train, and a single Chocolope (I know she doesn't fit in the mix ) So if anyone have experience with some of the strains I'm open for recommendations, I realize that all strains/phenotypes behave different

Light: 600w Sunmaster
Soil: Coco & soil mix
Nutes: Advanced Nutritions (Grow, Micro, Bloom, Big Bud, Overdrive, B52)
Vegetation time: around 8 weeks
Flowering so far: 7 weeks

And yes the fan leaves HAVE started to fall off, been doing so for a few days now, just a few at a time.

Appreciate any help!

Cut the nutes off for the last week. Just add pH adjusted water and let them use what they have stored in the tissue of the plant.

i personally give a 2 week flush with plain water and mollasses.
i cut off all food 14 days befor harvest.

only thing i would reccomend feeding them those last days is the molasses , which has the sugar and carbohydrates that the plant loves for those last few days....

good luck

If you are on week 7 now (and are planning on taking them 9 weeks), then you should begin flushing now, or within the next week. Don't give them anymore food.

 

[Dicomaco]

I don't know why it won't let me attach the pics, will try again

 

[Dicomaco]

Good advices thanks. Well I just counted the days and it says 55 days in. Most grow reports on Chronic say 65 days, so I guess I should start flushing. I'm hesitating a little because the biggest one looks like it's a bit behind on maturity, having many white hairs, but I guess I can just fertilize it for a few days more then and flush the rest now.

At what point should I start using molasses, already after first flush? Also how many times do you guys flush? Last time I did one big flush and then just pH watered the next 7 days, followed by 3 days of no water (to dry) until I chopped them down..

Is it true that I could use whole sugar instead of the expensive brand molasses stuff?

 

[Guest3498]

No problem at all.

Don't worry about the white hairs, that has more to do with how long it's been in flowering and less to do with food. At this point with most strains giving them more food does not equate to bigger buds automatically. That stage is pretty much over for them, now they are just finishing up and ripening.

Your main goal right now should be the opposite of giving them food - You want to starve them. Yellow fan leaves all over are ideal, not green ones.

How much extra do they usually grow/mature after discontinueing nutes? I just need a guideline so that I got an idea of how much they will mature during the last 10-14 days, compared to their current milky trichomes (75%, I don't see anything amber really). Obviously I don't wanna start flushing them too early

You will seldom have a plant indoors in soil that is over flushed. Just the opposite is usually the problem.

I use clearex every other watering during the last two weeks. Even then, its not always enough, imo.

Btw, I like mature weed, so I look for about 30% amber trichs.

And I don't believe in flushing with molasses. That isn't really a flush, imo.

This info made a bell ring, I completely forgot to take into account all the stored nutritents in the leaves, and in fact only few of my plants leaves are yellowing, most are still full green!

I think I will give my Cole train (she eats like crazy) and bit more, and then flush the hell out of the rest.

Awesome reply, appreciate it!

^^^^^Agreed, molasses is sugar = feed

You're trying to get the plant to 'flush' out it's own food and loose the N in the process, in soil just water is OK

Hydro benefits from a proper flushing agent IMHO

Could you elaborate on that? Do you mean that the molasses have an impact on how the buds taste, so you consider it not being a complete flush or?
It seems growers are 50/50 on the molasses subject, I guess I gotta try it for myself in order to judge

About amber trichs, how many % amber would one grow a typical hybrid like Chronic, if it's not supposed to become too couch lock smoke?
I realize that Chronic is more indica dominant but I decided to grow it because a friend said it was relatively easy and good for a novice grower. (he was right )

to each there own. but these buds i flushed with molasses has INCREDIBLE taste. and burns to a white ash.. more flushed then anything ive ever seen in a dispence.

I will definitely give it a try in the future, appreciate your input!

molasses is a source of food for the soil, particularly cal/mag along with some other nutrients. it is said that it helps 'smooth' the smoke out so it's not as harsh, but when your bud burns to a white ash it's not due to molasses - it's due to flushing all available nutrients from the soil. black ash vs white ash, to my knowledge, is when there are left-over elements in the plant (nitrogen, etc.) and white ash normally comes when the plant was properly flushed. if you are flushing with molasses-laced water, i think the shear volume of water is washing away the undesirables and the molasses may assist with the taste/smoothness of the smoke, but i highly doubt thats' why the plant burns to a white ash.

 

[trichrider]

hmnn. does molasses impart a 'flavor' to the final product?
not sure what would give you that idea. load a bowl with sugar and take a nice long draw, now when you stop choking, does it taste sweet? hmnph.
application of molasses is for the microherd to feast upon as they colonize the root zone, early...before flowering.
now i admit i've flushed with it, but cannot attest its efficacy.
stop feeding, water with plain h2o, and make a mental note of the color of the trichomes when you chop. after a few times you will know intuitively when to reap.
good to grow!

ya. i never ment that the molasses itself is flushing the plant out. i was just saying that if you use it in flush stage it helps with over all smell and flavor! and out of my 7 years growing i can def say that it is fact! at least for me. since i started doing this my buds taste and smell are way enhanced! and did i mention smoooooooth!!!
thanks for the response , happy gardening

^flushed with molasses for 14 days.

 

[DankByNature]

Molasses is used to feed the microorganisms,which then excrete a more useable form of food for the plant. Highly doubt that adding molasses will have much affect on the smoothness of smoke, however it may aid in synthesizing the remaining nutrients in the soil (ie. flushing/using remaining nutes). It obviously won't hurt the plant, so it is up to your discretion. Definately would not add anymore nutes.
