My general observation is that you dont want to change your vegetative nutrient ratios until after week 3 of flowering
Bingo brother… about the only ine i know is dynagro … even the president said they only make a bloom line because consumers demand itYou don't see this reiterated too much.
I've always kept up my high N nutes through flower, just with gradually less frequency as they reach the finish line.
IME, Grow and Bloom formulas both have what it takes to carry a plant to harvest, just not optimally. And it seems the optimal mix is for some reason not solely found in one formula*cough*.. $$$... *cough*
Because customers don't like waiting an extra 1-2 weeks for the buds to finish.Bingo brother… about the only ine i know is dynagro … even the president said they only make a bloom line because consumers demand it
Yeah thats also something i dont get for the most part. I mean i can see the need sometimes but imo its ready when its ready. But they can also reduce the nitrogen while keeping the same ratios by reducing the concentration…. While i feel a slight benefit to a small ratio change i am avidly against the notion they need to change as much as the fertilizer companies would have you believe.Because customers don't like waiting an extra 1-2 weeks for the buds to finish.
I have a clone; I just harvested the original using bloom only. This one I'm doing 50-50 grow/bloom to see if I can extend flower time. The next time maybe I'll do grow only.Yeah thats also something i dont get for the most part. I mean i can see the need sometimes but imo its ready when its ready.

Id be interested to see what you observe… if you do tag me if ya dont mind?I have a clone; I just harvested the original using bloom only. This one I'm doing 50-50 grow/bloom to see if I can extend flower time. The next time maybe I'll do grow only.
You have more than an N issue. See the little rust spots starting to form on light leaves. That is a calcium Def. You will need to increase the Calcium as well. To increase calcium you have to also increase Magnesium. They do not play well togetherView attachment 1281738
it's most pronounced on that leaf right there. those are two different plants btw, the one on the left and the one in question on the right
but if you look here you can kind of see the lighter shade is more pronounced throughout the entire plant
View attachment 1281741
see how the plant on the left is a darker almost forest green kind of colour whereas the plant to the right is almost lime green?
Okay you gotta be straight with me dude. I have been told REPEATEDLY by many different folk that I need to DECREASE the N, almost to zero, because in flower, my plant is using extreme amounts of P&K. Which to me made absolutely no sense. If N is responsible for dense foliage being produced, what produces the buds/flower pistils? Unicorn farts?You don't see this reiterated too much.

I did observe that. Tbh, I think it might've been because my growlight was a little too close to the plant. It was at 100% and like, 2-3 inches away from where that star was.You have more than an N issue. See the little rust spots starting to form on light leaves. That is a calcium Def.

Nitrogen is still needed for the creation of any new cell and the plant is just physiologically still in veg-mode for the first weeks after flip.Okay you gotta be straight with me dude.

To me I always thought N was the most necessary nutrient in flower, but I've never grown before. Just from reading and researching, I've always wondered this.

But regardless, I was planning on making a calmag concoction of epsom salts and egg shells. How many egg shells do you think I'd need to be added for 1tbsp. of epsom salts?
You think my plants need some of that good ol' sulphur, eh?Nitrogen is still needed for the creation of any new cell and the plant is just physiologically still in veg-mode for the first weeks after flip.
Some up the N here to throttle it down to half around mid-flower. Lots of it is dependant on your growstyle.
The plant right could use more N, S in my opinion. It's N & Mg that contributes greatly to 'leaf greeness'. Chlorotic yellow leaves typically indicate such a deficiency (mostly N).
But it's really hard to bring this topic up ("N in flower") because most think it's not needed. It is one of the most prevalent myths in the grower scene
It doesn't make do without it. It will suck it from the leaves. I posted this earlier but deleted it because it doesn't give a ton of info. You might get something from it though: Link: WHY MARIJUANA LEAVES TURN YELLOW DURING THE FINAL STAGE OF FLOWERINGYou think my plants need some of that good ol' sulphur, eh?
I'm not here to argue against anyone's opinion, I know nothing. I just never fully accepted that a plant in flower could make do without N.
And I watched that before you deleted it lol. Ty for sharing. A lot of misinformation being passed around in certain cannabis communities. Have I finally found a true and honest forum to participate and learn from? Thank God for the farm lol!It doesn't make do without it. It will suck it from the leaves.

in flower we want to adjust Mg & S a bit higher.You think my plants need some of that good ol' sulphur, eh?

Dude, I could've sworn I had BOTH a mg and s deficiency early on when I first transplanted (you can go look at my grow diary if you need proof) I watered in 1tbsp. of some epsom salts I found in my cupboard and the plant came roaring back to life!!in flower we want to adjust Mg & S a bit higher.
S is for terps/cannabinoids
Mg compensates loss of chlorophyll from higher PPFD esp. under LED
I particularil like Eosom Salt because in the famous kation "chain" P:Ca:Mg 4:2:1 it's actually Mg that runs the highest danger of being locked out by K (excessive PK booster).
Maybe you already have read about Calmag 3:1 for Cannabis? The 4:2:1 ratio is contained within Hoagland's solution, that runs many plants. So we have proof of a working range to fiddle with nute ions, but it's dangerous due to ion antagonism, when you change one parameter - it will also change others.
So you gotta do these things at the right time as well. And get to know what your growstyle already brings to the table, and what is best to fill in the empty spots, if there are any.
You're gonna run into a lot of controversies with a culture whose practices have been largely kept out of conventional study.Okay you gotta be straight with me dude.

my bad, that "P" needs to be a "K". Got my brain wrapped around "Potassium"...P:Ca:Mg 4:2:1
"plants can only take up nutrients in ionic form which basically means thay must be dissolved in water. "Almost all synthetic ferts are salts… when they are broken down into ionic form (dissolved in water) they are no longer in salt form but ions…. Eg nitrate Sources can come from calcium nitrate, potassium nitrate etc etc etc. basically a nitrate is a nitrate no matter the source it came from.
eg. calcium nitrate dissolved break down into seperate calcium and nitrate ions. This is why several different sources are used in making fertilizer to get the ratios we want.
plants can only take up nutrients in ionic form which basically means thay must be dissolved in water. If they precipitate out as or remain in mineral salts form they cannot be used by the plants.
Thats how organics work. some nutrients remain bound as solids and are slowly broken down over time into mineral salts and then ionic form which plants can take up.
This is where CEC plays a role in the media for storage of nutrients long term

I think he was referring to fertilizers that utilize salts only."plants can only take up nutrients in ionic form"
This is not correct
