Yeah thx, I've grown 1200 at a time but I'll make sure I listen to you
What's your late flower nutrient regimen?

Moving along quickly. Here's some I made earlier
About 5 days before flower, I started to top up with bloom food. That's about 20% of the tank each day. The bloom is 215ppm-N. In the first few weeks, I might of double dosed the N&K topup value a few times. As the new growth showed that the leaves were probably being called upon. This was measuring about 2.2 The two or three tank changes through bloom were a bit rich though, as they took their fill. I use hardish water, which is adding to the EC measured, more each day. So when I drop a 2.2 tank for a fresh 2.2, the new tank is hot. The old tank would of been getting them N&K double doses though, as they do get taken very quickly. Double dose is straight from hydro tomatoes.
Just after peak flower they were still green, so I dropped to about 180iirc. Then 160. I never saw any signs of the leaves being used, anywhere.
This is probably as high an N as I would want. Some look at those buds and say it's too high, but my tongues smacking my lips with that presentation.
If I'm at 240N I have real problems. This 215 is showing on them, where susceptible.

When there’s clawing because of too much N it isn’t even mild over feeding any more, it’s a proper one.

Grown in hastily prepared multipurpose compost with a fair bit of seaweed amendment (unmeasured) and then fed with chemical fertilisers - Formulex GT at EC 1.5 from week 4 - 6, then GT + MPK at EC 1.5 week 7 - 10 -then plain water . The plant lived for 75 days in total
I think I may have overdone it with the seaweed and there there is also feed in the compost.
This was the plant a week before harvest

GT singles for bloom.
Soil 1.4-1.4-2.6
Coco 1.5-1.4-3.1
Formulex 2-0.9-3.3
Hydro 3.1-1.9-5.9
Formulex is good for cuttings, but not many people buy a feed, just for cuttings. Though it does come in 100ml bottles. While the rest are 1000ml+. So they do know what it's for.
The soil and coco feeds have the lower N, as it may accumulate. This is more likely in soil, where runoff isn't as common as in coco grows. The K is usually near double the N, as N antagonises it. Here the Formulex is behind the bunch. It's the P that's most interesting though. In the soil and coco feed, N and P are similar, but in formulex, it is half.
I have never heard strong claims regarding Ks effects, but those that flowered with Formulex all found the N too high. Even in hydro. The P&K were just too low, without using more feed, which was then too much N.
You have your MPK to fix this pretty much. You might start using it earlier though. Your pic I commented on, has a kind of jade green. The hint of blue, that tells us P is low. It's not present in the last pic though. So maybe it's just camera lighting

I just run maxi grow and Bloom 50/50 until week 6 of flower with calmag. ( Promix)
Drop the grow and use maxi bloom with floralicious until week 8 and water only with runoff for two weeks before harvest.

I'm in RDWC. I just let my nutrient strength drift down by continuing to add water and a little bit of mag sulfate (epsom salt). That way they still have access to most of the nutrients. Since plants pull N out of solution the fastest, this accomplishes the goal of reduced N as well.
I think going to zero nutes is an unnecessary and undesirable shock to the plants and stunts the finish.

Do you start your bloom nutes at day 1 of 12/12, or do you taper from veg to flower during stretch?
That's what i do in soil.
First week of 12/12 it's just small amount of Bloom on top of veg feed. 2nd week i have little less Grow component in the mix but it's still almost as strong as the vegetative feed re N.
After the first two weeks i start gradually dropping the N every week and upping bloom nutes

Reduced N during the first two weeks of bloom, steers them into flower quicker. This suits most peoples grows. After stretch, increase N to flowering levels.
High N during grow will get them through this, while still letting them see food is running out.
The switch to bloom is adequate, without the above
A transition between feeds is good, to build big plants through transition.
This ethos ties in with longer days than 12h.
Keeping on veg too long will drag out transition too long. Giving a slow start to flower, but won't prolong flower enough to win it back. This need for growth really wanted more veg time, or longer days. Longer days will lengthen transition as high N will, but also delay the finish, to win back the losses + gain some
There is a range of methods, but most people want to get stretch over with, as it's hard to gauge in advance. Making the switch to bloom on day one, the general choice. Without the complication of dropping N even lower, as lifes hard enough as it is

I've been using GH MaxiBloom for a few years so I'm using the same nutes in both veg and flower. I just lower the EC towards the end. Makes things simple and easy. The plants don't seem to care. They're getting everything they need.

5-15-14 looks toxic.
To get 200ppm N, you end up with 260ppm P. The window is 40-80 with losses outside of this. This food must be ancient.
Our plants are fairly good at refusing it, and moving excess to the roots. Protection methods they have to employ. So it won't kill them.
Oddly enough, it might kill us though. It's a major cause of river pollution, and has a finite supply that has implications we can't manage. Today agricultural methods are pushing towards unlocking P in the ground with plant acids, as conservation efforts are needed right now. So this feed is lowering yield with a bad tasting over supply, leading to food scarcity. This needs looking at. This needs banning.
Edit: The maximum P needed by a plant in a study, was 90ppm. An outsider. This plant produced 80% at 40ppm. The 260ppm number is truly astronomical. From the last century. Toxic is the right word

Id cut the nutrients back 25% 2 weeks before harvest, then on the last week, I would cut it back another 25%, for a 50% total reduction, the last 2 weeks.
I also use AZOMITE, for Micros/Trace Minerals.
