New to this. First outdoor grow. Not quite sure what stage I’m at but know that flowering should start here soon. I’m in NY if that helps. Currently feeding Fox farm grow big. Looking to figure out when I need to switch to my big bud flowering nutrients. Then once I switch how long should I run those nutrients until I do the flush. Thanks for the help!!

- well indoors we trigger the plant to flower, outdoors it does it when the sun changes its patterns.
- when I add inputs for flowering or veg: in 5-gallon pots I input weekly, when switching to flower I input week prior before switching, I also have a pre-flower to ensure every box is checked. then officially switch to flower.
- I use the living soil concept, microbes' enzymes periodic table etc. they utilize organic inputs and break down everything you give it.
- you are in the VEG
- plant will stop eating on its own, but you do have to keep feeding living soil if you plan to reuse.
- salt based products in living soil ..? although some do it, salt build up is real. however, there is a level of salt in liquid fish products but minimal and won't hurt the plant and plant won't take up what it doesn't want.

I have done a DWC grow of some jalapenos and what I used was liquid nutes. Grow Big and Tiger Bloom was what I used. I used to use TERP tea Grow and Bloom until I found out it had poultry products. Started using the "BuildaSoil Way" and I got explosive growth, literally building a flower. Now that I see explosive growth I can move to the next metric, which is a monster cola.
Not really worried about yield, mainly worried about the process and performing my gear.

- Still on my first grow from bag seed, made it to the finish line and had some catastrophic issues but still managed to save, align and correct mistakes. Had to invoke some seedlings to keep going. Learning all the new gear from AC infinity led to my mistakes.

hope this helps
 
They don't look like they are starting to flower yet and it's getting a little late in the season to still be full veg, you should at least see some preflowers by now. Do they get any stray light at night that might interfere with flowering?

No stray light at all.

They still get direct sunlight from about 8:30am till 5 pm at this point and in general the suns rising at 6:15 right now and setting at 7:45 where I’m at.

I’ll continue the current feeding since your saying they are still full VEG

When should I switch to the Big Bud nutrients ?

What’s the first sign that I should make that switch ?

You'll know when you see it.
 
Those nutrients are immediately available, which is unlike organic nutrients. That's something to keep in mind.

Those plants are still in the vegetation stage, so you should still be emphasizing nitrogen. The next stage of growth will be the stretch. They can grow much taller rapidly and nitrogen should continue to be emphasized. When buds begin to appear, transition from nitrogen emphasis to phosphorus and potassium emphasis--that is, use of flowering nutrients. I increase the flowering nutrients slowly for about the first month of the flowering stage.

About the same here. Today makes 20 days since flowering started. The last 2 feedings have been on the heavy side. I feed twice weekly, between waterings. Using Tiger bloom. Not that I really need to...my garden is packed with animals and fish carcasses. A proverbial cemetery of NPK. Their big girls, big girls get big by eating a lot. 😆

About when the plant stretches and when it needs more frequent waterings would be 2 indicators.

You can always start slowly and continue to add more as they start to show bud sites.
 
I don't grow outdoors anymore, but I still continue my practice of a slow transition with my indoor grows. If you have 2 solutions pre-mixed (veg and flower) you can always mix the two at different ratios. Like switching a pet to a new brand of food. 2:1 old to new for a week, 1:1 for the next week, 1:2 for a week, then full flower nutes after that.

Edit: also how far north are you in NY? NYC plants will start flowering about a week earlier than northern most NY. It is a big state after all, hehe.
 
listen my guy, the answer to your question is this. you are using synthetic, not sure when to stop and add for the transition... Yes?

- in living soil, it is recommended to go thru a pre flower phase... there you add the flowering nutrition, you also increase lighting and gradually come up on your intended 12/12, DLI, PPFD.
There you add the PK long before it asks for it, since it takes time to break down you add and when it breaks down it becomes readily available when needed. Maybe 1 week or two maybe less. the deal is, it's already inputted and when plant needs it there's enough to get started, by then you'll see signs of flower and start your regime

* If you're concerned with going into flower and not having nutes available...consider using both just to cover the transition. (maybe 1-2 weeks) but you'll already be there (already in) since you have already put it in.

* doesn't work with synthetic? if it's not in your container/pot, the plant can't take it up

* doesn't sound right? add once and rest assured it will be in the plant.

I'm interested in how you came to the decision to use synthetic...? if I'm in a pinch and need nutes available to the plant in emergency I would use them in living soil.. otherwise, not recommended long term. imagine trying to veg with flowering nutes?

I'm still learning too but currently stuck, I have reached the pentacle of technology. I am waiting for the dehumidifier from AC infinity to come out so as to be able to finish drying and curing otherwise I'm stuck in VEG. One of my issues is training LST etc..

They are planted in Fox Farm Ocean Forest Potting soil. Currently feeding with Ocean forest grow big every other day with watering daily as they are in fabric pots. I’ve never grown before so I’m really just looking for the input on when I should start cutting back the grow big feed and switch over to the big bud nutrients that I have.
Basically what visual cues should trigger the switch ?

Ideally bud sites because that's what needs the nutes to grow.

Look for pre-flowers, specifically pistils. You will find them forming at the nodes.

you see this in dude's pic that he posted? using the system I just posted you will see a lot of this.
included is one of mine. so, it's ready to flower once there.
if this helps

Back off the nutes until you find your solution. add as needed
tap water has calcium and magnesium, stop using cal-mag and RO
yes ?
 
Hey, don’t be flushing when you’re in that soil bro, don’t be doing that ain’t no need for that bullshit.
Just go ahead and start giving the thing flower nutes when you start seeing pre-flower
