Phosphorus deficiency?

4 weeks into flower thinking phosphorus def do to over watering ??
plants will use up more nutrients during flowering. Phos being 1 of those. your right in the middle so if their healthy they should be eating a good amount of nutes. this is 1 of the reasons i try to run my ppms a little higher just so i never have to chase it. Phos is super important during flowering

What @H.A.F said. we need more information. Whats your ph Whats your ppm coming out to? Where were those leafs pulled from the top bottom or middle? What nutes are your feeding her. How much of those nutes are u feeding her? Soil/coco/Dwc/FloodTable/etc

to me it looks like it could be a couple things. Make sure your feeding her. dont be afraid to jack the ppms up a bit. a good median range would be 4 to 600ppm make sure you dont have any salt buildup or anything either. it can throw your ph outa range and your plants wont be able to uptake the nutrients they need.
 
this is what i was thinking to...those brown spots could be calcium spots. the way i tell if its calcium is if those brown spots show up on the leaves that are getting direct light. usually the leaves directly under the light will start it first. then it will start to spreads to others.
Would you not have that yellowing though between the veins with magnesium?

I’ve had it before when it first starts the only thing you will see is the brown cal spots. But I’ve had it before to where the yellowing shows up first. Usually youll start to see them at the same time.

We still need a lot more info about the grow to come to a reasonable cause

I was watering it the same amount as two older plants but the younger one vegged longer so was bigger than the other two .. why I think maybe over water.
youll no if your overwatering. plants will look droopy and if you look at your leaves, youll see the green parts between the veins swell up. the leaves will almost appear "fat". water every 2 to 3 days depending on pot size and depending on how big your plant is. The smaller the pot the more frequently youll need to water. big plant in 1g will probably need watered every day.

If your in soil or coco lift up your pot and try to push 1 of your fingers thru 1 of the holes in the bottom. if it feels wet dont water. if its dry water. Youll learn to be able to tell by the weight of your plant they get very light when they need watered.

also if you dont have a ppm meter, that should be 1 of your next buys. wouldnt suggest anyone trys to grow without 1. save alot of frustration and headaches. without knowing, from the pictures you posted it looks like your plant is hungry. id feed it calmag with a nice shot of base and a nice shot of flowering nutes.

Thank you! I have fox farm trio but yet to scoop some cal mag .. what nutes you use?

Don't get hung up on nutes - they don't need a lot, just the right ones at the right time. Your FF trio should be plenty to get you a few plants harvested and some experience under your belt to know what you want to do next. You can waste a LOT of money just starting out on stuff you don't really need.

Use a maximum of about 50% of the recommended doses each time you feed. Maybe start less then add more if they like it. I feed at 25% of the recommended using other FF nutrients.

use calmag everytime I water.
👆 This. Especially under any type of LED, they use more cal-mag. This is probably more important than your nutes for a healthy plant. PPM is an easy one though. Cheap meters work just as well as expensive ones. (not so with pH meters). I don't add cal-mag by ppm though. 5ml (1tsp) per gallon of water every time something wet hits my plants :)

Oh, and don't feed every time you water. That is how I use the PPM. I feed when the run-off shows that they have eaten most of what was there already.

2-3 days is a good timeframe for watering, but it depends on plant size and pot size. Lift the pot before you water. If it is heavy - there is still water.

One of the easiest things you can do to get better at growing is recognizing when they need food or water, and when they don't.

If you have a pic of the plant/pot you have issues with there's a lot people can pick up on besides what you showed with a few plucked leaves.
