Brown rust spots on plant to much nutrients?

Any help would be great, this is the last day of veg I have to flip to flower or else I think they'll be to big for tent.. I don't know what to do lol i just saw this today but I think there has been signs, some of the tips of my plants have been turning brown check the pics thanks in advance for the advice I truly appreciate it

What are you growing in, ppm, ph, ect..? Looks like they need a little Cal/Mag.

Im Growing in soil ph is about 6.5 and I give them all about a tsp of cal/mag per gallon of water and I don't have a ppm meter smh

Yep, looks to me like you might wanna back off on the nutes a bit. Flush em out and add less nutes.

With plain water 5x the volume of your pot size.

Just one time? And how fast will they recover?

Evan,

Please.
Take all this slow. I want to list some questions...

1. How are you measuring your soil's ph? Your soil's ph looks quite low to me. Im not interested in your water. Or your waste runoff.
What is the soil's ph?

2. What is your soil amended with? Do you know?
NPK?

3. Ph down, can build up in your soil. This creates acid in the soil. Whether its phosphoric, nitric, sulfuric, or citric.
I stay clear of ph down for soil. Amend your soil, dont bath it in acidic water trying to neutralize it. Id top dress with some lime. (find the true ph value of your soil first).

4. How often does the plant get watered? Ample waste runoff every time?
Aeration /drainage?

5. If the low ph of your soil is amendment related, flushing will fix the problem for bugger all time. 2 days later you'll likely be back to square one.

Plain water. No down.

Give us more information. Starting with soil ph.

Good luck,

Tim.

How about heat damage?

1: I have a ph meter
2: I think you mean what nutrients I'm using General hydroponics flora nova bloom, kool bloom, flora nectar, and calimagic
3: I almost never use ph down (but I just flushed and I used ph with the flush fml I didn't know)
4: I water every 3 or 4 days usually and there isn't much run off

How do I check the soil ph?

They look dark. Too much N. Suggest too much of other elements. Salt build up.

I'd say mix your nutes weaker and water more. You want good run off to prevent salt build up.

For.the time being I don't think you need to flush. Just water only the next two or three waterings with plenty of run off.

Always start nutes at 1/4 strength and work up. I usually don't go above half strength.
