Is this a P deficiency?

[Goodshit97]

Ive had this plant growing for a while now, we havent been able to get along for some time now. Im now running into some nasty looking leaves and was looking for some input on what it is/how to fix it.

Running fox farm ocean forest soil, fox farm trio for nutes, pH is 6.5-6.7, runoff ph is 5.9. Water water feed is my schedule. Every time im not feeding i add calmag. 5ml per gallon. Mars hydro tsw 2000 is 26 inches at 70% temp is 75, rh is 55.

Is that cal-mag with every time you water? (Minus the feeding)

Pretty sure it’s calcium toxicity, (too much calcium) which can also inhibit other nutrient uptakes, causing more issues.
I don’t say this often, but I’d give her a flush to get the calcium levels down (if that’s what it is, not 100% sure, just going off what’s posted) I’ll include a little reference photo below, hope this helps a bit

I've never heard anyone suggest calcium toxicity. Interesting.

Is it only on the lower part of the plant right now?
Why do you think you need "calmag"?
I'd raise the temp if you can do so easily.

I like to add a little citric acid to the water for flushing out excess Ca. It's supposed to help.

Put the CalMag on the back burner often people use cal mag as a nutrient which at low levels will work. But you shouldn’t be feeding it at 5ml every time you water. Good luck! Flush at 6.3ph for a couple waters it should perk up.

Hey, weren't we kinda discussing citric acid and other options for "de scaling" (essentially) or removing salt buildup from pots/equip before? I remember asking what people thought about various products or methods.
Update: Citric acid worked the best. It took a bit longer than I thought. But the salt buildup *disappeared*. Ie: I didn't even have to scrub.
Sorry I don't have a rate for mixing though.

Do you know how much would be ok to use to try out what you're suggesting?

I guess citric acid is used as a pH down sometimes, no?

Nice. Ya, that was probably me.

Forgot to add just flushed this plant for the last 4 days at 6.2 and its only getting worse.

Is it only on the lower part of the plant right now?

For the most part its the lower part of the plant, and i just flushed her for the last 4 days thats why i was thinking deficiency not excess. Its only gotten worse. Just feeding calmag bwcause i thought it was needed. I dont really know this is only my third grow and the first 2 were autos these are photos. Temp can definitely be raised ill adjust my ac

I didn't look at the pics until just now. I'm not a fan of FF nutes. How much have you been using?

15ml of big bloom and 15ml of grow big per gallon is all ive been feeding. No more no less.

Its all i can really afford for now. And i dont have any other advise for decent nutes

How have you been adjusting your pH? Are you adjusting the water only feedings too?

 

[Goodshit97]

I use general hydroponics Ph down, ph at the tap is 7.2-7.6. Some chlorine added as i live in a trailer park and it has to be treated.

I only have to adjust the water only feeds as the ff nutes are ph buffered.

That could be the problem right there. Too much of that stuff will lower soil pH. Stop using the pH down. 7.6 is fine in soil. My water is more like 7.8. I'm guessing your soil is kinda acidic now maybe.

I'd give it a dose of the FF nutes, then plain water and try to tell if they look any better either way. If you don't notice a difference, then on the watering after those 2, I'd add some water that's been pH'd to like 9 and see how they respond.

 

[Goodshit97]

Right on. Ill do just that seeings how they just got fed tonight. I noticed when i check my runoff its 5.6-5.9 never above 6. Also my ppm was like 2700 so i ran 3 or 4 gallons right out of the tap and brought it down to like 750-800.

Don't worry about the ppm in the runoff. Runoff pH isn't a great way to check pH, but I think it can give you an idea sometimes, but it can also be misleading.

And only flush if you need to because it's just leaching the nutrients out of the soil.

But like I said, if you get to the 3rd suggestion and water at 9 or so, you could check the runoff pH just to see.

Sounds good. Thanks for the info. Will update in a week or so.

I only flushed the plant cause it has been in a 5 gallon pot since february and she was getting pretty salty.

I think your using to much maybe?

Sorry never mind wrong nutrients, thought you was using GH.

So about 10 days hqve gone by and its still the same yellow, brown crispy leaves. I dont know. Deficiencies and what not all look the same to me lol.
