Is this a phosphorus deficiency

Definitely not time to feed yet then. >2,000 is common for FF OF. It will take a couple of weeks for the plant to consume nutes such that PPM is ~1,000.

pH will remain stable until you start feeding if you are using distilled.

why am i getting a deficiency? im still new, this is my 3rd grow and the first 2 grows i just barely made it through lol

You don’t have a deficiency with PPM where it is when in a quality soil. Something else is going on. Could be an overly sensitive plant showing anomalies due to high PPM or something unique about the phenotype you are growing.

It’s not uncommon for cannabis to show a few blemishes as it matures. I wouldn’t worry about it so long as you have healthy new growth and the issue isn’t spreading.

the issue was only 2 tiny spots that didnt spread until yesterday, heres how it got to looking overnight

That picture looks like nitrogen excess (dark leaves and burned tips.) Is this an auto? Autos are more sensitive to nutes than photos. Autos can be twitchy. I would suspect an excess rather than a deficiency.

26

yea im doing autos, i ordered a bunch so trying to use them up then make the switch to photos, why would they show the signs now instead of when it was younger? its been in the same pot since germ

i have a pineapple express going as well but she looks a bit better-shes just finicky and different/ she likes going to sleep a few hours before the purple punch, my lights shut off at 4pm but the pineapple gets droopy around noon, the purple doesn’t droop until about 1hr before lights out

28

runoff ph on the pineapple was same as the purple but ppm was a bit lower- 1638

Drooping is common around lights on/off and around watering time.

You’ll notice that the blemishes are appearing on older growth and new growth is so far unaffected.

If it were my plant I would let it go. The blemishes won’t heal, but you should get less of it as the plant consumes the excess.

I see some folks have recommended feeding. Feeding would be a mistake with PPM so high.
