Not sure what this is at all.

Can someone help me identify what is going on here. I am currently in Day 14 of flower. I watered approx 2 days ago and I think I overwatered slightly on this plant. My other plant drinks quite a bit more then this one. The plant has been healthy so far. Is this a nutrient def or what?

Check your water PH.
Could also be a magnesium deficiency

Should I check the runoff? Maybe let about 30% run out the bottom and check it? I am afraid I over watered because the leaves were droopy as well.

Check your ph before u water,and also your runoff.
Your runoff will tell u scads of info,and testing b4 hand is a good idea if using tap city water.
If u think u over watered,then wait a bit to dry out some,and add mag to it.

Strange. I always check ph before watering and I also just calibrated my PH pen again recently. PH is always between 6.9 and 6.0. The soil is very dry now so im going to water with Cal-Mag 5ml per gal. Water with 1 gallon. Check the runoff and if the PH is fine then its probably a def.

Thanks for the help!

*edit* Just checked the runoff and its at around 5.8 so something must have went wrong at watering. I watered with PH 6.6 this time so hopefully it should be back to normal.

Good deal.
I'd bet the added cal mag will fix ya right up

Now just to be clear. This will not improve the current leaves, It will only help newly developing leaves correct?

Itll help the current leaves,as they are living and taking in nourishment.
The dark spots will remain,but yes,it will still make the leaves healthy again

Hi Solitary,
the water out being fairly low...could indicate some nutrient salt build-up. Salts like that are always accompanied by various degrees of low ph.
That plus the fairly dark leaf color tells me...would not be a bad idea to lower nutes...say 25% from where you are. Calmag in...good wet dry cycle...you're on your way. You using bloom nutes now? I would.

Yah im currently on the Week 2 Flower Dirty Dozen feeding schedule. Its so strange because so far everything has been great. I did notice alot of water in the bottom of the pan after watering so im pretty sure I overwatered by alot with a very low ph. Completely accidental as I check my PH alot.

Just watered with a touch of Calmag and we shall see.

So far throughout the entire grow the plants have been getting watered every other day like clock work. And that was at a gallon per day. I shouldnt have changed anything when I saw how quickly the other plant was drinking I thought they both needed more water. Guess I was wrong considering the other plant is doing perfect.

I can see that happen quite easily. But any garden that contains seed olants and different strains is facing a challenge. Plant requirements can vary wildly from strain-to-strain and even pheno-to-pheno of same strain. Few small growers mono-crop.

I have some landrace sativas that have been growing since before my last grow. Still in flower at around 14 weeks and hardly need any food.
Three of those that are each different from each other. I keep my res really low...I use that to water light feeders. Then I use a 1 1/2 gal pitcher and add a little concentrate. And again...if I happened to have a heavy feeding afghan.

Looks like a P deficiency to me. Ca is usually rust colored punctate spots and Mg is usually an interveinal chlorosis. Also doesn't look like to much N LOL leave it to me to be different.

Morning Curious,
It's always easier with a well developed deficiency...early ones get into subtleties.

I drew a conclusion based on a mildly acidic rootzone and dark leaves. No...not the super dark almost black that some indicas can get from excess N...but considering that he's in flower now...N reduction would not be a bad idea...that's my thought process.

Not as familiar with P deficiency...but right now I have one plant with red petioles...I better get to reading up.
Cheers,
JD

Figure I would update. After watering with PH around 6.8 this is currently what the leaves look like. They looked like this yesterday but they already look better. Im thinking more of a toxicity and ph problem, probably to much N. Going to water the next 2 times with just PH Water and let some run out the bottom. Seems the leaves have gotten some moisture back in them they are no longer dry to the touch and brittle.
