What Deficiency Can This Be?

My grow box is small, therefore I planted them in small pots, aprox 1 gal. I have a NL and a C99. The way I was watering them was by getting 1 gal of bottled watered and give half a gal to each, I wouldn't stop when I saw runoff, I just poured the whole half gal to each. Upon doing some reading, it seems I was watering them as if I were flushing them. Since I saw some signs of nute, I stop putting nutes in the water, I've been doing this for a little over 2 weeks, and I think my plants are suffering from P deficiency.

What say you!?

looks over feed..what did u feed it? and do u ever flush? those spots in pic#1 indicate built up salts in your medium, pic #2 indicates over fertilization and #3 looks like a heat issue and over fert..so i would FLUSH and check the temp

I feed them Dyna Gro Bloom and Dyna Gro ProTek. I have watered them with ONLY water for the last 2 weeks, thinking it was nute burn or over feeding, but it was getting worse so I started searching and it looked like nute deficiency to me. So, I started using nutes again, 2 waterings ago, but the dark spots and general sick look is starting to spread to the new leaves around the buds.

I'm wating for PetSmart to open to get a PH tester and some PH up/down just to check if my PH is effed up.

Alright, so I got my PH solution tester with a small chart. I tested the bottled water that I'm using and I got a 6.0 reading (maybe less, because the chart goes from 6.0 to 7.6) I also tested my tap water and it measured at 7.6.

Because I ran out of bottled water, I got a gallon of tap water and ph down to 7.0, then watered my NL plant and stopped when I saw run off, checked the run off and came at 6.4 - 6.6.

I didn't test the C99 runoff, cause I had watered/fed her last night, cause she was droopy. I test C99's runoff tonight or tomorrow.

Here's some pics of the C99 out of the grow box. As you can see, she looks sick as hell. I'm thinking of harvesting her right now.

yea it is a PH problem thats why your leaves are sizzled up..ph down your water to like a 4.0 the next couple feedings and check your runoff everytime..water really slowly

PH down?? But the water I normally use came at 6.0 PH scale. Do think my ph is high, even if I have been watering with a low ph water? Shouldn't I be watering it with a 6.8-7.0 ph'd water?

Thanks.

Your ph is way too high (assuming youre using hydro). If you're using hydroponics, you want to be within 5.8 and 6.3. Your nutrients aren't being taken in even though you're feeding (or the nutrients are available) them because your ph is off. Most of your problems will fix themselves once you balance the ph. Make sure to test the runoff water for better results. Once that water is fine, you can feed again, but definitely feed lightly (maybe quarter or half strength) and make sure to ph the solution before applying!

If you're using soil, sorry, never grew soil before but the principles are the same. The PH range will be different for soil than that of Hydro.

ok well DJ dont mean to be rude but look at his pics there obviously in soil.

I cant really see it being a PH issue. as your nutes should have brought up the PH a bit, also you said your run off was at 6.4-6.6 so your good there. I also believe you made the issue worse by "flushing" them with just straight water. As you have now washed out any of the nutes that you wear feeding them with, and as late into flowering as it looks thats not a good idea, this is when they need it the most.
From the way it looks like is that in the start it was a Nitrogen and Potassium(K) deficiency, then when you flushed them it worsened it which is why you got the brown spots and then caused a Phosphorus(P) lock out which caused the leaf curl upward the way they did.

I would advise first do watering with 1/4 strength nutes phed to 5.8 to wash out any salt build ups you will want to see about a atleast a gallon run out. Then water them with your full strength nutes at 6.2ph. Also cut out the dead leaves and any that show about 50-75% damage
also this is just my opinion I am by no means a pro

Just saying because my Coco + Perlite + Vermiculite mix looked exactly the same so I was just giving him advice on it just in case that's what he was working with. If he's using soil then he can disregard my message.

FUCK THAT!!! whoever tells you to water with 4.0 ph'd water when your runoff is at 6.5 and your growing in soil, just don't listen. if your runoff is at 6.5 or 6.6 thats perfect, you don't have ph issues, i'm thinkin you've got bugs or a nutrient problem.

Thank you very much, this is exactly what I was thinking. I got some CaMg+ from GeneralOrganics hopefully I've got all necessary nutes for them to spring back to being healthy plants

lol calm your ass down junior..yea a 4.0 wont change it that much and if he has high salt build up in his medium it will help prevent more burns..and i coulda swore he said his ph was 7.0..anyways junior u better watch how u talk around here we aint all first timers like yourself

yea 4.0 the water if the ph of your soil/medium is to high...just cuz u water with water ph'd at a 4.0 doesnt mean your soil/medium ends up being 4.0...and i said water it twice with 4.0...if his ph is 7.0 then that would probably only take it down to 6.4

my bad man i just thought that sounded like an awfully drastic change in ph... i would never make my nute solution read 4.0 if my runoff reads 6.5. just don't make any sense to me at all mate.
