WTF is wrong with this plant ??

OK, first I dont know if there is a general thread to ask about plant issues. Maybe that is an idea for a sticky or something ?

4 gallon pot, promix/perlite mix. generally feed a Dyna-Gro mix, with Protekt, Grow/Bloom. mostly been leaving out the Bloom lately.
I also add in a little Floralicious + for shits n giggles. not every time tho.

PPM's are between 450-800.
PH- 6.4-6.5

i give it about 3/4 gallon of water/nutes every other day, I try to do just water every other at this point. it seems to suck it right up.

12/12 50 days.
1000w HPS air cooled hood. avg temps 82-85 lights on.


Anyways, these leaves are off a soposed, DP Blueberry. however, it is not a blueberry pheno, it jus happens to yield well, and does the job very well.
I figure shes got bout 2 weeks left give or take, I use a scope for trichs, never rely on breeders time frames.

Now to the pics.....




My camera sucks, and its hard to get decent pics with it....
its really hard to see how much yellow is actually on the plant, but I pull leaves off like this everyday...





Im considering a soil flush soon as the soil drys out and is ready.

Spider mites have been a issue, but not out of control, sprayed with mighty was the other day.

I may wait for lights out and get a couple other pics, hopefully itl show the condition better.


Anyways, im open to suggestions, its the only plant in flower showing these signs.

your over feeding your plants bro nute burn are u relly feeding every watering?

flush them pots i bet there is a shit ton of salt build up .... deff nute burn though i only feed my ladys when they look hungry or 1 time a month if they dont show signes of needing food

Well, more like every other watering really. I figured im running low PPM so it wouldnt be that bad of a thing. Ill back off n see what happens.

I figured where its a promix medium it dosnt provide any nutes, any idea how long I should go in between feedings? like i said this thing needs water probly 4 or 5 times a week.
I usually try n flush every 3-5 weeks. its about time anyways.

at the most every 2 weeks i would just wait untill they are hungry and when you do feed make shure to only give 1/2 reccomeded dosage

Well put her in the shower and flushed the pot out pretty good i think. ill be paying attention to it closely the next couple of days.

I have this same problem all the time. usually its only one plant, but ill back off the feedings. hopefully thats my problem.

check your ph of your runoff, i can bet my last dollar its in the 5.0 range or lower. promix mix is very acidic, something i found out the hard way.

OK, Lights are finally off...
I hear ya bout the promix being acidic. I sprinkled a little lime on top and watered that in yesterday, but now its had a decent flush, so ill have to check the run off in a day or two when it drys out a little.

camera still sucks, but this is what i got.



I think promix is kinda a pain in the ass to use, but its plentiful & cheap.
seriously think im gonna try coco coir next... maybe a perlite/vermiculite hempy bottles or something.
im really jus trying to find the easiest, most consistent medium to use.



What is the proper way to check run off? how much of a sample should I collect? should it be the first water out of the bottom, or the last drips?
should I jus take a sample of the soil and mix it with water till its a slushy?

Just never can seem to find a straight description as to what is the most accurate way to test soil ph.


And if it is determined to be acidic, is a top dressing of lime watered in good enough to fix it? how much lime?

leaves are supposed to yellow at the end of flower showing it has a n def. n in flowering isnt good it makes for airy buds im gusseing it was just lock out from the salts though that lime should help..

i take 15g of soil and mix with 15g of ph 7 water stir wait 30 min strain with a coffee filter then check the ph

make shure you check the ph of your water before you water your plants also because all of thoughs nutes you have been giveing has most likely droped the ph i bet the flush will help allot.. when you flush make shure to flush 2x the volume of you container for example if you have a 5 gal bucket flush with 10 gal of water .
hope this helps man
much love

Those bitches look about 2-4 weeks from chop-chop city, you should have some yellowing of fans leaves at this point, although not to the degree you have yellowing.

I'd personally give them a hearty flush ( i.e. 16-20 gallons ) and maybe give them a 1/2 dose of nutes the NEXT time you water. You're almost done and it's a bit late to be concerning yourself with fixing this nute problem.

Next grow, ease up on the nutes and stop watering so much.

Just my opinion.

Yes, I always PH my water after nutes are added in. 6.4-6.5 usually what i shoot for. Tho usually Dyna-gro puts me right in that range anyways.
Ill deff do a soil test for shits n giggles tho.

Yes, I figure about 2 weeks, might go an extra week tho. the buds are very hard & dense .

I understand its a tad late to really SAVE this one, tho I still expect a decent yield from her. Like I said I seem to have this problem on at least one plant every time.
She got a decent flush, so now im jus waitn on the soil to dry out. And go from there I guess...


How much water is 15g ??

you dont have to weigh it thats just how i do it. you could do 1/4 cup of soil and 1/4 cup of water it will still tell you ur ph

sweet, thanx bro, thats one thing that has always confused me. I just figured there was a measurement equivalent to weight when dealing with liquids.

yeah it sounds like from the constant feeding, you over indulge on a nutrient that it wasn't taking in causing salt build up which also caused the ph to drop and not take in any nitro.
yeah promix is a trip all in itself. i thought i was the only one with these type of issues until i posted and googled promix, welcome to the club.

Right. Iv been using promix for years. even using it in my guerrilla grows iv had issues with it. Seriously considering going coco next time.

Any idea how much lime to a 5g bucket would be a good starting point to amend promix? what if i jus use it for a top dressing ?
