Some bro stuff going on now

You should mix your mix then ph LAST watered down if you want to be nit picky.

With your plants i would cut the feed to half strength ph @6 whatever and flush your dirt till the runoff matches what your putting in

Then let it be for 3 days :)
Hope it helps

I have to disagree dude.
Have a look at a ph chart for reference.
If your ph is out of wack at either end you're gonna lock up.
Theres no way around it. If you dont adjust your ph, your plants just cant absorb what they need. Calcium and magnesium being the first.
If ive got the right amount of nutrient it dwc. But the res is out im gonna get lockout. Simple as that. Nutrients are always last.
Overfeeding is the most common growers error. IMHO

I have 3 plants about 31 days into flower and have noticed what looks like is a N deficiency going on from the bottom up. The leaves start to yellow and once they are yellow, they brown, curl and fall off.

The reason I don’t believe it is a N deficiency is I have been making sure my plants are getting plenty of N in their feedings still. I’m thinking it might be a lockout, because it seems to be getting worse after I just feed them. I clipped a couple leaves last night so I can look at them for sure tonight that they are getting worse.

I know it’s hard to tell without pics but I have a couple from my last feeding and the tops of the plants are still looking healthy, but the sickness is defineatly starting to progress upwards.

A little more info about my setup
600W HPS
2 Purple Urkles 1 Pure Kush
Ocean Forest Soil
Temps range from 75-70 at lights on 68-61 lights off
Humidity stays between 30-40%
Been following GH Flora feeding schedule with
Flora 3 part and GH floralicious plus with liquid koolbloom and calimagic

Pure Kush

Will get more pics later tonight at lights on of leaves on the plant
Nice grow man, straight away can tell it’s soil grown by the slight hang of the fan leaves due to less O2 in the root zone. Don’t change anything this is natural senescence of very low leaves due to slightly lowered O2. This doesn’t happen in coco hydro with the rest of the plant looking as healthy as yours do.
I’d say you’ve pretty much nailed it considering you are working with a proprietary soil. Great thread btw

have to disagree zed... not abought the thread lol. plant leaves arnt less erect because they are in soil. my shit is always praying. Leaf erectness is caused by turgor pressure. Turgor pressure is the outward pressure that occurs in a plant cell when the cytoplasm and vacuoles fill up with water via osmosis and the cell membrane pushes against the cell wall. Water wants to travel from places of low salinity to high and is a sign something with your plant is not right. for me if I start to get a bit of a droop I'm due for a flush because the soil is becoming more salty than the plant and the flush has always fixed it. overnight they start praying to the sun gods lol. It can also be a first indication something is wrong with the roots. pests, rot, ect.

YOU talking about me?
 
Some sad news and a little update. Lost one of my purple urkles tonight due to a hermie. I also have some pics of the other 2 and just want some opinions on if what's going on with the leafs still or if it is natural.

Pure Kush not to bad on this one right now only on the bottom leaves mostly

Hey mate. Sorry about the nanners
Just check your media ph and Ec/ppm. If your plants are on the mend, and those readings check out. Id say not to worry. You'd have some irreparable damage as well.
Just check your ph
Check your ppms
Go from there.

I always like a bit of a flush a few weeks into bloom anyways.

You'll be able to give it a proper flush before you pull too, with your ppm metre:hump:
Happy harvest.

Yeah, it sucks with the hermies cause man where the buds on that plant starting to look nice man, but it was learning experience, so it wasn't a complete loss.

Yeah, I was thinking test everything then flush, because I haven't flushed throughout the entire grow, and figured there might be some built up salt, because it's all around the side of the pot on the purple urkle.

PLANTS look just FINE!

The yellowing of the lowest stem leaves is quite normal at this point...

Ignore the calls of too much N...It's not....Don't add more though!

Keep going as you are!

LOOK GREAT really!

I can't agree more. Too many people chiming in with advice to fix healthy plants. As soon as you start deviating from your existing regime and adding extra stuff, don't be surprised if the plants DO actually start looking bad.
