overwatered..Lights: HLG 550v2
Soil: Promix hp.
Nutrients: Mills
A few weeks ago my leaves started dying off, I thought it was a pH imbalance or nutrient lockout. I flushed my plants at 6.0 pH.
Things got way worse.
I then thought it might be a macronutrient deficiency, so I fed heavy, things seemed to be getting better, than again took a turn for the worse.
I am now day 15 in flower and my leaves are all dying.
My runoff pH last watering was 6.0
My runoff ppm was 1300
My room is about 82°F during the day,
And about 72° F at night.
I keep the c02 at around 1300 ppm during the day.
This has never happened to me and this is my fifth cycle. I am loosing my plants and can't seem to figure out why. Very frusterating.
I would love some feedback or ideas from those more knowledgeable and experienced than myself.
Thank you.
ProMix is an organic soil. You are feeding it non-organics. That kinda defeats the purpose of getting quality soil in the first place.Thanks for the input guys, I could definitely see the guy on the highway analogy, I believe they were starved then fed, then I don't know what's happening now. Another thing I thought of was possible heat stress? I backed my lights off a bit just in case.
Also one doesnt need to pH with Promix hp?? I've never heard this before. I know it has the d.lime to balance but I though we still had to pH water/feed?
I will try what was recommended with a flush and then starting back with a slow feed. Thank you
Promix is peat moss. Not organic soil but it is prebiffered so no need to PH usually. Mills is not an organic nutrient. So imo flush is absolutely needed hereProMix is an organic soil. You are feeding it non-organics. That kinda defeats the purpose of getting quality soil in the first place.
A correctly balanced organic system adjusts it's own pH. we just check it weekly to head of any problems.
And organics never flush. but we might soak.
Gotcha. I have'nt used it, but that's what I had heard about it. My mistake.Promix is peat moss. Not organic soil but it is prebiffered so no need to PH usually.
What do you use to "recharge" ocean forest blend ? I would like to try an organic run soon. I've read the nutrients present in OF only last 3 weeks. You use general organics and just feed according to chart?Gotcha. I have'nt used it, but that's what I had heard about it. My mistake.
We use FF OF because all it needs is some recharge and it's off the organic races!
Not 100% but pretty sure the recharge comfortably numb was talking about is this:What do you use to "recharge" ocean forest blend ? I would like to try an organic run soon. I've read the nutrients present in OF only last 3 weeks. You use general organics and just feed according to chart?
Also I'll update this thread when I solve the problem for anyone else who experiences this in the future. Going to water heavy today, and two days from now I'll give a light feed.
Yep, that is the one.Not 100% but pretty sure the recharge comfortably numb was talking about is this:

We never 'feed' our plants anything that is not already in the soil.You use general organics and just feed according to chart?
Imo meter is accurate. Ph in soil changes and you want to go by the numbers in the saturation zone where the most water is. Ph is a measure of h+ ions in water and only dissolved elements will affect it.Yep, that is the one.
You have a serious pH problem and your meter is no where near accurate enough to tell you that.
RAISE light 6 inches or DIM it by 25%.
How big is each pot? If it is 5 gallons, then flush 15 gallons of clean water through each one.
DO NOT FEED
Remove all damaged leaves and then lets have some pix please.
I have that same meter and the ph part is worthless.Okay guys what do you make of this:
Since initial post and feedback
I backed my lights off about 3 more inches (currently sitting 22 inches from canopy)
Then I flushed my pots with water and dripclean, and finished with a light dose of week 3 nutrients.
My final runoff came out to 5.8-6.0 pH at around 1000 ppm.
When I use a soil pH meter the top of my soil is reading close to 7.5, and when I push the meter all the way to the bottom it reads 6.0 (check included pictures. First picture probe is 3 inches deep, second picture probe is near the bottom of the pot) so my soil is completely different pH depending on the depth of the probe.
Now after doing all this my plants look even worse. It's crazy the leaves are browning and falling off like a tree in fall time. This is my first time having a serious issue with a cycle that I can not seem to solve after many weeks. From my knowledge I've done nothing different from my previous runs. Feeling stumped here
