Temperature: 25°C (Lights on)
RH: around 50-55%
High Quality Coco ready to use (Ec 0.1)
PPM feeding: 600ppm (1.2ec) 6.0 ph with
remo nutrients for veg according to the table.
Runoff - Around 350ppm and PH of 7.2 (i got that ph recently but when it was around 6.2, the plant was having the same problems...
I tried to run 800ppm and 350 ppm as well, 5% of pot volume and 10-20% runoff rule.
I flushed them already, 2 times, one with light nute mix and one with 5.8 ph water...
It has a fungus gnat infestation and im running h202 3% (1-4) right now (for the first time yesterday) and ordered gnat traps, and trying foliar
neem oil... what do u think that is?
I didn't read anyone elses reply, as I know exactly what it is.
First off, your environment is super healthy in the root zone, that's why your run off is so much higher (ph) than what you're feeding
Also, if you're runoff is 300 ppms less than what's going in, your plants are eating.
PH HAS to be correct, or your plant will not intake essential nutrients!
So if you have 6.0 8n, and 7.2 going out, your root zone is WAY hight. It's always good to see your ph coming out higher for several reasons.
Anyway, this is about a 4-7 day fix.
Flush with your nutrient solution at 1.0 EC (500 PPMS) until you're runoff is WITHIN RANGE.
Ideally, you should have 5.8 going in, and 6.2 coming out..flush at 5.6-5.8 tops.
What kind, and size lights you use dictates how much you can feed.
Ex. A 1k HPS plant can take a much heavier feeding, than a 150 watt. It's not so much the light that makes them grow so much bigger, and faster with a 1k hps, but rather it can use more food.
Anyway, i know I'm new here here again, but I've been doing this over 30 years. Hydro for 20+. I've seen it all, and I don't hsve grows that fail (I could have equipment fail) but I get the absolute potential of a plant.
Anyway, SHORT ANSWER, YOU HAVE PH LOCKOUT. GET IT IN RANGE.
I wrote all that for anyone having issues. Always check PH 1st
You'll have her happy, and healthy in no time..Depending on the power of your light, you can flush with a bit higher EC
