Hello guys

Would you tell me your thoughts about this baby clone?
pH 6.2 stable
eC: 0.8 stable (starting with 130 ppm water)
nutrients: Generic brand that used to work in the past very well, i live in south america so no access to fancy brands
water temp: 18 C
ambient temp: 25 C
CO2: 1300 ppm

Yes, what you see in the pot are river rocks, works wonders

Hi,
I reduced ppms to 250 on tuesday as you told me.

Plant doesnt appear to be improving but roots are growing at great rate

Today I measured PPMs at 230, meaning is eating.

Would you think is good idea to increase a bit PPMs to +/- 300?

Yes, that plant is starving to death. Your water level was low as it looks like they are (the roots) just finding water recently.

You need to treat it as a coir grown plant before they have roots established. Watering through the netpot daily. That plant doesn't know what to do, roots follow flowing water.

Hope you did your homework and haven't planted clones with rockwool in DWC?

Hi guys, plant has improved a lot, yesterday did a water change and increased PPM(500) to 330 since i start observing some deficiency (See red circles)

I added some perlite and start topping off as Wastei suggested

I observed some slimy root rot where roots are in permanent contact with water, i'm adding 3 ppm chlorine (bleach) every 3 days more or less, water is at 18 celcius, any suggestion? maybe too little air? maybe need more chlorine?
It seems that is preventing roots to grow even further.

Hi guys, here again

Ph was 5.6, ppm at +/- 300.
I really dont know if it is nutrient burn or deficiency, thoughts?

How the hell can they be locked out with 330 ppm? I really dont get it

1st comes the burn, then the lockout. as soon as you see tip burn, you gotta drop your EC rather quickly.

now you need a 24 hr flush with 0 ppm water. then start back on lighter nutes. like 150 ppm. as they can handle it, raise it up slowly

well something’s different this run. What did you change?
You haven’t provided info on the nutes yet? The res temps are 18c and the room is 25c, right? You’re injecting air into the solution, how are you cooling it?
Tell us about the lights.

Nutes are no known for you as I live in south america and it is a local brand.
Water fluctuates between 18 and 22c.
Cooling with chiller
