Prevention is key. Once the colonies are formed they make a bio film that are resistant to chlorine and it needs to be raised to an amount that it toxic to plants to do the job according to https://manicbotanix.com/disinfection-in-hydroponics-root-disease-prevention/

I'm using an ORP sensor to monitor how much calcium hypoclorite should I add to the reservoir. Using tap water my ORP was 500 mV and dropped to 300 mV in just one day. I think it was the effect of the bubbles helping the chlorine evaporate. So I used calcium hypoclorite 65% 0.0133g/gal (150 ml...

IR thermometer on leaves 72F. I reduced the light to 8.000 lux.

Sure

The water level is below the netpot. The bubbles made by the airpump let the roots and the bottom of the cloning collar wet. The roots are in touch with the reservoir.

I germinated the seed in the cloning collar. No rockwool cube. No plugs. Nothing. It works. (Or dosent). I do not know if the plant problem is related to the lack of medium.

Thanks for all replies. I think I will lower the light, see how it goes. Change the water to tap ph'ed if no improvements. Maybe it's just better to start over.

Outside the tent is 60f. It is cold here.

I'm not using clay pebbles, only a cloning collar.

Ph 5.8 calibrated pen. 3.2 ft from lamp. I use a luxmeter 15.000 lux.

In a tent. I could raise the humidity with a humidfier up to 80% if needed.

300 ppm=0.6ec 360 ppm =0.72ec There is a fan blowing her

Also res temp 66f, room temp 70f rh 60% 15.000 lux light (3000k quantum board)

4 week plant. Plant was becoming yellow on the 3rd week so I raised the ppm to 360 and the leaves tips burned, so I lowered to 320ppm. Using Reverse osmosis water with 1 ml/gallon Armor Si, 2ml/gal calmag, 1ml/gal micro 1ml/gal gro 1ml/gal bloom Ph adjusted to 5.5 let it raise to 6.2 and lower...
