Hi there! Yes if the netpots are not in the water it would be good to keep it all moist just in case until the roots hit the water. I try to put the whole netpot with the rockwool in the system so that the rockwool is touching the water all the time. This might have some problems from what Ive read but im not sure if I have run in any.

It's not a deficiency it's an excess. any strain any cannabis plant when feeding hydroponics.. Start with no nutrients for approx 4-5 days then once the second true leaves emerge you add the nutrients.. In your case of the flora trio I would use 2.5 ml grow 2.5 ml micro and 1 ml of bloom to 8 liters of water. This is how I grow hydro.. I grow trees :).

You have a good air stone rocking the water in there? Is your water cool, frozen bottles of water can help keep it cool. Your ec should be about 1.0 until you see they need more. Maximum dissolved oxygen that water can hold is between 62 to 68 degrees. Your plants need this for vigorous growth and root health. Can grow in higher temps but not as good, plus you have to add root guard which you dont need if you keep the water cool. Luck my friend Cheers

Hello. Hydrogen Peroxide doesn't like bacterial or fungal growths, so it will help there. Algae: do you have light on your water? HP won't help with algae. My starting point for mixing is 1 ounce of 35% HP to 5 gallons. Increase if you need to. Good Luck. Chuck.
