Leaves don't look right to me first grow ever using DWC help

The leaves look off to me just looking for some advice on what this may be I was doing some research online and it could possibly be root rot since from what I understand is a common problem in DWC. I have great white and have been using it when I switch out the water which I do every seven days. I use a quarter teaspoon for three gallons (I'm using a 5 gallon bucket with two air stones but only fill it up to 3 so I can have a gap of air for the roots) and the brand of nutrients I'm using is Cutting Edge and I keep the water PH at 5.8 - 6.0 . The humidity stays at about 49-50% and the temp is at a regular 73-77 degrees in tent. I have 2 fans providing air flow and a carbon filter I'm also using a 100 watt light 2 feet away from the plant currently and I'm not sure what the issue could be. Please help.

Is great white like hydroguard? That along with the airstone on at all times should protect you from root rot.

Those roots don't look rotten. They get brown and slippery.

You are sure about your temps?

Most people go the sterile rout in dwc when a chiller is not available. Great white is bennkfical bacteria.

Do you use tap water?

Is the bottom of the net basket at least 1/2” above the solution?

I have a thermometer that is on at all times and I check it on a frequent bases so I'm pretty sure about the temps unless my thermometer is off. I was also told if I didn't have a chiller to use great white to avoid root rot. I'm completely new at this so if you have better suggestions please let me know all help is welcomed

I was told to use either or but I'm thinking of going the hydroguard rout to be sure

How often do you check EC, pH and solution level?

every few days

Those crooked leaves are a deficiency that I can't remember. You must be a little light on feed. I don't know anything about that great white crap so that could be throwing things off.

Brown slime algae it’s a Cyanobacteria. U hafta nuke ur entire system. Cap ful of Clorox in ur buckets and a warm peroxide bath in another bucket will help. feed it some recharge too. Or compost tea.
