Hello My friend I'm a dwc grower so let me have a little look into your situation here :) So your EC does seem a little high for this stage check out my Black sugar she is near enough the same age and My ec is set to 0.5 (disregarding the tap water ec) I have no problems but yes I would say its a tad bit too much for her at this stage lucky for you dwc is the best system in my opinion cause you can bin that water straight away and create a new one which should clear this up in about 2 days I would advise popping the ec down abit and then if it doesent clear up just use ph balanced water to feed until back to healthy though nutrient burn will often occur from the leaf edges and inwards so if you notice the sides of the edges getting brown too then thats defenatly an over feed. then jsut flush and you will be fine :) Hope this helps bro

If I had to guess, something is causing phosphorus issues (coz of the yellowing along with the vein gradient towards purple closer to the stem).
So, I can't actually recommend a nutrient balance or anything since I don't grow DWC, but I'd probably give it some calcium and phosphorus (maybe a bit of epsom salts) and/or lower things that could interfere or lock out some of those elements.

My hydroponic feed schedule is
Seedlings take 400 ppm 0.8 ec from the get go. If you see good growth then every week I increase my ppm up by 100ppm.
2nd week 500 ppm 1.0 ec
3rd week 600 ppm 1.2 e
4th week 700 ppm 1.4 ec
5th week 800 ppm 1.6 ec, I stop increasing here until ready to switch to flower nutes.
When I switch to flower nutes I lower the ppm to 600ppm, 1.2ec to start early flower, and after first week, they go to 700 ppm 1.4 ec and mid flower to 800 ppm again. Ph I keep at 5.6 to 5.8 for vegging and 6.2 to 6.3 for flowering.
Hope this helps. Cheers

Yellow leavesHi guys, unfortunately because of an emergency I had to leave my 2 babys with some friends for three weeks. At the bottom some yellow leaves and like burning signs. I don't think it's because of over nutrition. They didn't get any for three weeks. Might be not enough nutrient?

Yellowing and light green leavesHello growers!
My AK has been getting some yellow leaves, big fan leaves and small new leaves at the bottom, and looks less dark green. Is this a deficiency (looks like nitrogen but I don't want to give it even more nutrients) or is it just self defoliating? Any ideas?

Is this yellowing normal? Probably because of LST?I am growing my plant with LST and some of the lower fan leaves have been moved down in the shadow.
Is this the reason why those leaves are getting yellow and dry?
All the rest of the leaves look very green and healthy by the way.

Lockout or deficiency?I have an issue with a girl.
Newbie alert.
I feel it’s either calcium def or nut lockout.
I fed with 1/2 rec BAC grow feed and it didn’t get better, so 2 days after I gave a flush of fresh water.
Now it’s really trying to grow, it’s kicking out new leaves but it’s stunted
