Hey guys, first time Dwc grower. Running 8 5g buckets under my 2 ts3000 lights. Lights are at 90% at just over 24" height. Growing In a 8x8 tent, temps are 75 in the day, 67 at night. Humidity pretty locked in at 50-60.

On Friday I did a water change moving into week 4 veg of future harvest hydro line, minus 10% strength.

Using micro, grow, bloom, propogater, Suber b and calnesium.

This was the first time i mixed up the whole batch in my res (just running Dwc not rdwc). So mixed up a 25g batch of nutes, PhD to 6, ppm was at 1080. Filled up buckets.

The 2 Alaskan purples I have growing are both showing this same kind of discoloration on a few of their fan leaves. The other strains (2 x Bruce Banner and 4x cherry pie) look ok. Just the 2 ap's are showing these issues.

I'd that a calmag deficiency for these guys? Previously I had mixed the nutes up for each bucket at a time (just nervous to make a big batch lol) but they had always been mixed at the same rate as the other plants.

Propagator, dont use that shit.It doesnt mix with other nutes well.
Why just dwc seams like a lot of extra work,anyway ya stop the propagator junk.I used it years ago with nutes nothing but problems.

Fairly dark green, maybe too high ec. Feed charts can usually be halved. They make those recommendations with optimal grow rooms in mind and zero problems. Your plant prob isn't week 4 as far as the nutrient requirements go.
Those charts by the week kind of hurt new people more than they help.

My 1st grow was a dwc nightmare, use hydroguard or something like it. Root rot is something better to read about than to experience.
