Have a few 4 week old plants using an aero system.

Have only been using full strength nutes for a week, and some of my leaves are curling.

When mixing I mix it in a litre jug, the water ph is at 7 (normal) then put in dutchmaster A & B, then add rhizotonic for root strength and cal-mag. Then put into tank with required water amount and then I adjust ph.

Also is this the correct way to mix nutes?

Running ph at 6 to 6.5 as always.

Anyone suggestions would be great. Thanks people.
