1st time grow auto white widow

Switched over to the general hydro nutrients on April 16. I clean my dwc bucket every 7 days. I'm using clay pebbles for the media. I also rinse those pebbles off when I clean my bucket. She's really packing on the leaves. Even though I'm using 5.5 gallons of ph neutral water in my dwc system I only used enough nutrients for 3 gallons of water. I am sure I had nute burn. Hopefully these new nutrients will work better for me. The smell is getting stronger. I did see some white pistils near the stem. Definitely female and I'm thinking she's in the flowering stage.. That is another auto white widow in the soil growing but that's for another grow diary.
