I had to go out of town for about a week, so was not able to flush the system until today. It looked like some of the girls were suffering from either nute overdose or Mg deficiency. I flushed 1 oz/gal of Clearex thru each of the plants, and replaced the reservoir with 1.5 tsp/gal of the grow, 1/2 tsp/gal body builder, 25 drops superthrive, 1 tsp/gal Liquid Karma, and 1 tsp/gal CalMag+. I also added an aquarium heater to keep the water at 72°F (it was about 65° before), and a bubbler to keep the water mixed up and oxygenated. They seem to be improving well with the new growth coming out.

The first 2 pics show the Mute on day 30. I tried to get a close up so you could see how strange she is growing. Right past the cotyledons (which are still present and green), a new much larger stalk started growing out of the side. Strongest plant in the garden and I am praying she is the right sex. Can anyone tell any early signs of sex based on these pics?

The next pic is the Sagarmatha who was showing signs of nute problems, yellow and crusty tips. The 4th and 5th pic are of one of the Satori's and the worst Sativa Diva at day 17. They look much better today after the flush.
