Alright, here we go. I'm probably doing many things wrong but thats why I'm here. I got an indoor soilless system going for about 4-5 weeks. They were clones to start off with and not in very good condition. I believe they are granddaddy purp.


Grow Medium: Hydroton in plastic bag pots.

ph: pH for the res is between 6 and 7. I guess about 6.7 (hard to tell with pH paper) goes down when the water is on.

Light - 400 watt MH (18/6 schedule) about 20 inches from plants

Plant Height: Tallest (left back corner) 9.5 inches Shortest (right back corner) 6 inches

Roots: Roots seem healthy, there a bunch coming out at the bottom of the bags.

Water: Tap water after it has sat at least 2 days

Temperature: 80 light on/75 light off

Watering: Every 3 hours for 15 mins when the lights are on. 6 hours no watering when the lights are off. The tray fills and drains. I add water to the main res from a backup res almost daily to keep up water levels.

Ventilation: Using a regular fan for ventilation. Closet has doors usually open and also has an open attic (screened)

Nutrient:
Supernatural Gro Terra 20 20 20 mix
Total (N): 20%
13.95% Ammoniacal Nitrogen
6.05% Nitrate Nitrogen
Available Phosphate: 20%
Soluble Potash: 20%
Boron: 0.02%
Copper (chelated copper) 0.05%
Iron (chelated iron) .1%
Manganese (chelated Mn) .05%
Molybdenum .0005%
Zinc (chelated Zinc) .05%

It looked like I got some Nut burn so I don't use as much.

The res is about 10 Gals. I use a tablespoon of Gro Terra every other day (real tbsp not a measuring one) . Changed the water twice since I've started.

There is a spider-mite problem I have been battling. We have a dog, she doesn't go in the closet but sleeps in the room. It has gotten a little better. I use Spectracide's Triazicide sometimes but I mostly manually remove them.

So now tell me what to improve I don't have very much money to spend but if I really need something I will get it.
I was looking into Liquid light by Dutch Masters, sounds pretty cool but tell me what you guys think. Also I am concerned about the low water level in the tray. I think it might be too late to fix tho And there is some standing water at the bottom of the tray but not much and tends to evaporate.

How much longer should I wait before flowing. I got about 5.5 feet of room above the tray. (not including the light fixture)
