HedgeHunter.... Frequent feedings / waterings will work against you in soil growing. If the plants in your Avatar are your current crop - repot them to larger pots as soon as possible. Now, back to the weakly / weekly thing :
.
If you feed Mary frequently, she will not spread out her roots very far - since food and water are being dropped in, every few days. Smaller rootball, smaller plant, smaller yield.
.
Instead, water her one week (once - a nice heavy soaking), then leave her alone. The next week, feed her a regular strength (dose) of nutes mixed in the same volume of water. If you have a gallon of soil in your pot, give her a quart of your fertilizer mixed up. If you have 3 gallons of soil, give her two quarts. Then leave her alone.
.
The next watering, don't water from the top - instead set your pots in a pan deep enough to hold one inch of water. Let them sit for 15 mintues, then remove them. That way your soil will draw in the water it needs from the bottom. This helps roots to grow downward.
.
At the next feeding, pour your fertilizer mix around the outside edge of the pot from the top. This ensures Mary reaches outward for her food. Now, doing this will slow growth just slightly in the begining - but the payoff comes later. The larger rootball you will develop will equal larger buds later. So, in my book - it's completely worth it.
.
So, water one week and fertilize the next in rotation.
.
Hope this helps..
