First time AUTO-flower - White LSD Auto

I began fertilizing this week. I began with a General Feeding of half-strength every other watering. I added the Sensi Cal Mag in the first feeding just so it is in the soil if needed. I was also advised that a good practice in all watering's is to drop one US quarter & one US dime in the gallon jugs. Apparently, small trace amounts of Copper, Magnesium leech out in to the water & provides added protection from lack of these trace minerals. I also topped her for the first time. I have no idea if it will work but, I took the Top & dipped it in TakeRoot to see if it would produce a clone. If it doesn't work, no loss. Better than letting my dog eat it !
