plant I have in soil
 

Yo, Ron; This is an update on the 2 month old (now 3 months old) plant I have in soil, and using Formula One. I have reset my light for 12 and 12, and adjusted my nutrient to 1500, at 6.5 pH. I have been feeding the plant 3 times daily until the solution begins to drain from the bottom of the pot, but that was on 24 on. Now that the light period is shorter, should I feed as much? By the way, this plant is sucking about 1/2 gallon per feeding before the solution comes out the bottom, and is VERY healthy. Been on new photoperiod for one day now. Want to try to get it worked out for automated feeding before going back to work after holiday...Happy 4th!

(Response) You shouldn't water at dark period with dirt.

Ron... I know ya don't water during dark period...My question is "Should I be feeding with Fomula One at 1500 ppm EVERY time this plant gets watered? Plant was wilting very badly after 3rd day at 12 and 12, with 2 daily feeds @ 1500 ppm, and 6.5 pH. Leached pot with tap water (4 gallons) at 6.3 pH, and gave full outside sunlight. Recovered within 2 hours. Am I overfeeding???"

According to the direction on the bottle you mix 1/4 teaspoon of A and 1/4 teaspoon of B to a gallon of water every time you water your plants.
That is 1/4 the amount used for hydro so I think you are over feeding it.
