I have two plants that are about 3 feet tall and are grown with Fox Farm Ocean Soil in a 3-gallon air pot, and I use the Fox Farm Nutes (Grow Big, Big Bloom and Tigerbloom) and about 1tsp of cal-mag every other watering. I started using full strength recently based on the Fox Farm Feeding schedule for soil and my leaves started getting a little dark green, so I cut only the tigerbloom to half strength. 1/2 strength of fox farm feeding schedule seemed to give my plants some nute problems, such as a bit of yellowing on newer leaves. I use R/O water (~80ppm, 6.6ph) untouched. My plants are in week 4 of flowering and they have nice buds forming on them.
I feed them every other watering. I've noticed the soil PH on the run-off seems pretty consistent, however my PPM changes dramatically from one day to the other. Here is my feeding schedules from the past few days:
When I mix the nutes, I mix it in a 1 gallon jug and I give the plant about half a gallon of the mixture, until I notice a run-off (which usually fills about a half of a solo cup). Each water/feeding is roughly half a gallon. I heard mixed results from people giving their plants cal-mag when using R/O water, so I've experimented giving it some that day and just giving it plain water.
Here are my readings from this past week:
May 2nd:
3tsp Big Bloom
0.5tsp Tigerbloom
1tsp Cal-Mag
Mixture (684PPM, 6.10PH)
Run-off (837PPM, 6.27PH)
May 3rd:
1tsp Cal-Mag
Mixture (316PPM, 6.68PH)
Run-off (608PPM, 6.56PH)
May 4th:
3tsp Big Bloom
0.5tsp Tigerbloom
1tsp Cal-Mag
Mixture (531PPM, 6.24PH)
Run-off (822PPM, 6.39PH)
May 5th:
1tsp Cal-Mag
Mixture (317PPM, 6.72PH)
Run-off (530PPM, 6.62PH)
May 6th:
3tsp Big Bloom
0.5tsp Tigerbloom
1tsp Cal-Mag
Mixture (600PPM, 6.59PH)
Run-off (822PPM, 6.39PH)
May 7th:
R/O water only (82ppm, 6.49ph)
Run-off (230ppm, 6.53ph)
My question is, is this normal for the PPM to drop this much? I've tried looking it up and didn't see any answers on this, but did notice that people say not to feed it every time, and never to give it more than the feeding schedule says.
Here is a pic of one of the plants in question, Sweet Island Skunk (78 days old).
Thanks in advance!
