Well things are starting to break down with my first grow and I need a little direction as I feel I read conflicting information online and I have conflicting symptoms.
I have two plants, both white widows, one still in veg, one in week three of flower, both seeds were planted January 8.
They have always “seemed” a little weak, not robust, but they grew. This is what I know:
Turns out I have been watering with 5 to 5.5 pH water since day one. Guess I should have calibrated the meter sooner.
soil is Aurora Roots Green Lite
Nutrients (General Organics Go Box) at 1/3 to 1/2 strength every third watering.
Watering about every third day.
5-gallon fabric pots
Light On temp is around 75.
Light Off temp is around 68.
No circulation fans, but exhaust fans run about 30 seconds every minute and a half (so a 25% duty cycle)(anymore than that drops the temperature too low (to basement ambient).
Once I calibrated the pH meter, I flushed both plants with about 3-4 gallons pH6.2 water. Run-off is in high 6 to low 7 range. I never checked the run-off before calibrating the meter.
In my mind I have conflicting indications - tips that look like nutrient burn, but yellowing that looks like a defiency (nitrogen/phosphorous?).
Any opinions are appreciated, I really don’t want to lose the flowering plant… What do I do next? Thanks everyone.
