A question from a fellow grower:
The 10 seeds arrived, and I planted 6 of them. So far 5 have sprouted!
My problem or concern is that those that have sprouted and are about 2/3 inched tall, roots beginning to grow out of the bottom (hydro method), are turning yellowish - the leaves…?
My PH level is 6.
Here is some information to help in your review and comments regarding the yellowing of the leaves.
Hydro grow system
Light on for 18 hours, is this too long?
CO2 booster (adjusted to high yesterday)
Thrive Alive B-1, red, per instructions (mixed with water - distilled), added weekly for 3 weeks with all new water
Water level just below grow cups
Light 48 inches above top of plants
Small fan on low
I’m a first time gardener, and perhaps I don’t understand:
At what point are the plants in vegetative stage? Age in weeks from sprouting, a certain height and/or a certain root structure/growth?
