PH measuring for Organic Growers
If I’m growing organically, do I measure my PH still? I heard that the PH up & down liquid isn’t organic & that organic growers should throw away there PH meter because the soil will adjust to what ever PH level I water them with. Is this true? I’m having a cal/mag deficiency.

Molasses
Molasses when watering or no ? I know people use it for compost tea & flushing but I’ve been using it in my water (1 tbsp) for past few watering. Should I do this or just use it for flushing?

Adding DWC nutrients during the week?
I flush & add nutrients once per week, and I can't seem to find specific info on adding additional nutrients during the week. Say I start with my basic ratio for the week, and by mid-week, the water is lower. Do I use the same ratio for 1 more gallon or just one specific nute?

Nutrient lockout? [first grow]
My plant’s started showing signs of nutrient burn, so I have flushed them with just water, after 1 day they turned to worse condition than before. Is it nutrient lockout? Or just deficient? Appreciate every feedback!

Soil getting less
As everybody knows, when we watering soil, it gets more less in every watering. If I add soil when it gets less, will it be a problem ? Because I'm using Plagron Light Mix, it has fertilizer.

Is everything ok?
I am not sure if my plants are growing well enough. It's in the middle of the third week. Could anyone advise me if I am giving the right amount of nutrients to the plants? I have everything noted in the diary. I know my pictures are not the best, but you can still see the size
