When the amount of the nutrient solution drops below one gallon, the solution becomes more concentrated as plants absorb the nutrients. This results in widely fluctuating pH levels.

Plagron sugar royal - hermie´s
Could plagron sugar royal cause plants to hermie? I have used sugar royal for 2 grows and in these grows, always 1 or 2 plants went hermie. Before I have never used sugar royal and I never have had any hermies. Sugar royals creates a kind of drought stress to increase trichomes.

Co² tabs for water feeding
Do you have experience with CO² tabs? This manufacturer says 1 tab is enough for 100L (=26 gal). The particles attach to the water and uptake is through the roots. They said overdosing is not possible but should be cautious with PH of the water, also after adding fertilizers.

Water uptake slowed considerably. D83 DWC Auto.
Water uptake has slowed considerably this last week. From what I understand this is expected as she finishes her life cycle. Should I continue res changes at full strength or lower the nute ratio to match her uptake? Trichs are still clear/cloudy with little amber.

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.
