Hi MMJMD
I using one off those
HM Digital COM-100 Waterproof EC/TDS/TEMP Meter
since last year for my Family garden off Tomatoes, Cucumbers and salad grow.
And since then used it a few times on my grows marijuana grows.
Pretty accurate but a bit expensive.

Help!!!!I messed up and forgot to set my light timers back. I started a new grow from seed and have been running a 12/12 light schedule for 17 days. Is it too late for veg? Can I switch them to 18/6 or 24 hour for vegetation or are they already starting the flowering process? Please help

Remove more leaves or notShould I defoliate more and remove small buds, or is it better not to stress the plant during flowering?
Also, why do the two plants on the right look so different? I didn’t do anything differently

Question regarding humidityCurrently, the humidity in my tent is ~55%. The plants are in the early flowering stage, so I am worried about mold. Does anyone know if the humidity is too high or can provide a solution without an electric dehumidifier?
