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.
My wife is keeping it close.

Hopefully I get back lots of "Don't worry! it will be fine" replies!There is a brown resin coming from where the cotyledon leaves are/were.
Is this something I should be worried about?
It's no. 2, so she is the last one I should be worried about 🤨

Reducing PPM without changing water in hydroThanks all for guidance on my previous question. As a follow up, can PPM be lowered by reducing feeding until they hit the right range? Currently 1500ppm but seems this is too high. Currently following the AdvancedNutrients plan.Other. General questions

When could I start to harvest?When do you guys think I could start harvesting? I’m in week 9 of a Fast Eddy CBD grow. This strain only had 9% THC so I didn’t know if this would mean the trichomes don’t go as milky.
