The 15 beginner mistakes — and how to avoid them

Experienced growers say: 'I made every one of these mistakes — you can skip them.'

TL;DR: Top mistakes: overwatering, no pH/EC meter, bad climate, overfeeding, panel too high, harvest too early, drying too fast, no cure.

1. Overwatering

Roots need oxygen. Lift the pot: heavy = wait, light = water.

2. No pH meter

Bluelab $80. Without pH = guaranteed lockout.

3. Overfeeding

Start at 50 % of label dose. Raise 0.2 EC/week.

4. Climate

Day 22–28 °C, night 18–22 °C. RH 40–60 %.
