You want set it at 5.5 and it'll quickly climb up and try keep it below 6.2. Ideal is between 5.8-6.2 but you can safely be within 5.5-6.5 without too much hassle Happy growing.

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?

Feeding advice.
What should I feed? I'm 2 weeks into my second attempt at a first grow lol. I'm growing an Auto in soil, outdoors in the UK. I'm trying to keep things organic. I've researched rabbit manure which I have and liquid seaweed. When can I use these? Do I need them?

Yellowing leaves/slow growth week 1-2
What would you recommend as the course of action for these girls? I need them to recover quick.... My thoughts are some root tonic? Since giving them last round of nutes, I've just been giving water and recovery is so slow, girls are barely moving....

Overfeeding in flower, Flushing in Coco Coir
Hi my plants are very dark green due to overfeeding: I mistakenly fed 4ml/L of Canna Coco A&B for over a week, although 3.5ml is the recommended amount by Canna Now the buds smell pretty bad Should I flush with water, or just half strength nutes? Would this affect my yield? Thx
