started grow question 6y ago
Is it safe to lower the water PH with freshly squeezed lemon juice? Tap water is at 7.5, I am thinking of adding lemon juice to bring it down to 6. 5.

When and how do you switch from Canna Vega to Canna Flores? Feel free to share any tips. What are your "signals"? Do you suggest a hard switch like in the Canna schedule, or do you prefer transitioning by mixing the fertilizers? If you need more info, please check the diary.

To much N?
To much N? Fan and sugar seem darker green thinking I gave them to much N, used all purpose along with powerbloom, I'm thinking of cutting out N completely and relying on 2-8-4 instead for my fast autoflowers. Thoughts? Amnesia haze auto and purple Kush auto fem canuk.

Tap Water PPM
What PPM does your tap water come out at? Mine comes out at 380 with a pH of 8.5. I’m pretty sure that means I don’t need to use any Cal Mag.

How to make stronger smell and flavour in DWC grows?
Hi guys. Just harvested my second ever harvest, and 2nd time with DWC. Using HPS, then CMH for last 2 weeks I'm really happy with buds, but the smell is a little less intense that I would like. I have used Cannaboost, which is supposed to increase flavour but I want more! :)

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?
