When should I began to flower?

Hi—- you can flip it. However, they are looking a little overwatered! Good luck ✌️🏻💚🌿💨

I'd personally veg them for another couple of weeks will give you a better overall yield at the end of your grow . Also tip don't spray your plants with any form of liquid when the lights are on it will damage them and stress them out x hope this helps x 💚 Happy growing x

5 weeks is not an unheard of amount of time in veg- however it’s recommended that you give the plant its best chance if you give your plant time to bounce back from stressors before hand. Considering she had a period of under watering, and an overdose of nutrients I’d give her a week or two to bounce back before the flip. 🌱

General idea is to grow them half the size YOU want them. They can double or triple in stretch when you flip to flowering.
