Watering in week7 of flower - trainwreck how and when to water

How have u been watering, I'd say about the same way

Depends on medium, etc, a lot

Go by weight. You should know how much water your medium can hold at this point. Next time you water lift the pot. Judge the weight. Feel it every day to get an idea of how much water is left. When the pot is dry it feels almost weightless. So find that timing right before it’s totally dry. Another method is to finger the soil. Water when dry to the second knuckle. Your plant will change its watering needs throughout the flowering cycle. Up to you to get into synch with its needs and it will reward you.
