The white widow is looking nice. She got watered once this week and first feeding of cal mag and kelp. Also gave a little coconut water to help the root development. Showing slight variegation but looks like it will shake it off in the next week.
@PandaNugzzz84, Hello they are soil moisture meters. The are called ecowitts. They have AA inside and send data to a transceiver that's hooked up to my wifi. cost around 20 dollars each and the receiver is another 40. Can't judge completely by the meter when to water but they do help,and also keeps a record of every time I water and all kinds of data
