I did just do a flush because this started happening after I fed them for the first time and thought it may have been nute burn. Otherwise I was watering every other day at first. (To much) I cut back to every 3 days now.

Thanks for the response Emilya.

Feeding once a week with water that is 6.5. Checked soil ph with my probe and it reads between 7.3 and 7.5

Thank you for the response as I am a new grower.
