I went back to the regular lighting schedule (18/6) for this week because it was warmer outside again.
I did stick to last weeks feeding schedule but only give them nutrients like 2 times a week, the other watering I just use PH'd RO with Calmag.
New leaves started growing. Some smell emerged also this week.
I moved the lamp a little closer also and they seem to like it.
After trying to give less water and making it worse. I tried giving them water again, making it even more worse than it was, I found out is was a potassium deficiency. After giving them nutes they started to come back up again.
