Deficiencies

What is your Relative humidity? Reasons this could happen: -Too high humidity -over watering -nutrient burn

Mmm. I can’t see most of your diary info (my fault,shit phone) but I grow in coco so I’ll answer you with “should do’s” so if you already do what I say then you’ll know why . I wouldn’t worry about over watering much as you are in coco with perlite. It would be hard to over water. At that size they won’t drink much and this is why your pot feels like it’s not drying, when roots expand they will start going through it. Now coco should really always be wet. Feeding at a minimum once per day. If you can’t get to do this then consider automated feeding but at the least make sure you are feeding light. As water evaporates, nutrients are left behind making the ec in the root zone increase, hence resetting every time you feed. Check your ph. It wants to be 5.8-6.2 The pale look suggests she is hungry. Increase your feed slowly, watching leaf tips for burn. Scale back if this happens. Autos usually want less than photos and less is always more but the paleness says she wants more Temps 22-28 Rh 60-70 decreasing as you go on .
