Dropping Leafs??

Looks like overwatering & nutrient lockout. Can you tell more about Temp and Humidity in grow room, are leaves feeling crispy and dry or heavy and wet?

Looks like nitrogen toxicity to me. I am thinking your soil is too hot with available and fast acting nutrients. Of course, it can always be other things. For example, if water is not pH corrected, or other stressors happen to the plant, it can stop absorbing nutrients.

Hi there As said below start a diary and we can know more of how and what your doing… But looking at the pics shes over fed and over watered, i would flush with just water and let her dry out until she perks up then adjust the feeding schedule Best of luck 🌱

Chronic nitrogen excess.

Like others have said it's hard to diagnose without a diary, it does look like you have issues with phosphorus and potassium.

Hard to say with just a picture. Medium/nutrients/pH. My guess is root issues from to much water and/or nutrients.

Granny nailed it, need a journal, try to put one together, or just do better job tracking next time. The journals here are a tool, a resource for you to utilize. Right tool for the right job, and tracking info is the best way to learn. Best, The Fatty McCoy

If only you had a diary for this!! This poor plant has had far too much nitrogen and is now showing terrible signs of a potassium and phosphorus deficiency... but I can't tell you what to do about it because I don't know how you've grown it so far - what nutes, how much, what your pH is, all of these things will factor into the causes of what's going wrong here and would then point the way to correcting them and getting this poor lady back on the right track... Sorry!
