Deficiency ? What type?

Hello, I am growing in Fox Farm nutrients and is following the feeding schedule on the bottle. But my plants are showing significant nutrient deficiencies. Can someone tell me how to fix the problem. Ps I don’t ph my water because I lost my ph meter in move.

What do the roots look like? I had a situation pretty close to this and it was because of root problems.

Simply bad watering....
When you water. You need to water completly. And drain the soil.. So chances are tath many time when you water a lot if the root mass remains dry. So when it happans the plant gets only partial of feeding need. You can see this after you water.. You remove the whole root from pot and check if there is any spot that are dry. Water till its wet every where. Abd you have a compkete water. To many poeple under water ( not enough when needed) and over water (dont let it dry enought after.) partial water (only water the top partvand forget about underside roots)
Get this in check. Fast

Ohh and buy the way its normal that fan leaf that arent attached directly to bud side dies. As long has the process is very slow and you still have lots of fan leafs. Then dont over correct anything before checking either roots or watering technic.. (i dunk my plant compketely under water once in a while to nake sure i have a complete root watering oncevin a while..
