What kind of deficiency is this?

Hi there, Four things come into my mind.It could be one of your problems.1) phosphorous def ( purple stem and leaves).2)light burn ( top leaves which exposed to light longer than the others have this symptom.3)Run out of food ( if your run off ppm is 250, definitely running out of nutes).4)genetic ( some strain will show tips burn like nute burn.But on the other hand, they cannbilize themselves and the leaves will be turning into yellow even though you are giving enough food.Happy growing... ✌️

Cal msg them ladies. That is a nutrient lock my ladies did this at week three of flower and they straightened back out. But it’s cause of the soil ph not adding to the ph of your waters intake at root level.

Looks like manganese deficiency. Here's a link for leaf problems. https://www.growweedeasy.com/cannabis-symptoms-pictures

Could it be some kind of combined deficiency? Nitrogen (Yellowing) and Phosphorus (Yellowing starting at the tips and necrotic spots) maybe? I´m just a bit confused as i fed the plant with a 1000ppm / 2EC solution of 1-3-2 blossom booster over a week ago, which gave the plant the burnt leaf tips. The right plant has no problems at all and it is the same genetics in same soil, pot and lighting. It had a bit less feeding, yet has a slightly higher runoff EC. I have 1-3-2 and 8-5-8 fertilizer at my disposal.
