Whats my Deficiency?

Soil is too hot.........leaves are burninig, not showing signs of deficiencies...........a soil mix with a N/P/K ratio of 20-27-27 is insanely rich and not really suitable for cannabis.

overfeeding, plus i see magnesium issues, either wrong watering regime causes it, or you overdo things.

looks like n might be too high locking out K or maybe K is low and n is only a bit high. leaves are dark and glossy at bottom looks like start of n buildup, and the chlorosis around margins looks like K-def. the wavy leaf is likely caused by some ph-swings impacting rate of growth. So, ensure pH is proper.. 6 for soilless and 65 for soil are good targets to stay within a few tenths either side. is that water on a leaf? using foliar sprays? Stop doing that unless it was directly in reaction to a problem you are solving. Otherwsie, foliar sprays are more akin to masturbation
