What is this deficiency?

I wont blame humiddity, Hemp grows under nerly every condition// but better under perfect I see aimbalance in your grow but if i look at your numbers i dont thhink it is adefiency you amended your Soil with the nutrients=? normally she should show no defiency There are 2 things remaining. sahe looks like burnt in last week already...... and she grows very short with small internodes soo your light may be to close or your PH is wrong, that she cannot uptake the nutes II would start with risng the light too at least 30 cm and look how she reacts...... older leaves will get worse, but new leaves should grow nice and green contact me per DM we can talk
