whats wrong with my ak 47

this is my first grow, i have 2 other ak 47's that are growing fine but this one is going a little slower then the others and has these yellow tips now that were at first for awhile only light green tips. and theyre only on the new growths.
my inexperienced guess is magnesium deficiency from reading a couple things but yeh what is it?

if feed my plants botanicare pure bloom pro veg/flower and liquid karma. but since this one has been showing signs i have been giving it slightly less nutes then the rest just to be careful

what is the ph? i also see a little red starting on the leaf stem

NOT Mg deficiency........burnt tips probably mean too high nute concentration. Plants are very green so that's my guess.

Many people say this can be a difficult strain to dial in.

Edit; Flush your pot with 3 times the amount of pot size with plain ph water. Next watering take off 200ppm off your nute concentration and start climbing back up. Some brothers and sisters don't grow as fast as their siblings so plants are similiar.
