am i over feeding

hey guys a i over feeding, there at week 5 of flower sky walker OG kush they had just been fed but im scared im over feeding my ec isnt up to 1.8 its around 1.4 and i only feeding the on inial dose on dutch pro A-B but im getting clawing on the leaves and they are really dark green cheers

by the way i have heard a few people say that this strain is nute sensitive thats why i kept the dose down to 250m instead of 3.5 ml per 100l

A little less N would be nice.

okay cheer buddy would you just reduc A-B or flush for 3 days then reduce Nitrogen also

You have "N" toxicity - plant looks like a claw and is dark green in color - Remedy: flush then readjust nutrients and use of per week - also at that time of flower no "N" is really needed - just P & K - there are 3 stages of flower : early, middle and late - each stage needs a specific N_P_K. Nitrogen issues is a common problem with many growers

what is the ratio for each faze of flower harris hawk cheers buddy
