ok one of plant is doing real bad not sure why and i dont how to make it recover since i never seen this and i keep the ph at 5.6-6 and gave it a tsp of nutes as recommended but it just turned this color on this pic and wont grow anymore
looks like a zinc dificiency, flush the plant with a diluted nute mix contaning zinc, iron and manganese elements.
also calibrate your PH meter as this could have caused your problem.

would this work for hydro??
since its a deficiency and this article came from a marijuana guide..would dropping them in the water work?
ZINC (Zn)
White areas form at leaf tips and between veins. Occurs in alkaline soils. Zn deficiency can be treated by burying galvanized nails in the soil. Chemical fertilizer containing Zn can also be used.
what are you growing in? i would flush the growing medium as long as it is not a bag of miricle grow or anything similar, keep us posted on your progress!
