yellowing of top leaves problem

Well i noticed after i fed a couple days ago i had this yellowing on the top growth between some of my leaves. idk if it's progressing down. or if its light bleaching or a nute def.

Please help if you can though, thanks.

You've got a nute burn. Are you ventilating with only an exhaust fan? If so you'll have to compliment it with an equal intake fan.

yes intake and exhaust. didnt look like nuteburn to me. since it started at the top cola. no other branches are affected by it.

might be though, ill flush.

you have to lower ph or plant will shit it self completely imo.

You have Ph issues. Better pics would help confirm. Also looks like a zinc deficiency.

i use 6.3 everytime though, i flushed with 6.3 water though. hopefully it will bounce back quickly.

Are byou checking the runoff?Are you using mg soil?IF so you might need some cal/mag thats what i was told because mg doesnt have much if they have at all.

i have similar issue...getting ph soil tester..not the home depot special.....hope they servive until then and grow nicely!

yea i tested the runoff it was around 6.5. that plant has ffof and mg peat moss

Classic zinc deficiency..................
