Im 3 weeks away from harv.. i think it zinc can anyone help?? using a 600 hps, temps allways in 70's, humidty 40'-50's, keepin ph around 6.5 using liquid ph tester(i might have been adding to much ph up and it could be slightly above 7), using FF nutes grow, tiger, big bloom ( amount FF scedule says to use) with watering every 2-3 days, have in vent and out vent but air gets stale from time to time in room where in vent comes from

looks like your fan leaves r doin what they do naturally in the late stages of flower could be wrong tho but plant does seem health everywhere else.

the tips of majority of the new leaves are yellow then browning around the bud.. the whole crop is way to yellow
