Deficiencies at Day 60 or natural, expected fade?Does my girl look like she is suffering from a deficiency or is it a normal fade for day 60 since sprouting? What can I do as she definitely has a while to finish I feel? Any estimates on how much longer she has before getting close to chop? See most recent comment for details.6y ago

I think I'm closer to week 7 of flower than I am 6, debating if I should flush.. The girls leaves are slowly burning down the sugar leaves closer to the bud, so I'm wondering if it's too early to flush.. Everything looks pretty good other than that, I think..Week 14

Why do leaves turn yellow and dieDoes this look like underwatering, heat stress, or any kind of defficiency? Also might be rootbound, cause I used not a lot of soil which also makes water evaporate faster.
I water 0,8L/2 days pH=6.3=runoff, If its hot some leaves start to droop in less than 48h after watering.Week 8
