What is safe RH level during early flowering?Looks like weather's gonna be a bitch. Forecast for next 10 days is 65-75% RH. Now it's 60 indoors and 64 in tent. Got some silica gel in tent, next I will put portable AC/dehumidifier next to tent. What would be good RH that I should aim for?Week 5

How long left until I can harvest or flush?Hey, first time grower here. It's been almost 9 weeks since she started, on the seed this one is supposed to be ready for harvest in about 8/9 weeks.
She is really small, didn't really grow well but I'm seeing a lot of brown pistils and the end of leaves is yellow.
Thanks!

Flushing or NotDay 58 for P1 and buds swelling nicely with pistils turning amber on about 50%.
Not sure whether to flush or keep feeding. Not sure exactly how many weeks left but guessing 2, possibly 3?
I don't mind the smoke being a little harsher and not sure if flush will = low yield

HOT as a MOFO ;) Need advice please.I've been struggling with high temps (88-90F) during the day mid 80's at night. It's been difficult to find a cooling system in stock that meets my needs. If I'm unable to bring the temp down below 85F what is the most ideal humidity for my plants, what are expected issues? TY :)

Yellow edge with brown spots on fan leavesI am wondering if anyone could help me figure out what is going on here. She’s been healthy all grow, but in the last week has started showing the weird yellowing/browning on a few leaves. The temps, nutes and light haven’t changed really. Anyone have any idea what this could be?

Deficiency helpWhat deficiencies are these? I’ve flushed her, ph’ed her water and I’m giving her a good amount of nutrients - no nitrogen for the past two weeks I think.
Is this just an age thing? I don’t need her to look perfect before harvest, but I’m afraid it’s affecting the bud maturity.
