Name the deficiency.
Problem is mainly occurring on leaves near the top, but not the newest growth. Initially are less green, then start to yellow followed with brown spots. The oldest leaves near the bottom are seeing some effects, but as acute as the mid-upper leaves. Curl likely due to warm temp

On Week 11 Day 74, I've been noticing the leaves turning yellow. I'm assuming because we're getting close to harvest, but after reading more about nutrient deficiencies I'm wondering if I should be doing something about it. I started flushing a 1.5 weeks ago.

Help! Timer problem.
My timer on 18-6 broke and i'm not sure if the girls had 24 hours for the past couple days... by putting them back into 18-6 will that trick them into flower? Hope not. Thanks :)

Light spectrum during veg and bloom periods
I have 2 1000w full spectrum lights. Each light has 2 switches-a veg button and a bloom button. This gives 3 settings for the lights-veg only, bloom only and both lights on at the same time. What settings should I use during Veg and during flower and how close should I hang them?

Can I use magnesium sulfate foliarly?
Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect. I should add Dolomite Limestone to the soil this week.

11/13 for flower
I need my grow to finish flowering ASAP, due to extenuating circumstances... I’ve read that flower can occur faster under 11/13 with some loss of yield. Does anyone have experience here? How much will yield and flowering time be influenced?

Novice grower, Outdoor. Started in a 70/30 coco-coir to perlite mix. Forgot Worm Castings until 22nd June, implemented with top dressing of Gaia Green Power Bloom and All Purpose. Overwatered at stem for a week or so. I suspect it's either an N, P ,or K deficiency (nuteburn?)
