Just want some honest opinions and ideas on when to harvest

Hello RIU, you all have been so beneficial and helpful with all the techniques and ideas given to me here on this site. I started by posting a pic of a closet and here i am DAY 51 of flower. Both were started same time in sub cools soil, only things given were molasses once and epsom salt to the widow cuz I mistook heat damage for a mag def. Since then both have been flushed twice w 3 gallons and watered usually with 2 gallons of spring water. The one on the right is a white widow that clearly shows damage, pics are over head, main cola, the Underskirt shot, lol, and close up nug shot. The one after is a mazar x white rhino using a 400hps and 4 T5grow lights at 54watts, temps have been up and down because of the weather, too cold and too hot at times, just need opinions on what you see for someone at day 51

Roughly another 3 weeks to a month till harvest!

How much supersoil did you use?
did you mix it in with a base soil?
Looks like nuteburn a bit or heat stress maybe?
if you used all super soil then its nute burn.
we need a bit more info.
Whats your temps, how often do you water, etc.
in soil like this, because its organic, you dont need to flush.
you're not overloading your plant with chemicals.
i think you should do a bit more research on the supersoil and your plant strain.
theres an organics/subcool section on roll it up, i think that section would benefit you more.
good luck!
buds look a bit small for day 50

More time, not giving a precise estimate because I have to be honest.

My guess is he's counting from day one of 12/12 so he's mostlikely at day 41

yup, I started 12/12 on Nov 14 in my tent, unfortunately, the temps are so extreme here in NY that its hard for me to get a handle on the temps, thus my thinking of the smaller buds.

I used sub cools cool soil for seedlings and veg, and switched it to the hot soil formula, nuts burn didn't show until almost a month into flower and then I figured it was a heat issue.

My sacrifice is using a room heater (electric/oil) to bring up room temp (now hanging at 77 day time when its 9degrees outside) and not slow down growth but at the cost of the humidity hanging around 21-16%.

For the conditions you are fighting things look ok. You do have a while to go yet though. A wild ass uninformed guess would be 3-4 weeks, but you should get a 30X scope and read the trichs. You will soon learn how you prefer the high, and how the trichs look when it's the way you like it. A very general rule is when the trichs are turning amber from cloudy, but it really depends on your high preferences.....couch lock...go longer. Energetic...chop sooner. It really is one of those things that differs a ton between smokers. You can always cut an occasional bud as they grow to learn what you like. Peace & be kind.
