They all look so happy in their new homes! It's kind of hard to believe they all fit in one tent. It must have been an even tighter squeeze than it looked.
Not to be a Debbie Downer, but do you know what is causing the edges of your leaves to fade on the Chemdog and Amherst Sour Diesel? I'd like to lock the answer away in my drafty brain vault.
I too would love for you to have the answer just locked away in that brain vault, drafty or not. That discoloration has bothered me too and I suspect Magnesium deficiency but it could be Calcium or even Iron. On ASD, I did note the leaf tip has some burn but this is just one of those things about growing different strains and using one mix for all feeding in the tent. Now I'll mention three other things: 1) Fan blowing directly on a plant 2) Temperature swings 3) Light damage.
Short answer is I don't know. I am fussy about pH inputs but I haven't calibrated my pen in a while.
What pH are you running Jim?
Jim, I hope you don't mind,
Duggan has a new journal up and running. Come join the excitement.

Hmmm. I don't think it looks like issues from the fans or lights. Temperature swings can certainly cause issues but I agree with you that discoloration really looks more like a deficiency of some sort. Maybe hit them with some extra calmag and see if it helps? I'd really love to know so don't forget to report back with whatever you try please.
The very first step is to check the calibration of the pH meter. These devices drift quite often. Don't add anything until you check that out.
MJ,
This yard is rocking!!
