#1 is not showing any sign of flowers or preflowers, it is showing some bleaching leaf tips and frankly I am not certain it isn’t a potassium deficiency, otherwise its a pH issue. It’s definitely not nute burn because it’s not had much in the way of nutes. I am moving the light up to 30” above the foliage in hopes it causes her to stretch out those nodes a little more
#3 is an autoflower, it’s got a smaller stature and gorgeous little pom-pom buds starting.
#4 is an autoflower that appears to be sativa dominant in its structure and bud formation. I’m impressed with how quickly it’s grown. It is nearly as large as a photoperiod I started 2 weeks prior to it.
@DaenerysT, I’m totally blind as to what they are. #2, 5 & 6 are here waiting for another grow.
I only had room for 3 this run, if I run them on a quick veg. I let the spouse choose which ones to run this time. I’ll do that with one seed of each tester. That will tell me what I’ve got for general structure, and then I can go back and run them again and train appropriately to maximize their yield etc…
