Still a nub chose auto flower for faster easier grow I’m a busy guy in the summer. Picture I’m posting is to show the complete difference of look but same strain and pics of what’s going on with one of them. I’m using fox farm trio plant food big grow and big bloom. For x farm ph control dirt very airy and smells like camp… lol. Tested ph in both when I noticed a problem with one … 6.8 for both. Rinsed the down to 5.3 next day back to 6.8 so besides the plant food food from fox farms just giving that plant water. The other has not had any bad reaction and they s growing from what I believe good. The one with the problem has slowed in growth has a lot of leaves compared to the other the tri colms said that wrong are crazy big and many leaves not very large. Planted them same day together I did use some ph down very water down don’t see a change
Every plant is different, even with same genetics, like people. I did 5 of the same strain, same breeder, and have 4 different types of plants 
Hopefully more experienced people will chime in, but I wouldn’t worry about it too much…
I’m new but I have 3 of the same strains going at same time. 2 are short bushy and have 5 tipped leaves. The other was lighter green, tall and 7 tipped leaves. Also even between the 2 that are similar, one has ridiculous trichomes already but not fat yet, the other has less trichomes and way fatter. The tall one I mentioned I actually asked someone if it was a different strain it looked that much different lol. Everyone has its own unique traits from what I’ve seen so far.
@Evilmendo I agree with the 
others. Your plants look fine in the pics and the subtle differences may just be their genetic individuality. Keep posting and we’ll track along with you.
Thanks to everyone who chimed in … they are doing great. My worries got the best of me. Here is a pic on progress
@Evilmendo glad to hear!! I just dropped some of these beans yesterday!!
Just received my purple haze … super excited but have to wait just doing two at a time with new plants at the near the end of the lemon to keep a cycle of plants constantly going.
