Took a look at the hindu. They are small. Looks like a possible ph problem. Therefor, they aren't getting there nutrition. Or nute lock out. They need flush immediately. What are u using to check the ph? A digital meter is the best. The strips and drop kind only get u close. For pot, close dont work. As far as the pistols go, thats about right. On autos, those pistols show up within 2 weeks. I didnt have scale big enough to weight em at the time but I'd guess on average about 30 grams or so per plant. One of my hindus was a runt at 14" so I'm pretty sure they were around 2 to 2 1/2 feet tall. Later dude, hope this helps.
