Is this in danger of etiolating?

My one cactus on the right here has taken on a somewhat pointy shape whereas my other one remains more stout. I was wondering if this may be in danger of etiolating and what I should do about it? The pointier cactus seems to be growing more quickly so I wanted to make sure this won't soon become a problem.

Is this ok or is it possibly etiolating? What do I do about it?
 
Increase light.
If the increase will be a substantial one then stop watering as you gradually increase the light to both reduce sun burn and reduce etiolation in the adjustment period.

Quick update, I wanted to get another opinion on this. The top picture is the cactus I was most concerned about etiolating, and I did as you said and increased light and stopped watering. However it seems to be pretty thin still, I dunno if I should water it or what. The bottom picture is my other cactus which seems to be growing somewhat thin but still looks better than the other. I gave it a little bit of water a few weeks ago as I was worried the roots would bake in the hot sun. It seems to be growing alright but I am not sure if it will thicken up.

Please help! I am still learning how to deal with these things. They have gotten plenty of sunlight but are growing in odd ways.
 
If it's getting enough light, give it water too. IME, you only want to back off watering when it's going into dormancy or coming out of it. When it's growing full on, I give it as much water, light, and food as it will take.

PS are those bridgesii from an auction seller? I have one that looks quite similar.
 
Thanks, I figured they would need some water. I gave them both a little bit of water this summer but I tried not to give them too much. I'll have to give them some more.

I PMed you.
 
Here's mine, planted in May and rooted/started growing in June. It's narrowed a bit, but I feel that's generally to be expected given the difference in climate and space for roots. Or maybe I'm just doing it wrong...

I would say it is OK - the difference in colour shows fresh growth, which is not always the same diameter as earlier growth - and sometimes they can fill out in time anyway.
 
They'll appreciate a few feeds with half-strength organic tomato fertilizer next year, I'd say. I water my Trichs generously throughout the summer and mist them too. The grow amazingly quickly, I've literally run out of space for all the cuttings (in my own home, at least.)

IME - the etiolated cacti tend to fill out a bit, so long as they haven't switched to producing ultra-fine spines. Those parts stay skinny but the cacti switch back to normal growth when conditions have improved and they've cheered up a bit.
