What are u growing them in ,what medium and what nutrients are u goin to use ,ur plants look good
Plants look fantastic. As stated above what medium, what nutes are you using, and what age are they? I’m guessing 4 to 5 weeks old by see the preflowers. Welcome to this amazing community!
Same as the others asked. Medium will determine that 
Welcome to the forum.
You should be measuring runoff PPM to determine nutrient needs. Get yourself a PPM meter and maintain a level of ~1,000 with your feedings. It can be a bit clumsy at first, but you’ll eventually get the hang of how to maintain 1,000.
Those are 2 gelato auto and 3 banana kush auto. Using coast of Maine organic soil. Added more perlite. Humbolt secrets nutrients. Ph my water to about 6.2 - 6.5 before adding nutrients. And they are about 5-6 weeks old. I’m feeding them about every 5 days with a watering in between. Should I be feeding every watering? I’m using the starter kit with Added sweet and sticky also.
4 going on 5 weeks.
If you have a tds meter you could measure some run off next feed and see where you stand. From the looks of the pictures I do not see any deficiencies so my suggestion would be to keep doing what you’re doing. Keep an eye on them and if you start to see any deficiencies you can make changes then. Are you following the feed schedule according to your nutes?
Me personally i would feed them every three to four days but thats me
Tezza is right on the money start watering every 3 days , if they start looking wilty back it off to 4 days
I hope you mean AFTER adding nutes?
Are those nutes Ph balanced? Do they hold the same Ph as before adding? Most don’t.
Adjustments to the Ph should be done last before the water and nute solution goes into the container.
I think the only thing you can add post Ph adjustment is microbes for the soil, but I’m sure there’s a million opinions on that…
Otherwise your girls are looking good and do find out what your run off is doing.
