Look good! but a little hungry
Which botanicare product ya using and how much ?
Do you water to runoff? Able to get runoff ppm ?
Each plant will be different I see one that shows signs of nute burn , the dark green is a sign your feeding heavy . Then there’s the light colored tall gal! She needs a little more I think ,
If ya give more information more people will help

Medium, nutes, water schedule, ph, ppm ect.

Ur on the right track man. I wouldn’t change much for this run , if anything I would feed more often, Not necessarily more.
I would grab a cheap ppm meter so you can check parts per million, it’s just another tool that help you a cheap $10 meter will work
I use pbp grow all the way thru as well

The tall skinny girl with the burnt tips could be a different story , might have some kind of lock out starting ? Or did you over feed this plant at some point?

No I like the fact you let her dry out just try to add the nutes every other watering instead of every third .

2 ml per gallon of pbp is not nearly enough. I fed at least 10 ml per gallon in flower. Larger plants 15 ml.

And it works best if fed every watering with some fresh water only once in a while to wash out built up excess.

Most autos are lite feeders I use 6ml most of the time

Mine took 10 each time from stretch on and 5 plants under a 600 hps yielded 15 oz on my first grow ever.

I use 5 ml of pbp for seedlings and when finishing.

Even 10 ml doesn't include enough ppm nitrogen to keep a decent aize plant green in my experience.

You might get a lot more plant and flowers if you up that some.

You’ve seen my fried stuff, lol, so I’m on the lite side now, and the current run I got goin I used eight and it might not been enuff , I shoot for around 800 ppm at the end of stretch mayb I’ll up a couple and see what’s happens with the next batch

Maybe we are misdiagnosing deficiencies. Its hard to know everything going on from pics and comments.

I couldnt get to 800ppm (1.6 ec) with 6 ml even fed every time. And i dont let plants stay that high ppm anyway. Target 1.0-1.5 ec for me.

Try feeding a plant like you have and pick one to increase to see how it goes in your room.
