You should only use 50% nute loads to prevent build up in the perlite.
At first they will only need water about once a week,
depending on the temp/humidity in your grow space.
Out door they can dry up in a day,
indoor they usually only need some water with nutes about 1 or 2 times a week.
It is very important to not overwater.
You need to let the rez dry out
before adding more water with nutes.
I let the plant wilt to tell me when it is time to water.
If you use RO and AN 2 part nutes without
you do not need to adjust the pH
as it will be 5.6
If you add fulvic acid you may need to adjust the pH up.
This is a really good way to search for that great mother plant
and grow hydro without much worry about rez temperature.
