I’m in 20l fabric pots and I’m giving them water at a ph of 6.5 atm as I was giving them nutrients but they have just starting showing signs of nutrient burn ( yellow tips ) so I’m going back to just plain ph water until I flip them next Monday then going to give them half strength nutrients hope this will help with yellow tipsThis is for soil based growing and the idea is not to feed the plant until the plant has eaten most of the nutrients available in the soil.
After that you can feed every time you water because the plant needs to eat and the soil has no plant food left it can provide the plant.
This is when you can feed every time but you also don't want to feed more than 600 ppm a week if you grow under a 600 watt light for example
it's like if you have a 1000 watt your limit is 1000 ppm etc.
So i use a 600 hps for our medicine needs and usually after a month of having roots in their final bucket i feed 600 ppm once a week.
if you need to water more than once a week your in to small of a container for soil media grow.
you wanna be in a container just big enough to water once a week that's the trick.
