What are your daytime / nighttime temps

Day / night RH

What type of light and how close and power setting atm

Assuming no neuts added since you’re early in happy frog but what have you used up to now/ what neuts do you plan to use

Grab some more pics of the whole plant as well

What are your watering practices, how do you decide when to water, how do you physically water the pot are you slowly adding water then waiting a few minutes then repeating, how do you decide when to stop,

Lots of variables to look at but start with basics and see what you have for a setup
