First DWC, first LED

Welcome to team DWC MrMuchies! Firstly your air-pump setting can be low/medium. It really comes down to having a good air-stone! Maximum bubbles for maximum Surface-area/oxygenation! Second - I noticed your PH is at 6.3. DWC plants want 5.8PH typically (more specifically a range of 5.6 to 6 PH)

Ok , Plants have a " Wellnesstemperature" its between 22-27 Degree. Under 20 Degree/Celsius the Growth slows down. Over 28 Degree the Plant is stressed and slows down too ( and more) Your Goal is to his the Space between to have an Optimal Grow. But it not only the Temperature. Temperature and Humidity goes Hand in Hand. they depend in each other. Its called Vapor Pressure Deficit (VPD) there is anice Chart where you can look wich Temperature and Humidity you need in each Stage of your Grow. I will post it in the Comments

Hey there MrMunchies If you do wish to utilize a booster of this sort I highly recommend ensuring your roots are healthy and able to utilize the beneficial gains of added sugar! People have been known to start sugar supplementing as soon as flowering starts, but like I said I from my personal experience its best when your microbial life is on point to utilize the boost given by the added sugar! For DWC and hydroponics a simple product like "recharge" can help you achieve getting these microbes to the desired levels. Adding sugar at the start of flower with microbial life is the optimal move to make. Best of luck with your grow @MrMunchies feel free to ask any follow up questions you might have! 😎
