First couple weeks of growth i dont water much. I ysually dont even water to run off until about day 24 or 25 after germination. right before they start to stretch. Try to water to 10-20 percent runof Out of the bottom of pots. Being organic nutrients i shoot for 10 percent range with biobizz. I run multiple strains and each one eats at a different pace. Right now i got one that needs a half gallon a day. Guess about 1.5 liters. And another one thats taking a half gallon every 36 hours or so. Feel the weight od your pot after watering. Check it daily based off weight yyoull know when to water. Yours just starting to flower im sure shes gonna be wanting a liter kinda often. But every strain is different. And phenos lol
