ChemCookies - First Grow

I can see them fattening up now. ChemCookies might need support when buds get heavier. A&B stems could hold a pound each or more they are so thick. ChemCookies is developing a slight orange/tangerine scent. Everything was normal last week. Did usual solution add back & feeding. All other environmentals remained the same. Water is clear and fresh so no need for a weekly change out. No film on any lines or walls of rez. I'll do my two week water change out as usual next Wed.
