West Coast OG - 4AM - First Grow Ever

This plant was healthy from the beginning and progressed well the whole time. I had it planted in 5 gallon smart pots and I think I may have prevented them from reaching full height due to hesitation of watering to much and not starting nutes earlier in low amounts. I gave the plants enough water to stay nice and green but with my pot size I feel now like I didn't water enough to let the roots expand and basically created a smaller pot within my 5 gallon. After trimming all the leaves while still potted I then cut the plant at the base and proceeded to trim all the sugar leaves. After trimming I hung it upside down to dry and I will remove individual stems in a couple days. I have low humidity so I will be monitoring closely and trying to achieve a 5-10 day dry before jarring. For my next grow I plan to use 3 gallon smart pots with more plants and watering enough to use the entire pot. After examining the roots from OG#1 I feel my suspicions are correct and feel my root structure could have and should have been larger. I am hoping for 25 grams from this plant but being my first grow I'm just happy getting all 3 to harvest. Overall I think I'll get 65-85 grams from all 3. Edit: 73g total from the 2 West Coast OG Kush plants far exceeded my expectations and made me very happy with my LED purchase (Philzon 1200 from Amazon). I am still considering a HID or CMH but this light is very capable and sufficient to grow some quality bud.
