Nano Grow #4 - Gorrilla Glue

End of week 5 and into Flower. Well I think I can officially stop calling this a 'nano grow' - these girls have grown like crazy the last 2 weeks and show no signs of stopping yet! They stretched so much I actually had to remove my fan and filter and put them on top of the tent sucking air out, and even now I may still run out of space again if they don't stop stretching. It has really shocked me the difference in plant size moving up to 5l pots from the 2l pots I used in the last grow. Trying to decide whether to defoliate or not, maybe it would help slow down the upward growth, but at the same time the plants are looking pretty healthy and happy as they are. Both plants have a nice open structure with plenty of airflow so perhaps defoliation would just cause unnecessary stress for little reward. I also wondered if perhaps the plants were stretching for more light so I checked with PPFD app on my phone and they were already getting a DLI of 55-60 at the tops! From what I understand that is much too high without proper environmental control and cO2 supplementation so that can't be the cause. I guess they just want to grow tall! Apart from the stretch issues I am pretty happy with the plants, they look nice and green and healthy, only the left plant which suffered from pH/nutrient issues early on is about a week behind the plant on the right in terms of bud development.
