Day 43 : Watering with co2 tab / 5L. Also added food again because i think they need it. Increased ppm to 850. Maybe the next one will be pure water. Ventilation works all the time when lights are on. Temp and humi are stable and this is good for the girls. Although she is indica, she still grows. 9 cm in 3 days. So i guess this is the reason her buds are a bit behind. Patience is the key always. Also removed some burned leaves from all ladies.
Edit (Day 47) : Watering with co2 tab every 5L. I watered with juices again at 850ppm because i felt that they need it. Only WC drank pure water because of burns. She grow 13cm in 4 days. An indica pheno stretches like she is in preflowering stage. And this i think is happening. At start she took a lot of air and maybe she felt cold. So, now she started again to develop. I make a prediction that her buds will be really fat. She is very healthy and responses absolute perfect to the nutrient schedule.
One of my favourites, quality smoke and genetics of this strain...also have two going on week 1 in flowering, had a few bagseeds from previous grow.. hope all goes well for you mate
