Dark Phoenix Photoperiod 2nd Grow

The plants have shown some good growth this week and have responded well to their first feeding. I fed the plants grow powder from Green House Feeding mixed with water pH'd to 6. The plants have been suffering from heat stress as I haven't yet purchased an exhaust fan and carbon filter for the grow, the two smaller fans that I purchased just simply aren't powerful enough to circulate airflow within the tent. Another problem has been the lights that I have been using are not dimmable and thus will be at max power for the whole grow, so I have had to raise the lights as high as they would go in my tent as the plants started to bend to avoid the light. I will probably start low stress training next week or at the start of week 3 depending on how the plants develop.
