First Grow Dutch Passion LED DWC

I had the initial mistake of overwatering the jiffy pellet before the seeds germinate which caused #2 and #3 to stunt. But both plants are now making its come back and back to growing bigger. 2nd true leaves has started to show on both #2 & #3. All I did to fix the issue was to let the pellets dry for 2 days and waited for more roots to develop. #1 seems to not care at all about the overwatering and just going about her business and growing. I had just germinated 2 more seeds in hope to replace #2 & #3 but since they're making a comeback I will just continue growing #4 & #5 along with the rest of the girls. I am adding a small amount of nutrient of Growth Technology Formulex at 1ml/l to #1, #2 and #3 this week. But, I am going to wait for 4 more days before i actually add Formulex. This is because the Cal Mag I have fed them earlier contains all the necessary nutes they need for now. I am going to also add some microbial innoculant at the same time namely bacillus a. and some Effective Microorganism Innoculant, EM1 to protect the roots at this early stage. The reason why I wanna do this early is because of the climate I am in, and the temperature here can reach around 36C. At certain point even with AC on, I will still get a temp of max 31 in the tent. To counter this, I misted the tent every 6-8 hours(which seems to bring down the temp) and occasionally airing out the tent. With AC on full blast the temp will range around 26 to 27. I couldnt have imagine trying to grow with HPS/HID as they emit a large amount of heat and that in turn will lead me to needing to cool the room much more.
