2nd grow with updated grow room

Temperature and humidity are rising fast because of the high temperature outside which cause the top bud of my GC#2 to rot in the end of the week so I snapped the contaminated parts. I took a look at the tricomes and SB#2 is the closest to harvest with 30-50% cloudy tricomes (buds are very frosty). She has really bigger, denser and more resinous buds than the others and by far so I'm eager to taste it. SB#1 & GC#1 tricomes are only starting to turn cloudy and GC#2 ones are latest to mature (not surprised since she took a lot of punches these past few weeks). Watering for this week: 09/05: 5L to GC#1 at 6,6pH,5L to GC#2 at 6,6pH, 4,5L to SB#1 at 6,7pH 10/05: 4,5L to SB#2 at 6,7pH 12/05: 4L to GC#1 at 6,5pH, 3,5L to GC#2 at 6,5pH 13/05: 4L to SB#1 at 6,7pH, 4,5L to SB#2 at 6,7pH
