plants are little stressed because of super high temperature, i'm using very intensive airflow to reduce this stress, but can't go less than 31-30c. next week would be harvest week for this girls, trichomes are mostly white it feels like they are almost ready.. i'm watering plants every second day, they drinking 1.5 L each, last 10 days(5 waterings) i'm using ph-balanced water only. last week is also temperature extra high outside and leafs are little burnt, but should not be a problem i hope..
