I got 6 OG kush (Reserva Privada) and 6 Ak47 (Serious Seeds) going. This is my 3rd grow. Started them from seed 25 days ago. The AKs are looking okay but some issues with the kush. I know the humidity in the room has been too low, i havent been able to find a replacement humidifier filter since its the off season at home depots and lowes, they arent in stock. im flowering 24/7 under two 600w MH, temps range from 74-80 and humidity is about 40. They are in 3gal buckets, fox farm oceans forest soil. Im using all fox farms nutes too...waited till they were 21 days old before nuting for the first time...and only went half strength. I know oceans forest soil is kinda hot. I see some leaves curling up... too low humidity? the soil isnt drying out, its watered good.... and some spots brown spots on leaves? ph problem? or deficiency? One of the kush plants looks to be growing weird, like its mutated or something... never seen it split in that weird way, i hope you can see from the pics. any suggestions? feedback, much appreciated.
