Hi guys, Im new to the forum and I need some professional opinions about my plants. Im on the 4th week of flowering and using an indoor setup with eight 18lt pots (5gals) filled with Biobizz AllMix soil . Im using 600w hps bulb. I feed them with advanced nutrients grow,micro,bloom pack. The temperature of my grow tent is usually about 80f with %60-70 humidity. I have a powerfull ventilation system and 3 usb fans.
The soil of the plants takes too long to dry. I usually water them every 6 or 7 days. I use total of 36ml of nutrients for each pot. (12ml of grow,micro and bloom). I contacted the advanced nutrients support and they told me that I can use their hydrophonic nutrients with soil. The problem is that the leaves of my plants are yellowing rapidly and I don`t understand if it is caused by a deficiency or over feeding. Budding has slowed down and dry leaves started to get crunchy.
I really dont know how to save them. I need some helpful advice in order to bring my babies back to life
Here are some photos of my grow room,
