Hi. Grow tent is 80x80x178. Light is vipar spectra p600 on 100% working. Light 24/0. 40 cm distance from top. Nutrients are 1 ml per litter of bio bizz grow, since week 3, slowly rising to 1.5 ml to end of week. Since week 4 is 2ml per litter. Soil is canna terra professional. Humidity is between 45-60% in 24h, temperature from 23-28c in 24h. Constant fresh air coming from room as window is open. 170m secret jarden fan with coil filter. Fan inside of tent makes a little breeze from other side of tent through other girls who are fine. Other girls was having same nutrients. Yesterday all of them had 1ml per litter of bio bizz bloom and bio bizz top max as they seems going into preflowering stage and I though it might be a problem with phosphorus. So, yeah, problem one got 5 litter plastic pot. Other ones 7.5 litter grow bags. So Because of plastic pot I seen roots, nice and white, healthy looking for me. I’m considering to Chuck it out if it is going to infect other ones. But it doesn’t looks like infection for now…
