Runtz(Zamnesia) in scrog under cobheaven

Week number 7 of the Runtz in their 12/12 cycle and 5 weeks of flowering have past. The buds are fattening up but more leafs are getting less green. Could be nitrogen deficiency or maybe the ph levels were to high. But it's most visible on the left side of the tent and all the plants are getting the same amount of nutrients. I'm hoping it will not go to fast as i'm still 3 – 4 weeks away from harvest. 😐 On the good side I don't see any budrot or mildew and the fungus gnats are pretty much under control. There were'nt many in the first place. The Runtz were fed twice this week (ec 2,09 – ph 6,35) 3 days were dry and I've given them ph adjusted tapwater (ec 0,5 – ph 6,35) also twice. EC levels will be lowered next week as I see some leaftips are burned. And pk 13/14 was also given for the last time this round. Temperatures stayed between 18,9 – 25,1 °C (66 – 77°F) and humidity levels between 39 – 57 % The Airfan is working at 100% most of the time and when it gets too hot I open the right ventilation flap of the Mars Hydro tent. The one on the back is open 24/7, the right one I close when the lights go off. The left one is closed all the time. The grow lights were lowered for the last time. They're now at a distance of 48cm (19 inch) from the plants and are shining with 324 watt power. This will be the highest power for this grow. Thats about what happened this week. Enjoy your flowers and see you within seven days!✋ Do you want to grow this strain? 👉 https://www.zamnesia.com/6000-zamnesia-seeds-runtz-feminized.html 👈
