Hello people I am just looking for some inputs, I am 7 weeks into flower and all the top leaves on my plants are turning yellow, I read it could be light burn but the closest plant is 18" away. I am using a 600w hps in a 4x4x7 tent with a 4" extraction and now I have a 4"intake fan what I set up yesterday to help with heat problems. I have one big oscilating fan blowing against the walls of the tent because it seems too powerful facing the plants and two 7" fans on the floor. The temperature has been between 25c-32c for the past week and humidity is usually between 55%-75% I know its high but I am hoping my new intake fan might help.
I am currently feeding once a day with canna a&b 1ml per litre untill around 40% runoff. I kepp my ph between 5.5 and 6.5 using drops now my meter is broke. The plant in the pics is the most yellowing one so I just took pics of that but there's 8 more in there and they are all like this.
Any inputs would be appreciated.
