Is it time to transplant?

I agree with Harbringer, that’s a fantastic way to judge how often you need to water. I use that on my own plants and now just water when the plant “looks” a bit thirsty to me. I would open your tent up instead of leaving it closed if you can’t get the temp down... you said you may have overwatered but that was already answered. Your light is also flickering... I’m not sure if it’s that or your camera but typically camera’s see flickering that eyes cannot see. I would recommend looking at lighting that maybe isn’t so hot if that’s an option... if not an in-line fan is a definite need.

Unfortunately Noidz we start with simple parameters and work our way up... Your temps being too high is gonna cause all sorts of transportation problems. As too if a plant is ready to transplant a good trick for dirt growers is too try to gauge how fast the medium is absorbing the water you are adding. if your plant is taking in the water almost as fast your putting it in(ie watering every day or two) Your plants could use a bigger container. Also constantly lift those containers see how they feel. They will feel heavier with water and lighter when the medium starts to dry out.

Thanks :) I will wait for them to develope more. I am using ph meter, i have to calibrate it to see if its actually alright. Using tap water, started giving biobizz biogrow 3/4 days ago. I try to water less, letting soil dry, because i think i0ve had problems with overwater in the past. I also have to say, my tent is really dry and hot. Yesterday i could bring down the temperature to 30ºC, but before that it was always really hot.
