my little garden fastbuds

Hello Sergio, for me, I was always able to get the desired temperature just by finding a balance between the exhaust and circulation fan. My takes would be: - More powerful exhaust - Limit the circulation fan power (sometimes I had problems with too strong air circtulation inside of the tent, because it was also taking the heated air from the light back down to the plant) - Enrich the CO2 in the environment. With a proper light, watering and nutes, the CO2 enrichment can make the plant work better even with a bit higher temperatures. Wish you luck :)

Ola amigo tudo bem ? Todos nos ja tivemos problemas desses. Para baixar a temperatura podes comprar um extrator mais potente, e usar mais ventilação dentro do armário. Subir a luz para não ficar perto das plantas também pode ajudar. Boa sorte no cultivo e abraço

Add more fans to get more airflow. The expensive answer is put an air conditioner in your space. You can also add a cool mist humidifier that will bring temps down by a degree. But will introduce more humility so there’s that to consider.

She looks like she is stressed out. Serrated edges curling up, Usually this is a sign of heat/light stress but can also show with other signs of stress like over feeding. I believe you have a nutrient lockout from to many nutrients in the soil.. From the leaf tips burnt and curling down to the serrated edges curling up. If you have a PPM meter then checking your runoff to see forsure. I would stick to just water for now and see if she improves. Happy Growing

You dont have much info of the dosage of fertilizers or even what are you using. If you want to know if is a calcium def you need to check ppm of the water before you add fertilizers, buy a cheap tds ppm meter and check it 127ppm= 0.199 EC 250= 0,4 EC and then you add your fertilizers, use a calmag product to get to the values I mention. if you find that your water was low in salts feed them with 250ppm till you clean roots before you cut them.

looks to be a nice shade of green to me :) I think if anything its a very slight deficiency in cal mag maybe nitrogen too so on next watering when shes dry i would just up your grow feed abit and that should sort it out burnt tips often indicate and underfeed or an overfeed the orange spots on leaves tells me she needs more cal mag rather than to little :) Best of luck finishing the run :)
