We have been growing indoors for about two years now and keep experiencing what looks like heat stress. But every when they are being fed the same thing, same environment... it happens randomly. Now we are in week 3 flowering and we have buds but no hairs! I'm freaking! Temps are 71-78,humidity is around 78-81%. We are not feeding full bites, using 1000 w on a light track. They were so beautiful and green and healthy until this last week and a half. We are in soil, running General Hydro nutrients. I am trying to attach photos but it's throwing an error. I will keep trying. Plewse ask away and provide any help you can. We will begin Thrive Alive red in two days.
