i use fox farm big grow and tiger bloom for flowering. thay have just completed the first week of flowering and the plants have been showing these signs for about 5 days. I will be giving them the first dose of flowering nutes next watering I use cfl's and and 200 w hps but ordered just a 600 for these plants and they should be here this week. I think they are getting plenty of light, the leaves are really thin and wrinkly which makes me think it is too hot. the humidity must play a part in there somewhere but I don't know if it's too much or too little....lights on it is 60% during night it is about 50-55% anyone else help? they are still looking bad. coloring is coming back a bit... could this be light shock from the change in light regime for flowering??
