Ok this might sounds crazy . I use to grow white widow and bluberrry with neon of 13 watt each x 4 and the vegetation went pefectly as wanted. Then i move so i didn't had the chance to see how the flowering is gonna do . This year i tried blue cheese - dutch dragon - big bang and i change the setup which is a 4oo watt hps . All of them went down i dont get it the temperature is varying between 19-24(max 25) the setup looks perfect too me but till it get to the 2 weeks the head of the plant just goes down like its going to die which died after . The plant looks healty but i just dont get it they are all dying is it the 4oo watts hps problem ? Because before i use 4 neon of 13 watt each which was perfect for the vegetation and all the plant went through it witout one drying . Im soo pissed right now i just lost 4oo $ of freaking dying seeds but i think the problem is the 4oo watts hps . Please give some advice here.
