The first batch that I killed I feed them super thrive they were about a week old and I think that that might of burned the roots, since then I will not fertilize them untill 2 to 3 weeks old and what I have been reading 3 to 4 weeks is the best time to feed them I only feed them spring bottle water so far. The fan is not directly on the plants it is olny to keep the air circulating and to keep the temp down because my grow room is so small width is 8 inches length is 4 feet and the height is 6 feet. And the temp is normaly high 80's or low 90's so could it have something to do with the temp being so hot. The brand of soil that I am useing is mirical grow moisture control and I went through all of the soil and picked out all of those damn nut's so it does not have any slow releasing fertilizer it is the about the only good soil that I could find for growing. Sorry I could not get any pics my camera on my phone is not working so I will go down to the store and try and get a new phone so I can post some pics.Thx guys.
