I start my seeds off in a small 1 gallon or smaller using the green house method, and then let them grow up for a week or two then put them in some 3 gallons... then if they out grow that I move them in to something bigger
I have used a reverse osmosis and I have used fresh from the city water, didnt see a difference until i pulled my girls out the pot.. seems like less to clean out of each pot and not as much scale and salt build up in the pots..
why not, there is a lot of talk about flowering with T5's.. I have used both for flowering and I was shocked on how good the T5's did,, but then again it looks like your not using the HO T5's.. just my .02..
whats your humidity at? and your temps, its hard to help someone out that doesn't give the conditions ya know.. They don't look that bad though.. Very good strain you are going to like it a lot.
I like to use both shades, 6500 and the 2700 I think it is.. It helps, I noticed that vegging under T-5's, I get way more top's and they stay shorter, I like to slam the light right on top of the baby's
