Hey you need to replant a little faster from the cups....to 1 gal then to 3 gal.

I know how you feel about the seeds....I bought 10 DJ short blue berry $30 a seed...sprouted 4....three tried to do it and died and only 1 made it....you have to add 30 days to your grow if growing from seed insted of clones...it just takes time...there is no magic nutrients in this stage....

Keep up the good work....do not worry about different ages of your plants...it's not a problem...as some grow a different rates anyway.
