I'm beginning week 3 of flower and they were all the same height before, but now one plant has stretched an extra 10" or so. I have a p600 light, and I pulled the left side higher than the right to offset the uneven canopy. Is this ok? Any other tips?
well several things could be a factor
1 the strain itself (if it was seed it is possible it took after the other parent of that strain)
2 the feed (not sure what u are using but everything has variables from soil mixture to settling of the feed)
2a is that the plant u feed the bottom of the water jugs/tank.
2b are u feeding that plant first with a fresh mix of feed (still stirring around no settling)
stretching during flowering happens some times 2/3 the total plants size when it was in veggie stage right before u flipped it
if u are really worried about it
1 move the biggest plant to the center as she is going to offer the best buds so should get primo light
2 move the 2 shorter ones to the side and set them on something to raise the lvl to where u want (if they stretch u can remove it whatever u used )
canopy is not a big thing when u are not SCRoGed plus u are in a tent so u are getting light refracted off the tent walls given u better area of coverage and depth (compared to open space)
double checking the light u are talking is this one

if this is true then u are a 5x2 footprint with 90 degree lens (your good on depth of use able light ) ......just keep on the feed water (next round u do will do better just increase the feed and water learn the strain and u will max out with in 3 grows of it )
