Ya only reason you back down is if their burnt!Look good.
"i am going to wait a little longer between dips and see if they perk up" B careful
O.k. your nutes are added 2 ur water,absorbed into the cube.The roots uptake water/nutes as needed.As the water evaporates the nute consentration is greater(mix up some nutes,375, and put in a cup,place said cup by a window.Come back in 24 hours,the ppm is gonna b alot higher).
The cube DOES NOT need to be completely submerged inorder to uptake water/nute solution.Dip your pot so bout 1/4 of cube is in water.Trust me here.This will eliminate the "droopyness" of the leaves.
Now your lil seedlings,give em a gental squeeze b4 replacing under the light.You dont want the cubes drentched so to speak.
Do you have more 4" cubes?Put em in.You don't want the inital TAP ROOT to air prune(once it hits direct air it basicly stops vertical growth.This is fine later in life,now the root is essential).Just dont put into pots,yet.
Remember 200 ppm 5.6 ph 4 the water 4 the cubes!Don't leave the cube soakin 4 2 long(I drop into bucket,let sink,wait 4 air bubbles to do their thing,give it a squeeze while submerged,let it refill,then remove and squeeze out the excess.
