Hey everyone very new to this ! Only reason I'm on here is cause in currently having an issue with my babies ! I'm currently growing 20 plants in 7g smart pots with a soilless mix ! They are under 4 1000 watt air cooled lights ! Flipped 2 days ago ! I have lots of good air in and out and plenty of fans circulating the air . I ph my water to 6 and same when I feed ! I checked my run off a week ago before transplanting and it was at 6.1 ! my new growth is getting very skinny small leaves and turning very like green in the centre of the leaf ! While the rest of the plant looks perfect ! just very new growth affected ! Problem had gotten worse since flipping my lights and I transplanted 2 days prior to flipping ! Plants did very we'll after the transplant no shock what so ever ! I will post a few pictures I really hope somebody can help me !
