3 Strains-Custom led-Floraflex-Cococoir

3 plants seem to be catching up from the late start they had. Cut off lowest set of nodes on each plant and then topped them all leaving 5 sets each on 3 plants The Dutch Passion Orange auto I found a seed from a previous grfow and she was born topped already. (see photos). I topped her two branches aswell Began to show calmag issues so upped the dose and added some epsom salt to the mix. Still watering daily and trying to hand water alternate days with bio root and big bloom as they don't sit well in the reservoir Pistills here and there so hopefully they start stretching before full flower comes along. Lights are at 20inches at 90watts. Seems low I know but they already stay pretty short at this setting. Any growers with bridgelux or Samsung led strip builds out there holllaaa. Cheers
