This problem didn't start raising it's head till flower. Now in my third week and the leafs on 2 of my plants are bright yellow with little to no green. 3rd plant is beginning to show signs and last plant is doing great but i can see faint hints of onset. These are WW and seeds are around 4 years old but were sealed. I thought my nutes might be old so bought new Flora nova grow. Have tried running nutes up high around 1200 ppm to see if the added zinc in the nutes would help but did not. Temps in the room around mid 70's and ph has been low around 5.0. So I added ph up and am running PH at 6.0. Have been flushing reg. every week and add fresh water. So this is my call for help hope someone has experience in how to add zinc to a hydro drip system. Will be glad to answer any question. I wish I could post a pic but my camera is not working well enough.
