Black Dog LED Phytomax 2 400 Kit Grow #2

Some of the leaves are all getting orange/yellowish on the perimeter of the leaves. Day 99 I fed with 4 Gallons of Nute Water over the 4 Plants. I took advice of Black Dog LED Guru's and upped the nutes to 33% of Remo Recommended nutes. Day 100 Blue Dream #1 Plant started the Orange/Yellowish on some of the leaves. Bud Production is doing good! Day 102 all 4 of the Girls started to get Orange/Yellowing - Again for the most part on the perimeter of the leaves only Day 103 I RO Watered with 6 Gallons over the 4 girls. Measured the runoff with nothing standing out
