Weird coloring on this plant in the middle.... What say you, IC?

[PHRosin]

Genetics: Big Bad Wolf 2.0 (feminized) (Chem '91 x Chem D)- CSI Humboldt

Tent: 2' x 4'

Light: Spider Farmer SF 2000

Nutrients: Gaia Green All Purpose 4-4-4

Water: soft tap water with silica, hydroguard, and cal mag added to it, then ph'ed to 6-6.5. Add recharge every 2 weeks or so.

Medium: Pro-Mix HP, Earthworm castings, dolomite lime, insect frass, dynomyco when transplanting.

I transplanted to 1 gal pots on July 21st and these pics were taken on August 8th after they were topped. The one in the middle looks sickly and weird. I think I also have some tip burn and general slow growth. I plan to transplant into 5 gal pots, move them into the 4' x 4' and flip to flower by next weekend. Any advice or tips and tricks are welcomed. Thanks!

It may be due to a couple of possibilities. It looks like the start of nutrient burn. If you can do a pour thru and catch some runoff and test it you may find the EC is creeping higher. Using too much slow-release 4-4-4 can come back and bite you on the ass.

Also, soft water mixed with cal mag water can buffer the nutrients causing a lockout. Its only guesses without a soil and water test. Keep us posted friend. I'm going to ride with you so keep us posted if you have any big changes.

I think it is just variegation known to be found in the Chems and probably due to too much inbreeding down the line. And in that case nothing wrong, keep on truckin'.
