yellowing of all new growth, zinc def?

Hey man what's going on. My garden has been giving me headaches all year with that same pale yellow unhealthy new growth and it's been getting worse and worse. It effects everything, yield, trichome production, pistils, taste, the whole nine yards. After misdiagnosing all summer I think I have it figured out. It's a Boron deficiency caused by the ph of the water and food solutions being too high. Boron is not absorbed when ph levels are above 7. I thought I had been in the high 6's with my levels but in actuallity has been low to mid 7's for a long time now.

Just realized all of this today and made adjustments accordingly, keeping my fingers crossed.

My 2 cents brother, good luck!

if i had to guess..I would said slight nute burn..and the old more mature leaves could handle it as the new growth could not..hence the light yellowin and squeezing of leaves.if it was MY plant..a good flush and nothing but water for the next week..IMO. then look at the new growth again and make your decision as to "up" the nutes or not

Do you realize you just said its burned because of the lighter new growth. If new growth couldn't take it then leaves would be dark green or fried.
