In picture 3 above the new growth on the main cola sites is curled up and contorted. pH is a tiny bit high, TDs run off is around the 400-600 mark over the week. Humidity has been intense for weeks in the high 70s to mid 80s, I'm only watering to feed once a week. Help!

Hi there! This looks like a Boron deficiency. This is not a common thing! This may come from : 1) Incorrect pH and/or pH fluctuations. 2) Poor nutrients intakes. Are you watering with reverse osmosis? 3) Too much humidity resulting in a lockout, roots can't absorb Boron anymore. As for a solution to help her recover, you can mix a teaspoon of boric acid in 4 liters of water, and see how it goes. I'll be around, keep us up-to-date, and happy growing!

I've had that happen to me due over feeding. Give it a light flush and stop feeding for a while until you see healthy new growth. 4 ml/lt of fishmix is a lot, when you resume feeding dial ir back to 2ml/lt. That high feed is probably causing lockout of some minor element.
