Just a quickie.

I'm way south of "pro", but do have an observation or two
You have them in hydrotron, and you water them once a day, you say?

That will not do.
You are treating the 'tron like soil, brah.

'tron is a hydro medium and does not have the water holding capacity of soil or coco.
It wants ebb n flow, or drip.

And with a humidity of 50%, spraying the leaves is not necessary and distilled water can leach salts from them by osmotic pressure.
It's simply too pure.

Even rainwater has soot n spores n gasses, n dust in it.
Storm rain has a good amount of fixed nitrogen too, I think.

So, my opinion, stop spritzing and distilled water and wet the 'tron much more often.

Prolly don't want the bloom nutes 'til ya go 12/12 either, yah?

Might want to read up on hydro while you wait for them to recover.
Check the first link in my sig.
Aloha,
And grow-on!

Temp. stay at 65f.-70f. during on hours, and 60f. during off hours. Humidity stays around 50%. I use distilled water to mist them(foliage).
