Reave's Soilless: Peat, Bark, Sphagnum, Perlite, White Widow 2018

5.5 is even low for coco, which yours isn't whatever it is. pH at 6.0 and see how they do. Also there should be a fan on them directly. They should be vibrating and dancing with every oscillation.
 
Plants that needed water this morning got water with 1ml cal mag per litre and ph'd to 6.0. Guess we will see how it goes.

Don't have a picture right now but 1 or 2 of the plants had a tiny hole in the new growth.

On the plant where it was thought magnesium was an issue the one leaf has progressed to having some dark brown patches. I will take a pic when I get home. The leaf that is the worst is a bottom leaf.
 
We can wait!

Attached is the one I posted earlier so you can see how the deficiency is progressing. You can see how it starts of with a whitish film.

If nothing is eating them (check the undersides with a loupe) then I'd stick with the cal-mag and the 6.0 pH and see if it continues. It can take a few days at least for that to correct after changing the pH and nutes.

Will do. I doubt I have bugs of any type around here. Way to cold. I will double check for stuff under the leaf. They kinda came out that way though from where they sprout.
 
can you get us a super high resolution picture zoomed in on those little white spots on the leaves? I am suspecting spider mites. Have you brought in any clones lately?
 
Flip that over!
 
Neem oil is your friend! I mix mine 4 tbs to a gallon and test spray one leaf to see how the plant responds. If it seems okay, spray just before lights out every three days for two weeks, tops and bottoms. Kills bugs dead!
 
Where there are holes, there are almost always bugs.
 
White spots on leaves are usually either thrips or mites. Thrips are more easily seen but some mites are practically microscopic.
