Healthy Looking Leaves Fall Off With Barely Touch

What up people? I'm currently on day 21 of flower with an LSD and a Blue Mystic. Both have been topped and are looking killa IMO! I have noticed over the past week that I am finding more and more healthy looking leaves that have fallen off. Seems to be mostly from the Blue Mystic. She even has leaves that fall off at the bottom of the plant when I barely touch them. I mean barely touch! The leaves are not dead and necrotic either. They look healthy to me and are all different size. Anyone have a diagnosis for this? I would appreciate any help I can get! Definite +rep for your time and help! Here's a few pics of them:



LSD:

Blue Mystic:

I feed them ro water. 7L mixed with 2tsp. Epsom salt, 3.5ml of rhizotonic, 17.5ml of cannazyme, 17.5 ml each of coco a&b. I also use atami Bloombastic every other feeding so far at 2ml. I haven't noticed any nute burn. I use the canna calculator every time. The ec is around 2.3 with the bloombastic. The last feeding w/o the bloombastic the ec was at 1.93. I am in pots so it's drain to waste and the mix is always ph'd to 5.8.

Insufficient light, the plant is dropping them because it can't sustain them.

Really! Cool! I can see the that. She is a beast and I can see where that could be the cause. Thanks Punk!

Anytime bro.

Ya its kinda like the plant is giving its self its own lolipop treatment.

I thought I was overwatering my Blue Mystic, so I ignored it for a day, when I checked it I thought it had died. Leaves dropping lke crazy, plant looked like it had had enough. I watered it and it snapped back, minus a bunch of leaves. I guess the moral of that story is BMystics like to drink, and don't want to go thirsty, even for a little while.

I was trying to make sure it dried sufficiently between waterings, but damn, this surprised me.

^I've had a similar situation, recently, and also had healthy leaves drop off. I attribute it to letting them get dry to the point of drooping, and not from low light levels, even though the were lower leaves. I've never had it happen in veg,(yet) but has happened several times, during flowering.

hehe, ya they can drop from lack of water, but if it was over watering, your leaves would be curling in from top to bottom.
