Stressed plant; Light or Nutrient ?

[hightech316]

Droopy leafs, Some Discoloration. Main concern, Leafs are shrinking ....

2x2 tent. Medigrow Sun v2 325w . 70% humidity . 78f . 5 week of veg. Inside 3gal is ,

Peyote zkittlez

90% Pro-Mix HP
10% Worm Castings
Gaia 4-4-4 .
Alfalfa meal
fish bone meal
gypsum
kelp
( All at recommended low dose )

First few weeks of her life, I had the light too close . 18" . I immediatly figured it was light stress and made necessary changes. She bounced back Now light is at 34"

Took a turn for the worst when watered or so I thought it was the over water (28oz water ). She never bounced back. It's been about 7 days .

I did top feed her Gaia multi purpose 4-4-4 , Two days prior to her change .
Link to Grow Diary - I have more pics there .

Thanks for any input!

Do a good dry back. Cal mag if you havent. Also lower the light if you can (prob just a few days) Just to let her adjust.
Whats the ph level at on run off and the water you use?

I've given her cal mag a few times.
The light is at lowest setting, 40% .

Came across a few cool sites that help you calculate and adjust lights .

https://growlightmeter.com/calculator/. --- Calculates daily light integral (DLI)

*** I left a piece of info out. Two days before she took a " dive " , I broke her main stem. Near the top of the stem, only 3 nodes were taken ( had 9 total nodes ) . So I went ahead and made a clean cut to " Top " the plant . Been 5 days, not healed completely yet

I haven't seen topping stress this hard . But I did begin LST at week 4 prior to topping .

Perhaps a perfect storm of all types of stress?

I've heard that the leafs shrink and bend when too much there is too much light. So perhaps that is the main issue. Maybe I can get a controller and get the light down to 20% or less.

Your output setting it perfect.
Just raise your light, its the beginnings of just a mag def.
Id use salts and raise that light to 26in above canopy.

Thanks. How often and how much would you suggest?

2-5 grams a gallon
And at your normal feed rate.
The discoloration may get a little worse before its stops completely.
Affected leaves may gain some green pigment back. But the bulk of the changes from the def will stay. Just monitor all new growth to ensure either,
Your light is dialed, may still need to raise some more since your light has presets for output.
Or that you have the salts dialed in,
