Yellow discoloration again
I'm annoyed by having to post another question but oh well. Yesterday evening I increased the PAR from 370 to 400 in center. This morning the top fan leaves were pointing straight up and so I raised the lights a little. I later looked and saw discoloration. Light burn?

Old/Bottom leaves is dying off at the edge ?
So these are the oldest leaves my plant has, the rest is fine.The edges are dying off and i don't know why, can anyone help ? The Edges aren't really crispy/dry. Is it maybe too much wind ( Windburn ) ? The Plant is receiving a slight breeze and the leaves are all shaking a bit.

Spots/decolouration on leaves: 1 sideplant (that I grow next to my growlamp) is getting a few spots....
So, I have 3 plants: - 1 centerplant that gets most of the light & 2 sideplants (left and right) who also catch a lot of the light, but not as much as the centerplant: the sides arent getting direct light, more reflective light. ?? The left plant is showing a few defects. Anyone?

Plant seems to be dying, should I flush? And if so, any tips?
Yellowing & wilting, I suspect the problem is too much silica boost .5ml every other water, combined w/ hot soil (FFOC) & a few feedings, & maybe underwatering(?) as I never have runoff, watered a cup or so every ~48hrs, when soil had dried. LST, no wild temps/hum, great airflow.

Burn leaves? Yellow leaves? BIg problem? (AUTOFLOWERS)
I had a problem with a lack of magnesium in the larger plant and I applied a little with a sprayer directly on the leaves, I got confused, I sneezed once on the leaves of the smaller seedling. Can I do something to resolve it? I even thought the LED was too close and I raised it

General health
Advice please just on wether it's looking healthy. :) I've been too careful with watering and some leaves turned yellow. Feeding 1 litre every other day but maybe that's too little? Stopped with the Biobiz fish and switch to growbloom. Leaves at the top look droopy still?
