Nute Burn? with pics

[Illadelph]

is this nute burn, the first two pics are a few days after first feeding (1 tbs/gal floranova veg, thats a half serving) The second pics are after the subsequent watering about a week or so later. (seemed to have burned more from the watering from the high level of nutes still in the soil?)

Is it nute burn as i suspect?

how can i fix it?

any other advice, input, comments?

not a burn but a total lack of magnesium and calcium get a sensical or calmag suppliment!!

 

[Illadelph]

what makes you say that? not that i'm arguing, just trying to learn

why does it get worse after watering?

also, my nutes have cal. and mag. in them

Burn is usually accompanied by the leaves curling upward at the tips. The burn looks rather uniform (one color)...not patchy as in the pictures above. Simply BURNED and CRISP like a dead leaf. Yours are colored and spotted, the brownish-yellow coloration is also a dead giveaway about the deficiency.
As far as it getting worse after watering: I can make a blanket statement....plants need water, light, nutrients and air to photosynthesize. When you add water, and some nutrients...the plant is going to begin that process....if it doesn't have enough of what it needs, it will "reclaim" it from other parts of the plant (ie-your bottom leaves). The addition of water and nutrients is catalyzing everything to move into high gear....only it doesn't have everything it needs and the plants resultingly look sicker. They are TRYING to grow, but without the right stuff....
One other thing: burn kind of uniformly burns EVERYTHING.....it's something you'll see from the top down. Deficiencies generally start from the bottom UP.

What did you give your plants, & did it take care of your problem. I have 2 g13-diesel that have those leaves.

more info ...fill in the infirmary questions...but foremost, get the exact ph of the medium

 

[MynameStitch]

I agree with core, but I will have to say this plant does look like it's burned to a crisp; the poor plant's nutrient level is bonkers, I see all kinds of issues with all kinds of micronute problems.

A flush sounds like it has to be done... but fill out these questions as much as possible.
