need help, something wrong with young plant

[lilsativa]

I'm growing in soil, leds and no nutes yet.
when big fan leaves started to yellow between veins I decided to wait some time to see if plant will heal itself.
Today I noticed that situation has gone worst , new grow has some brown spots.

please see attached images and advice, what's wrong and how can I help my plant.

looks like a disease to me.. i would get some trace minerals added as well, some food, and better soil haha what soil are you using

 

[lilsativa]

how to check if its disease or not?
if not disease, will replant fix the problem?

 

[andy s]

i wouldnt replant it i would just try and correct whats wrong before that. get like some cheap jacks 20 20 20 it has all the trace minerals in it youll have to do like 5ml per gallon then slowly go up to 10 and 15 you shouldnt have to go higher than that. itll correct the issues if its a deficiency. what kind of soil are you using? good drainage in the soil and pot?

andy , soil is from flower shop and it does have good drainage, but not sure what elements in there and why plant has some deficiency. So I did how you told, added npk 5-5-5 and it also has some other nuts in it.
how fast should plant react on new available nutes? I mean do I need to wait week or more?

Looks like a calcium and magnesium deficiency. Let it dry out a little ,looks a little overwatered

at least 3 to 5 days before you see changes a week to really notice

 

[andy s]

do you have calmag? it does need calcium as well i didnt know what all you have for your line up did the 5 5 5 have any in it? what other nutes does it have in there

K lock out from too much Ca or N?

 

[shrxhky420]

Mag deficiency, add dolomite
SH420

he hasnt fed them yet (besides the feeding he just gave them) so its highly unlikely theyre over fed ca or n

Mag deficiency, add dolomite
SH420

dolomite lime takes a good amount of time bc little is water soluable. it also messes with the ph of your soil.

WHen he said the soil was from the “flower shop” I guess I assumed it was loaded with nutrients already.

it could be but theyve been in it for a minute i assumed lol i could be wrong

 

[andy s]

i know it does need calcium though as well i assumed he had tht or there was enough in the medium since theyre early on lets hope the 5 5 5 does if not

thanks for suggestions guys.
as I've added npk 5-5-5 with very low content of cal-mag on nov 30, I think to wait 5-6 days to see if something good happens
if not, maybe there is some faster solution (foliar feed) for this case? when I had problem with my first grow(this one is 2nd) RIU member suggested to spray epsom salt and it did actually help.

Epsom salts also can be very very bad for your plant so be careful using it

Looks like cal mag def to me. I got those spots before and upping my dose of cal mag fixed it over the course of a week or two

Care to elaborate on that?

 

[andy s]

Care to elaborate on that?

it can build up in your growing medium and hurt your plants or kill them. its not meant for all the time use. which is why i said use it carefully

 

[andy s]

Care to elaborate on that?

lso check out some people who have used it specifically on pot, some had bad outcomes
