Water type: mineral water
pH level of water: adjusted to 6.0
PPM of water: 50-60
Growing medium: pure soil, no perlite mix
Lighting: 120 watt LED, 240 watt CFL
Lighting Time: 24 Hours
Average Temperature: 24.5-26.0 C (76-79 F)
Average Humidity: 55-65
Stage: Vegetation Period
So about a week ago, I gave the plant a dosage of 3-5-5 condensed nutrient solution because the potassium level was low (the stems were turning purple/brown, researched from the net) and im not sure if that had anything to do with it.
If its calcium deficiency, what do I need to use to regain the required minerals? I'm living in Asia now so a lot of the name brands (fox farm, Jacks) are not available. Please guide me! thanks a bunch!

i use calmag from botonicare but im not sure abt in asia.. you can use crushed up egg shells for calcium if you cant find anything else.. also if your in soil bump your ph up to 6.3-6.5

So how do I apply the crushed up egg shells? Do i have to soak it in water or put on the dirt? does it have to be boiled? thanks!i use calmag from botonicare but im not sure abt in asia.. you can use crushed up egg shells for calcium if you cant find anything else.. also if your in soil bump your ph up to 6.3-6.5

chrush really well and mix in top layer of soil, then water as normal.. i wasnt thinking about it but if you can find bone meal it contains calcium and should be pretty easy to get

Great advice! Thanks a lot! First thing tomorrow morning if the world hasn't ended, i'll use up my breakfast egg shells! BTW, do I need to wash out the egg shells after I break them or the egg white good calcium nutrients?
Much appreciated!

it probably would be best to wash the shells to avoid attracting pest, and i wouldnt worry to much about the world ending anytime soon

Ok, so the world didn't end and my plant isn't getting any better for some reason. I used 2 egg shells and grinded and mixed into the soil, as well, i added some tomato nutrient pellets that has a dosage of calcium into the mix, watered down twice the past 3 days, but the leaves are still brown spotted and appears to be even worse than before, any ideas?

before you worry about eating a bunch of eggs, and either crushing them and waiting for them to water in, or boiling them, and using the water, I would recommend getting your PH in check.......
You may have enough calcium and mag in there already, but just locked out from the PH.View attachment 2453413
Sorry, just noticed in the last post you said you already put the eggshells.
It takes a while for them to dissolve and water in, you won't see it for a couple weeks or more even looking like they're disappearing. (I tried it last season).
Once you get your problem fixed, the damaged leaves will not 'heal', but should not progress, and new or additional growth should not show damage.
Personally, I would not try feeding or anything until you are convinced that your soil PH, not just your water PH is in a good range, meaning 6.5

So does that mean i should up the pH level to about 6.7? Thanks for the chart!

Also, next time you move the plant to a new home, I would recommend some (about 35-40%) perlite added.
It really made a difference for me over straight soil.

looks like minor nute burn to me. ph 6 isn't that bad.. the range is 6.1 -6.8 ..i can't see you getting complete lockout at .1 of a ph. plus your run off will not be a 100% correct reading in soil...my 2c
heres a pic of nute burn..looks similar to yours ,but worse ..thats why i say minor nute burn.

If you're only able to check your water, not the soil, I would, yes, for two waterings maybe three, then go back to 6.5

Sorry, that was my fault, just skimming quick the replies, didn't notice that yes, the one guy helping DID mention PH, but I edited once I caught my mistake.

He's a full half a point below where CA and MG stop being able to be utilized by the plant, and he's trying to throw more at it.
When he finally gets his PH right, the plant is not going to know what to do with it all unless it's been flushed out by then.

You mentioned watering twice in past 3 days, if I were you, I would hold off on the watering for a few days.
Especially with no Perlite in there, I can just see you drowning your poor plant that you're trying to save.
Also, once you DO start feeding, don't forget nutes usually bring PH down a shade, so best to check after adding nutes to the water.
