Leaves showing a problem help :(

[TRED]



I'm am a complete newbie with some basic knowledge.

Strain auto ultimate by Dutch passion

The problem my babies are 13 days old and the leaves have some spots of what looks like rust and the leaves are twisting and instead of the spikes they are more rounded.

Not sure if this is a deficiency of calcium, magnesium or phosphate

Setup
120 x120 x 200 mylar lined tent
200 watt led reflector and 40 watt exo terra 5.0 30" T5
Temperature 20 Celsius
Humidity 50%
Light cycle 20 on 4 off

Water ph ed after adding supplements to 6.5
Soil ph is 6.5

Supplements
Dutch pro multi total. 0.5ml per L
Bio canna Vega 0.25ml per litre
(YESTERDAY) call mag 0.5ml per litre
Because I thought it might be mag or calcium causing the problem but it hasn't got any better in over 24 hrs

Im probably way off the mark but something similar happened me, spashed water on the leaves and lights burnt the spots..

 

[TRED]

That is a possibility but doesn't explain the deformation and twisting but thankyou

Those spots look like nutes burn from splashes to me. I can't comment on the twisting although I have seenot this trait in some strains that grow out just fine

If we could get pics in natural lighting, and some whole plant pic also, it would help with diagnosis.

I have taken them into a better light the top pic just seems to be wilted :/ but on the up side I must be doing something right as I have a few good ones

Looks like a happy well developed Little Seedling I think she's doing just fine.

That was a pic of the good one have changed it now

I see everything looks different now. You have a slight Calcium deficiency going on I wouldn't water any Cal Mag into your soil I'd go ahead and prepare a foliar spray. A couple drops of the wetting agent like soft liquid dish soap or something like sm-90. And then one or two mil per gallon of whatever Cal Mag you have.

Spray top and bottoms of the leaves with lights up higher. Having a deficiency this early with LEDs may meen your light is to low.

Thankyou so I make a mix of soapy water with a dose of calmag spray leaves top and bottom do I wipe it off with some paper towel?

And raise the light a few inches and it should sort itself out?

Thankyou for your advice
