Strange bright spot on 1 leaf (at least so far) - please help - picture

[someonelse1981]

Hi All, Its on biobizz nutes and soil (light mix) - up to this moment - 3 feedings - root juice + bioheaven + biogrow, plant is around 25 days old since germination under 125w cfl + some lst already as space is very limited. strain is supersonic cristal storm auto. I googled already a bit but didn't find any definite answer only that this could be some fungus or cal/mag deficiency ? not sure as usually pictures were showing something a lot different (usually a whole plan was affected - but maybe it's just a start).Anybody has any idea what could this be and how to heal the plan from the issue ?Any hints will be appreciated. Thanks in advance

Hey man. I think u accidently just spilled some water/nutrient on her... Could that be possible? Cos she looks healthy and happy. But u better wait for one expert to give u a hand.

Thanks for the suggestion ! It's possible, but I didn't noticed it, I will keep on monitoring her to see if something new shows up next days and will try to be more careful when watering. bless

hey bud- that's physical damage, caused by what looks like a water droplet lensing the light and burning the surface tissue,... it's only on the top, right? It is unusual, given it's only 125w,... was it really close? combined with heat, it could do this,... otherwise, water/ nute' solutions on the foliage isn't a problem, as foliar feeding/treating is very common,...when done away from strong light, and not at night/dark cycle (mold issues)! Watch it to see if it spreads,... that spot may go necrotic, but shouldn't advance beyond this point,...:thumbs:

What's the NPK on your BioBizz grow ?

hi guys, Thanks for the help, I'm not really sure if it's possible (lamp burn), I was rather thinking that the solution spilled and 'burned' the leaf - but I didn't use a strong solution and as you mentioned it shouldn't be the issue, the spot was getting brighter and brighter and currently it's pale yellow - almost white, but no new spots and she is looking healthy imo, pics attached, the biobizz grow is 4-3-6, but i also use fish mix now (in veg/pre flower) which is 5-3-4

I don't know what your light schedule is but I get exactly the same until I switch to 24/0 lights. Logically I can only assume the water drops are condensation caused by the change in temp when the lights go out.

That's a lovely, healthy looking plant, personally I solve the problem of the odd dodgy leaf by cutting them off near the stem.

Not a very pro solution but for one leaf I don't mind

That is very thick foliation there... When I get those types I'm always fighting what I call "leaf sweat". One leaf will lay on another, humidity will cause them to sweat when they are touching. Especially after feeding/watering. This can cause some burning with you light, no matter the wattage or type of light. Can't see the first pic bu second one I can... Really can't see any spots at all in that one but from what your describing... Sounds like condensation buildin up between leaves...

what is really annoying on the forum is the issue with pictures, not sure if only I have this issue, but I'm not able to see all pictures, randomly it shows picture, and at on other picture it says that I don't have permissions to view (and I was able to saw this one earlier so this is not any permission issue at all), indeed, the picture you are able to see it's the only one that doesn't contain the spot as it was just a general picture of the plant which I assumed looks healthy (beside this one issue up to this point), maybe it's just some random bug in the matrix ;-) thanks for all the answers, if there are more issues I'll post

That pic I can see your plant looks happy and healthy my friend...
