Nute Burn?

[DieselX]

Hi there hopefully someone can help. Is this nute Burn or a deficiency within the plant?

I am using soil (John Innes multi compost) with a 40% perlite mix.
Nutes were baby bio but now switched to A&B sensi Bloom. 4ml per litre each plant gets 0.5 litres.
Plants are 5 weeks young autos now starting to enter into flower phase.
pH is 6.5 that's checking the soil not the run off.
Temp is approx 27-29 degrees
I water+feed every 3 days
Lighting is now 600w hps was led and T5's.
Grow tent 4x4x7 feet

All other plants are looking fine so far (5/8) just 3 that have this on their leafs.

Thank you for your time reading.

it almost looks like you spilt some drops on the plant while the light was on.. But to be sure on the next watering I would drop the nutes down as I don't know how hot John Innes Multi compost is... But if there are nutes in the soil then just go with water on the next round and let the nutes work out of the soil... Then go back to normal...

Thanks @k0ncept i did think roughly the same thought with the area in the middle of the leaf. Possibly the humidifier onto a top leaf and dripped down on the other?

Do you think she will be ok for a couple days untill then or should i act now and flush her out?

Thanks in advance
