Help rust spots and black tips leaves dying

Is any able to help i currently in week 2 of flower in soil and just got on top of 1 problem and now these spots have appeared and getting worse

Im thinking its deficiency of something but want to make sure

Unless you provide more detail about environment, temps, rh, medium, feeding etc, than the best answer I can give you is yes, you have an issue.

Temp is 28 in light period with around 60 percent humidity.getting down to 20 at lights of with 40-50 percent humidty they are in soil have had probs most way through flushed 2 weeks ago and everythig seemed ok untill now they are under 2 600w hps in a 3meter bi 1.5m tent they have had 2 light feeds of nutea since flush the ppm is only reading around 600 once i i ha added nutes to water im picking that is way to low.maybe i need to change nutes.

Do you think it looks like a deficiency?

.

Yes its a deficiency of information. Can you show a pic of the whole plant ?

The 1 that is having probs is on a scrog 1st attempt at that all up i have 7 and this is the only 1 showing these probs at the moment anyway i have done a few with good results 1st time coming across this prob the strain is possibly pineaple haze but not 100 percent sure had 1 of these in last grow and it done really well and good yeild 11 oz of 1
