spots and burns

Hi ganja doctors,

What do you think this could be? maybe a nuteburn or overfert? or what?

after 2 more days

the new veg looks fine

I'm in soil, (atami kilomix if this can help....different from the mix I'm used to) experiencing this on a clone put into bloom couple of weeks ago after vegging 2 weeks.

this is my average schedule and ferts for seeds crops

I gave her very small ferts until now, almost nothing.....she has never received any real fert yet like top max or bio flores...only once Bio Vega (canna) 4ml/l and some fulvic acid Diamond Nectar and Bio essentials GH ...cause I knew the soil is very rich.....and she was also repotted when got into bloom

her mother showed something like this in the very early veg....with no bad consequences though....

thanks for your attention!

maybe spider mites or some other pest?

I checked many times, with lenses also, and could see nothing like that...

Those are not from insects.

Did this show up just after you switched to HPS? Man you are one detailed grower. LOL

The new growth looks deficient.

The old growth looks like metal/salt accumulation from using tap water.

many thanks, this makes sense, could be salt accumulation...new veg is very ok now... last water I gave enzymes and will now restart feeding...
