Problems in veg

so in week 5 of veg, getting some yellow patches on leaves on a few plants and can’t figure out what it is.

Under 600w hps, canna coco nutes + 1ml calmag per litre as using filtered water.
No bugs as far as I can tell (sticky traps and checking plants over with microscope)
If anyone has any ideas would be great to know

Just a blind guess . But do you have alot of wind blowing on your plants? Looks like physical damage

Whats your humidity and temps, ph, soil mix,

Or maybe are you spraying them during lights on?

@projectinfo bit embaressing but you might actually be right about the wind aha, had pest and ph problems last time so
was so set on trying to find out if it was either of them again i took my eye off air movement, just realised the one with the worst
of the damage happpens to be closest to a fan..
They were given a pyrethrum spray the other day but that was after the damage was there and was done in the dark just as lights went off.
Have rearranged the tent and will report back in a few days i it carries on/stops
cheers bro!

You should be fine then pal, also those pests, were they spider mites ?

If so, it may be because youve been super drying your leaves and giving more than ample oppirtunity for them to just walk onto your plant uninhibited.

They dont like moisture like being sprayed with water or humidity... If you want an easy way to see if youve still got mites is to plant some bush beans in a solo cups and put them in your flower room. If you got mites theyll migrate over and destory the bean plant .... Just throw the population away and start a new bean

Good luck bro

Hello mate just thought would report back, all problems have stopped sing moving fans around and growths started at a good rate again, thanks so much for that bro, would of pobably not even thought of it if you hadn't pointed that out aha.

They were just fungus gnats i'm pretty sure, but was into flower already so just got rid and cleaned everything out and started again so pretty certain i'm pest free at the moment.


again, cheers for the help bro
