What gives you the impression of bugs? I have not seen any but i have seen the odd leaf with a hole in but i assumed this was due to burn of some sort. If there was bugs what could i do to fix?

Those marks look like spidermites get a loupe and look under the leaves

Google spider mite cannabis and you will see what i'm talking about

Do those white dots on the leaves come off when you brush your hand on them? If not that is probably spider mites they definitely aren't easy to get rid of you need to start spraying immediately with different stuff so they don't build immunities.

I can't say much about the bugs thing but one thing for mag deficiency is just use Epsom salt, it's cheap natural and VERY effective not to mention you really can't use too much, Just add 1/2 to 1 TBSP per gallon and it will clear up and mag Def quick, another thing as you just moved to flower is blackstrap molasses it is great for pre flower and has mag in it. Look up Molasses before flower. Yours looks like it could be a little N deficient when you first flip over to flower she is still going to want N for her stretch I use 1/3 of my regular Grow nutes for that little N she craves for growth.

I hope so, i gave them a couple washes with soapand water in spray gun while i had nothing else, and removed alot of leafs from them also.

Tonight i have put the plants in the bath and washed them with the shower and sprayed them with CannaCure.

Cleaned the floor and walls of rhe tith a mild bathroom cleaner also.

Left the fans on blowing in the tent but left the lights off and fingers crossed this will hopefully have them done with.

I am going tomorder tonight other products incase this doesnt work.

I am quite lucky the plants was only flipped to flower 1 week today so no buds as of yet, just hope i havent over stressed them or stunted the growth. I was thinking would it be worth me putting them back into veg forna week to help recovery or would this not work now?

Thanks again for your help.
