Are you keeping a wet/dry cycle? These kind of symptoms often occur from over watering.

What are your rootball temps? 18 celsius is bare minimum, much below that and you will experience nutrient uptake problems.

I can't see the pics very well on my fone but that second pic looks kind of like a mag def...

But again, I have seen mag def's from over watering too.

Make sure to lift your pots and check the weight before watering next. You want them to be nearly dry so will feel quite light.

You are on week 6 so not long to go.

Just keep your eyes on the wet and dry cycle next time and keep rootball temps around 20 celsius.

Good luck!

Looks like a combo of overwatering and too cold roots?

Get those root temps up, especially during lights off and get a proper wet/dry cycle going....

what dose nutes are you feeding also?

hi thanks for the reply biobizz fishmix and bloom and bio heaven are the nutes every other water half the recommended strength of fish mix what would you recommend for warming up the roots an electric blamket would that do it and to what temp would I set it at ?

thanks for the input thinking about it the last two weeks I haven't been letting them dry out as much as I did before so flushing them was probably the wrong thing to do

so what sort of thermometer would you recommend for measuring the soil temperature and would an electric blanket under the plastic saucers do the job I have always watered them at bottom of the tent temperature about 19deg from water that has stood in that tent for 24 hours

Its a type of rust ie a fungal disease, Myclobutanil may control it, that has been on your plants for some time, the room will be infected, I suggest useing essence as an organic pretreatment, then every two weeks in future grows.

Hope this helps. Ot1.

Yea an electric blanket under the inner floor of the tent is ok, I use tube heaters with a thermostat for vivariums which does an awesome job.

Search on ebay for hygrometer and look for one with a remote probe. Should cost about a fiver.

Was thinking of mentioning a possible fungal infection as ot1 just did but I can't see the photos very clearly so didn't want to worry you.

In my experience, once you sort out environmental and feeding issues, the plants seem to fight off fungal infections. Maybe brew up some plant magic essence to help fight it and have a good clean of your tent and equipment once you've finished your grow.

Good luck!

Thanks for taking the time after further research it is a rust fungal infection hopefully the plants will finish flowering without too much loss of nugs I have ordered the essence you recommended and I will use that in future improve my ventilation and a bio screen on my intake thanks again
