Critical kush (2 problems need help please)

Basically the leaves on my plants are slightly curling up around the edges, and the sten of the leaves are getting a purple colour to them, I am led to believe that the leaves curling up are caused by slight heat stress, and the purple leafstem are caused by lack of n p and k, the plants are in 20l of canna coco and feed at the min is 5ml of canna coco a+b per litre, they have been in veg stage for 1 week today and they did 3 weeks cloning stage before that, lighting at the min is 2x 600w dual spectrum lamps turned down to 400w sl on lumatek dimmable ballasts, temps have been quite high throughout the this week reaching up to 32 degrees but temps are back down to 23/24 now and at 50/60% humidity


any info you guys could give me to get me plants to full health would be great thanks

heres some pics aswel

Anyone? Anything?

Reduce light, give water only for 2 weeks at least, there is no lack of nutrients there !

Thanks I've got an oscillating fan in the Room now temps are back to normal and seem to ok will post pic up tomoz

honestly from the pics the first thing i thought was heat stress.. it doesn't appear that you have burn anywhere... she loves cal-mag.. so add that and it might fix your purple-ing...

The purple isn't a bad thing. It is the underlying layer of Xanthophyll (like chlorophyll only purple). Some strains show it more than others. Looking great so far!!

You answered your own question regarding heat. If you corrected that they should be fine. Good job. Best of luck.
