When to start with nutes? Also how much...?

I'm 5 weeks growing, gonna keep growing for another week or 2 then start vegging...will they only need nutes once I've started vegging do ya reckon? (I'm using potting compost...)

if your 5 weeks growing you are veging now, u mean u will start flowering soon.. is this correct?

for veg give nutes with high N NPK
for flowering give nutes with high P NPK

read the bottle and feed as instructed.

what strain u growing? any pics

Just been growing them under natural summer daylight - got some lights and I'm gonna start the full 24-hour thing for a couple weeks to give the 5-inch, 4-leaved little sods some more growth before the 18-6 vegging stage...or should I just veg out as it were? They're VERY small for 5 weeks from all the pics I've seen on here...but then again Paradise Rox isn't supposed to be a big strain according to their site...but SURELY they must be bigger than 5-inches with little vegetation at 5 weeks...?!?! To give you an idea, each leaf JUST covers the end bend on my index finger, the leaves are good and healthy though...

(Don't really know much - its my first attempt, I've read some stuff on here and seen some videos on youtube and they're all MUCH bigger than mine at 5 weeks...)
