im a nexbie

hi. i have 4 cuttings. i am using growells advise.
when i got the cuttings a couple had white/yellow patches on them. as they are growing, which today is day 5 there are more yellow/white patches and dots on them.
i am using a 600watt sodium light which i was told by almost evryone i asked that it was fine. i think i may have put the light to close to the cuttings. but now i have highed it. 150cm away from cuttings. i am using canna coco professional soil.
the nutes i am using at the moment is rhizotonic. 10ml per 2 litre of water. trichoderma 1 gram per 2 litre of water. i drop of superthrive per 2 litre of water and canna vega start 10ml per 2 litre of water.
im obviously doing it wrong as i keep being told different things by different people.
im worried about the yellow/white patches.
any advise gratefully recieved. thanks.

well thanks for all the advice!

pictures will get you more comments....descriptions are hard and you won't get accurate advice:thumbsup:

The best advice is to fill out the troubleshooting (at the top of the plant problems forum) and copy and paste it here. Without any knowledge about your ph, ppm, water source, temps, etc., its impossible to give any sound advice.

Some pics would help too.

Happy growing :jointsmile:

i have attached (i hope) two pics of the cutting. im really sorry but there not good pics. as my cam is crap. i hope you can see the one pic has yellowing round the edge. the other leaf can you see spots. especially on the left side? can any one shed any light on this plz. would be very gratefull.
thanks.
:(

and i ca not see hwre to fill out the plant problem form?
