New Grower leaf curling

[steelydan]

A couple of my plants, 20 days old have started to curl, or rather the leafs are. The other 8 are ok, all are under the same conditions?
any tips?
will post some pics soon
cheers

I'm having the same issue. Could be over-watering or a PH issue I believe. Mine have been curling down but staying green.

My last run they curled up and died which was due to PH or salt build-up I'm thinking.

I haven't really been able to figure it out though. Hopefully someone with more experience than I can help you out.

The pics will definitely help mate, generally leaf tips curled down means too much nitrogen so overfed, if they curl up and turn crispy/brown it could be calmag def. Could also be wind/heat burn but really can't be more specific without pictures :smokebuds:
