Just coming up to week 6 and got yellowing from the bottom on one plant, looks like N def but they've been on 3 or 4ml grow p/l along with 4 ml bloom p/l but there's a mottled fungusy type of look, taking 2 litres every 2 days and started after thrips but only one plant, was thinking maybe systemic fungusy type thing going on but could do with some advice really, pics in diary here, cheers.

Use 4ml/litre per litre, every watering. They're definitely N hungry. The fungusy look you describe happens as a result of N deficiency - first they go yellow, then necrotic spots begin to appear (as the leaf dies, I guess).

It sounds to me like your watering might be a little out too... are you saturating it properly and making sure there's run off left in the tray underneath? Every 2 days sounds really often to me.

Hi mate, cheers for the reply.

I've backed off the feed but upped it again atm, it's only on one plant and seems to have slowed a little, They get to stand in the run-off for about 15 mins then I empty any that's left yeah. Have tried to stretch it out to 3 days but they get quite droopy at the bottom at 3 days, have been doing 2 days then next time 3 then back to 2 and so on and it seems to keep them happy with regard to droop. Not too long to go so hopefully they'll be ok.
