Large fan leaves tips curling down

[giz2k14]

I have 3 plants about 3 and a half weeks in veg. They're in bio biz all mix soil under 600w hps. They're growing lovely expect for large fan leaves have started to claw down at tips any suggestion what it could be ?

My guess would be too much N. I'll bet your leaves feel like leather or plastic too. If you giving nutes stop for a while till they look like they need it. I'm not a soil grower so if your not giving nutes I don't know what to tell you to fix it. Maybe a soil grower will chime in.

he has no control, He is using a HEAVILY pre fertilized soil. No control of nutes, at mercy of soil. Not much you can do. What are your canopy temps? r/h?

Leaves look perfect. Nice color, good shine to them, and I bet all the top leaves are pointing up and loving it. I would say you are doing a good job, and it is perfectly normal for a large fan to droop a little. Peace

all mix is quite hot i normally go light mix for a bit longer hit with the all mix for final pot up redy for flower, light mix gives you a bit more control, temp looks good, but whats your swing on lights out? (or are you 24hr?) if a tiny bit of claw is the worst thing about the plants then id not panic, your not feeding (as such) as long as ph is good id ride with it unless it progresses

Thanks mate all other leaves are fine just the largest fan leaves having the problem and their huge considering they still young if it is to much nitrogen I will just keep using plain water untill it's been washed out

18/6 lights yeah only problem is that the largest fan leaves maybe two or three have a claw at the tip ph is fine if it gets worse ile just flush the soil abit to leach out some of the pre fert

That's why I'm not a soil grower.
