got some clawing and curling

Hey there,

I'm about 4 weeks in from seed on my largest plant (the other plants in the pic are younger, planted later).Got a little clawing and curling on top leaves. Heat stress?

My set up : White Russian , DWC, Lucas Formula using FN Bloom, 1000 watt MH, 1000 ppm, 6.1 PH, Air temp 79 degrees , Water temp 68 degrees.

I had a hilarious realization last week. I noticed that Lucas uses ml instead of teaspoons for feeding schedule . My last three grows I used fox farm and their schedule uses teaspoons . I made a huge error. Thankfully I noticed within the first couple of days of adding food and corrected it.

Anywho, help with this blunder is appreciated .

Thanks

all you can do is lower your ppm i think 1000 is way to much for the stage your in i would think 450 would be max

here 1350 ppm and my girls are 1000 times bigger

Everythings looks good but I would lover you ppm like dr green said. Nice set-up too

Way too high on the ppm ( 1000 ), for those babies you should be around 250, not sure if I'd go 450 but you could try.

what strain are those? Damn frosty, man.

thanks a bunch guys. I lowered the ppm and raised the light . I'll post to update .

with your feeding heres a simple rule that works every time. check your ppm daily. if it is going up your feeding too strong. if its going down you can feed stronger. if its staying about the same you have it spot on.

set up looks great. very similar to mine.

oh and that little bit of curl on the ends doesnt look like anything serious. but good work on raising your light i was seeing a little stress in the edges f your leaves but sounds like you got it sorted
