Hello,as new grower i try to avoid mess as much as i can.I noticed this (photo below).The new growth set of leaves are closed.Is it early light stress or heat/humidity high/low?
Thank you!

Should we guess at your temps and humidity . I noticed one pot to the left looks like you water wrong and a lower leaf looks burned. Over feeding?
 
Yes i add once a small dosage of nitrogen ealier in the grow.Maybe thats why,also i blast them early at seedling stage with over 400ppfd.
I ve faced many problems and i try to fix them.
So this close leaves are not from light stress eh?

I m struggling to reach the optimal ppfds 400-600ppfd lvl in veg and etc.So thats why i m afraid of light burned and i m looking for early stage light stress.
Thank you overall mate.
 
The more info on your grow you can give he better someone can help. I honestly wouldn’t sweat that curled leaf , yet. Im confused about you saying your struggling getting ppfd up but think its light stress?
 
I ll post more photos and more details later.
I mean that every time i m trying to catch these optimal ppfds numbers i get into troubles.Maybe my inexperience confusing about a lot of light.
Last grow i end my flower at 350ppfd max...and thats not good .
 
No 350 in flower is real low. Weed loves light. If your light simply doesn’t make enough ppfd than you should add another. If its to much simply turn it down. To fine tune numbers you raise or lower the actual fixture. Obviously a decent meter is needed. There seems to be conflicting feed back on app meter’s accuracy but better than none I suppose
 
I ve the zeus 600w 2.9 at 4x4 tent.i m at 50% at around 80cm distance.I ve spot on par meter.Now i m around 330-350 ppfd.I ll be back with better full photos later at night
 
Back again .
After 2 days on 400-450ppfd from 350 direct not gradually.
Look these yellow tips .It doesnt seem through the photo so good...

Also look this twisted leaves,is it from fast growth of the root,wind burn or...?.This time i m not sure if it is by light cause the other plant doesnt have.Also no pests.
