I would be curious if newer growth imporved with a slight light strength reduction. Even 24 hours is noticable if you take lots of pictures or have a good memory. The curve of the leaves looks like the recent light stress in my tents.
Chuckle weed guru. Get your points. What a joke of a reply. You didn't even help answer this kids question one bit. Just cause you seen his top soil dry in the picture doesn't mean they don't water it. Should brake it down better. What is your feeding schedule look like how often do you water. And with the light comment wtf. What are you running with your light equipment. How close or far are they away from your plants and if you have a dail what's the output you have it on. Loadpack516 my best advice for ya get the fuck off this bs forum grow your smoke take notes each run and learn how the plant works and start daily in your mistakes you have learned. People can tell you and give you there recipes to you and it well never be the same results cause there not growing it for you. Enjoy the mistakes you make and get a better joy off the result from improving it with each grow. It's a art and takes time.
This why rollitup up is a joke. "What light intensity". You think this kid has a par reader to be able to commit back and tell you what his light intensity is. Internet warriors. You don't even explain what light intensity is how are they suppose to reply back to that kind of question? It's not light strees. If anything people need to be asking him what are you feeding and how much. Looks of it it's under watered and over fed with the slight and very slight start of light shade of green in upper leaves. So we know it's not under fed since it's starting from top of plant and not the bottom. So many variations that no one has commit about it to help this person question. Just simple dumb remarks. That don't help them at all
Slabreal raises a valid point you will get a large variation of advice on here some helpful some not so much. Im not going to attempt to diagnose your plant youll get plenty of peeps to chime in on that but you should get yourself this lux meter to help with your lighting UNi-t btu lux meter its like $30 dollars it really helps with light distance and gives you a fairly accurate ppfd reading. Also this par meter is $500 aud and compared to top end devices this is excellent value and has been reviewed and tested with apogee par meters with very similar results. If i were you i would think back to when your plants were healthier and did you change anything like lighting, feed strength any enviromental changes watering practices etc. Good luck
