Hi. My plants are on week 5 of veg and the leaves are curling upwards on the edges. Most leaves that are 1-3 weeks old have a purple line running through the middle of the leaf. I fed them w/ nutrients few days ago. Leaf temps are just about 24C (75F). Also the leaves feel harder and dryer compared to a week or two ago. Newer growth seems squished up like it has no area to grow. Here are some pics; This one is what i mean by ‘new grwoth looks squished’
Most likely your LED lights are too close to the tops. Even though the temps are fine, if the LED's are too close they will get stressed and cup like that. If you can provide pics in natural light I can check out the color of the leaves to check if I'm missing something. Those LED lights do us no justice to check the true color of the leaves.
Thanks for the replies. I am currently not able to take pictures under natural light because one of the main cola is not tied down to the pot but rather to an object that is not part of the pot and I wont be able to move it w/o messing the training up. I took a quick closer look at the plant, and i saw a single small brown spot on two different leaves. Also a few leaves through out the plant have grown abnormally; grown unevenly Im thinking that this is either a boron deficiency or a calcium deficiency like pap said. Any thoughts?
yet no mention of humidity...? look to the absence of water in your air in that grow space for veg keep that at about 70% Rh good luck ps the red stripe again poor temp control..see it as stalled sap
"Under LED you should give calmag every feed or every other ." That's how I was Learned ! Sent from my SM-G930T using Tapatalk
for the curling, if its not heat how close are the lights? for the brown spot what medium and what are you feeding? need a proper pic. the flash on your phone will do! i cant see what you mean about the purple stripe but vostok seems to know his shit.
- Humidity about 55% - 300w light @ 22 inches (recommended 24’’ for veg) I was able to capture better pictures this time... Darker in the middle, almost every leaf has it Another picture; Same thing, dark purple in middle and a bit to the sides Any ideas? Thanks
What light what medium what feed??? And no the pics aren’t better lol. I bet it’s just the light Making it look purple! Can you not turn the led off then take a picture with your phone is using the flash? I’d also move the light a few inches see if they stop canoeing
