Hey guys I’m 6 weeks into flower and experiencing some diff issues with two girls same strain one the leaves are cupping up and the other is showing sign of nute burn but the buds on both are looking great should I just water with regular ph for next couple waterings or should I do a flush ? Thanks for the tips
Gday @Mitch1, I think the issue with the plant with the cupping leaves is due to your temps being a little on the high side. Try to get them down around 24 degrees or a little lower. The other plant with the burnt tips is a classic sign of too much nutes, A couple of waterings with plain ph water should help. When you do resume your nutrient schedule do so at a lower ppm than you were using before. Your plants look great and you are not far from harvesting so you will only have a small window too correct this issue before you need to start your flush. Good luck with your grow.

Well your not from the USA because your using metric yay! Haha
Welcome to the support forums.
What type of potting soil did you use? Did it have long time release nitrogen pellets like most hardware store brands do, would say something like (feeds for 6 months!)
Your temo is right on the top side of max and that’s why your seeing some cupping but not alot.
Definitely to much nitrogen, see how the leaf tips claw down? Classic nitrogen overload.
Stop feeding and PH your water a bit higher so your run off is 6.2-6.5.
Do you havea TDS meter? You need one…
What’s the TDS /ppm of the nutes going in and what’s it of the run off? What is the water your feeding alone ppm?
What are your lights and how far away are they out of curiosity?
I’d say your ph is a little low for a soil grow. You’re using fox farms bottles, did you complete the recommended flush on schedule? I would also be a little hesitant to say you have a temp issue, 82 is right about where I try to run my led grows. I would lean to say it’s a nutrient issue or potentially over watered, both will also cause leaves to taco.
With fox farm be sure to flush according to their schedule
Taco- ing leaves usually means too hot. Raise the lights or decrease temps. The ‘claw’ in your leaves indicates too much nitrogen. Soil grows should have a pH of 6.2-6.8.
