leaf tips seem burned .is it nutrient burn ?????:w...

at this stage in flower a tiny bit of nutrient burn on the tips is almost a good sign, but it's nothing to worry about, plus with the flushing it should start to fade all on its own. Hope this helps growmie ! 🚀

Generally it indicate an over feeding or a high temps issue. Your temps are correct so it's a slight over feeding. Nothing harmful at that stage

Hi, no concern about that little nitrogen excess. More concern about the RH... try to rise your temps thats lowers the RH.......get a small infrared heater with temperature control and set it to 26 degree. You will see your rh drops.

@Nanito hi friend yes a little overfeeding but don't worry you are very close to harvest now What I would be watching out for is complications due to your humidity levels 70% is very high for sticky resinous buds and you run the risk of running into issues like botrytis (bud rot)

It's definitely nutrients burn but very, very, very mild so nothing to worry about. I suggest stop using root grow as it's only meant for the seedling stage and maybe safe to do a single flush on your plant to move excess nutrients away, make sure you check your pH level after you mix nutrients and be careful of mixing different brands together. This plant looks beautiful though and is probably going to give you some lovely product!

Hello my friend Do not worry, your plant is beautiful. If you have doubts about your nutrient intake water once or twice in clear water pH 6.3 and it will be back to normal. If this persists the leaves react differently depending on the deficiency or excessive intake of nutrients. May the strength be with you 💪
