We have quite a few Cherry Punch F1's and I know they are sensitive to food so they are just in Happy Frog. This issue on one of them does not look like nute burn.
So... we started with tap water on all strains (Moby Dick, Malana Cream, Cherry Punch F1, Critical Purple Kush, and 1 Zkitlles). Our pH levels were very high at one point (9!) We have since switched to purified Nursery water and added Espoma Soil Acidifier. The pH is down to around 7 now.What's the PH of your water? Soil should be 6,5. Coco Coir 6,0.
Could also be CalMag issues, imo.
What kind of light are you using, and how intense / close?
The reason why I'm guessing light is if you look at the tips of the new leaves they look bleached.BESTVA 2024 Newest Upgrade DC2000 Led Grow Light with High Yield Diodes Full Spectrum LED Grow Lights for Indoor Plants Greenhouse Veg (2 of them) Aprx. 20 - 24 " high from the tops
Thank you. I am going to go and tend to them today. I'm thinking of raising the lights and I also have pH balancer ( see photo). I will update once I'm done.The reason why I'm guessing light is if you look at the tips of the new leaves they look bleached.
PH OF 9 IS VERY HARD. (dam caps lock) filter your tap water (RO) or just use bottle water here on out.Thank you. I am going to go and tend to them today. I'm thinking of raising the lights and I also have pH balancer ( see photo). I will update once I'm done.
This is our indoor set up:We have quite a few Cherry Punch F1's and I know they are sensitive to food so they are just in Happy Frog. This issue on one of them does not look like nute burn.
That's not bad, and kinda typical. Ours has been 7.6 every time I tested it.I just looked up the pH of the tap water in my city, and it is "between 7.3 and 7.6"
Another possible cause of leaf-tip chlorosis or necrosis is when the VPD is too high. That happens when the temperature is too high or the humidity is too low.
Definitely could be a culprit.Im going along the lines of your light is too intense. It may also be that tip sat in the soil directly causing it.
I agree for sureIm going along the lines of your light is too intense. It may also be that tip sat in the soil directly causing it.
Thank you. Along the way we had the Inline exhaust fan on high and then the humidity dropped to, around 43% for a few days (we are not living at the location). We added a humidifier, and are currently running at about 77° and 81% Humidity (the Malana's really enjoy that now)Another possible cause of leaf-tip chlorosis or necrosis is when the VPD is too high.

UPDATE: I raised the lights up and transplanted 10 of them from 1g to 5g. Still a long way to goWe have quite a few Cherry Punch F1's and I know they are sensitive to food so they are just in Happy Frog. This issue on one of them does not look like nute burn.
