Hongostarted grow question 2 years ago

Please look at the leaves shown, orange and dried parts. I asked a similar question earlier but these look more damaged and I'm wondering if it's worsened due to my setup. Wind damage from fans? Water damage from humidifier? Light or heat damage? Managing VPD is tough. Thanks!

I'm going to disagree with my growmie here - simply because phosphorus deficiencies start on the oldest leaves and move upward - and I don't think this is the way it's progressed on your plant? I saw your question a couple of days ago and I honestly did not see anything wrong... but NOW, with THESE photos, I can clearly see that there IS an issue. First, let me tell what it's NOT... it's NOT wind damage or water damage or light or heat damage... but I'm not sure it's got something to do with your nutes, either. I'm wondering if it's some kind of fungus... so I'm going to ask - if you rub those spots, does it smear or come off on your finger? Or is it dry/brittle to the touch? If it smears or comes off on your fingers, it's going to be a fungus... if it's dry or brittle at all, it will indeed be a nute problem and probably a calcium/magnesium deficiency although that would show a yellowing to the leaves as well. A fungus will be the worst diagnosis... it comes from humid conditions and can only be solved by using a fungicide... in the case of SOME fungi, you would probably have to pitch the plant and thoroughly clean the entire tent but you should do research to try to identify exactly WHAT fungus it is..... I literally have no idea. If it is a calcium/magnesium issue, just adding cal/mag to your nute program should help if you're not already supplying it. Good luck... and don't hesitate to come back if you try something and it STILL doesn't work... we're here to try our best to help!

Greetings Hongo! My instant thought was what would I do if this was happening to me...and the answer was try to minimise moisture. To me it looks like water droplets have built up on or under the leaves overnight (condensation ) and when the lights come on the resulting burn may be what we are seeing here. One way to counter it is if you have to have that much moisture then a simply dabbing of the wet places when the lights first come on should prevent it. Should that be the issue. If its not obvious water build up then I would recheck your ventilation... extraction should be pulling 300-500l of clean air through there every hour. Hope it helps. Sticky Buds!

Might be a lockout in the medium with some PH issues as play. Does resemble calcium and magnesium but Gaia Green is loaded with Calcium. So if its not taking it up, I would assume it's because of an incorrect PH or to many other nutrients locking it out.

Please update your diary with feeding schedule and nutrients used as this would greatly help people here diagnose issues. I notice a few obvious things in looking over recent activity. Your daytime temp is 82, not too high, but high with 70% humidity. I also see that you increased the output of the Lights last week. One thing that is interesting to observe in many plants, including cannabis, is in high humidity environments, especially in higher Temps, young leaves at the top of a plant so reach upward. You'll only see this during the first few hours of the morning. The affected leaves MAY have been at that position last week and been burned slightly by the Lights. Only you can tell us if that could be the case. Good luck
