Calcium Deficiency ?

tiasmaaastarted grow question 3 years ago

Got a little deficiency, can't find what it exactly is. Maybe a cause of this problem is that they got 3 days of nonstop light because I fucked up with the timer just before leaving house for 3 days

Begining of nitrogen toxicity, cut back on nitrogen now that they are flowering. Also, always post pictures taken in normal light, pictures under grow lights are next to useless for details.

I agree with @Organoman... but just wanted to pop in here to tell you I grow ALL my autos under 24/7 lights so I don't think that's the problem (I do this to keep the temps up in the tent 'cause it gets way too cold even shutting them off for 6 hours). Don't know if photos react the same way, don't know if you're growing autos or photos...

Light stress/ light burn. if they looked fine before the fuck up, its not a nute issue. Just give em some kelp or seaweed extract if u have any, it helps with light and heat stress, and go easy on the other nutes for a week. When a plant is stressed, weak nutes and seaweed extracts help along with time to recover. If you pump her with strong nutes now she will drop her leaves or curl them even worse.

Brown leaves and red stems. Is this a calcium deficiency ?I had an iron toxicity recently that may explain the brown parts but it may look like calcium deficiency. There are many red stems too but it maybe something else like the bad Ph and overfeeding from the previous month. What do you think ? Thanks !!

orange sherbet crispy leaves. Close to harvest Fastbuds Orange sherbet first grow. I already harvested this plant but I’m curious what the issue was. The leaves were yellow and crispy to the touch. Other leaves looked fine. 2.5oz harvest but it dried really fast(7 days) and now smokes harsh. Don’t want to repeat this mistake.
