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.

Should I cut off yellow leaves?Bulldog cookies, 5-6 weeks in flowering. The leaves started yellowing, not fast like a disease or something. I'm thinking about cutting them off. should I? Would it be better for bud development, or in this flowering stage is would be too much stress?

Sligthtly Yellow LeavesI'm growing 2 Mephisto Canna Cheese seeds. Canna #1 is looking very healthy and green. Canna #2 is healthy (ish) but its branches are more spread out and the leaves are a bit yellow green. I'm trying to figure out if I have a problem with Canna #2 before it gets worse.

Can anyone tell what is causing these yellow tips on new growth on this plant?I noticed my DLI was around 42 at the top of this plant so the light may have been too strong, or it could be a nutrient issue? Using CoM Stonington soil, plant is 26 days old. Haven't added any nutrients to the soil yet.
