Jellystarted grow question 2 years ago

Deficiencies... calcium and potassium .. and I think phosphorus is headed your way as well... If you're not doing bottled nutes, look into bone meal and Langbeinite for your P and K ... I've used Langbeinite 0-0-22 before but it doesn't dissolve easily so I used one tablespoon as a top dress once a month throughout the grow...
Good luck!

it seems to me that you started having problems after the flora started, you can see that it's not an excess of nutrients because it was losing color until it started to burn, and you didn't exaggerate in anything from what I think, some very clear signs of lack of calcium are those "burned" balls, unfortunately I don't have much knowledge in organic, but you will need to do a better coverage when you get into the flora, guano alone will not guarantee a good coverage

Nitrogen toxicity? Deficiency? Something else? Stumped!I don't get it. Is this N toxicity? Serrated upturned edges, clawing, slow growth. But how? FFHF 75% FFOF 25%. Just Cal-Mag water. No food. NLS in bottom 3rd of pot. Not wind burn. Not too hot/dry at all. N deficiency? Yellow leaves on first bottom two only. I'm stumped.

Older leaves are yellowing, brown/red rusty spots, dying tissue, red stems.Older leaves have brown/red rusty spots and looks like dying tissue in between the veins.
Burnt tips, and yellowing leaves.
The soil was really dry and my PH meter was 0.4 too high.
I gave each plant 3L of water with EC: 0.0 PH: 6.4 to check runoff.
Runoff was PH: 6.1 EC: 0.8

Is my plant showing signs of Nitrogen deficiency?Autoflower, day 40. Most leaves are in a yellowish-green tone or even completely yellow. I was mistakenly watering it with tap water, but when I noticed the yellowing, 1 week ago, I started watering with mineral water at pH 6.49.

Moin, bei meiner Größen Pflanze fangen die Blätter an von außen gelb zu werden und braune Punkte zu bekommen. Ist das ein Zeichen von einer überdüngerung? Alle anderen Pflanzen haben dies nicht. Oder zu wenig?

Critical Purple: Leaves slightly yellow.Just started my first grow. I1 placed the light high in the tent and the leaves slightly turned yellow. I lowered it yesterday to 18” over the top on the plants. Just wondering if I am on the right track to solve the issue. The plants are still growing. Minimal nutrients 1ml/gal.

What's the problem?Hi guys, basically for the last few days the problem hasn't varied too much but I can't figure out if it's my light or if it's coming from somewhere else. Some of my leaves are curling with stains either on the leaf or like a burn on the tips.

Deficiency or toxicity?Hello i'm not sure what's going on, is this toxicity or deficiency? She loojs happy overall but new leaves have weird color, curled down tips, some of em are yellow and some are brow - burned.. maybe it's because she's transforming into bloom phase, PH 6.2 but runoff is PH 7.1.
