Nitrogen/magnesium deficiency?
GronkLeaguestarted grow question 6y ago
Please can someone take a look at this?does this look like a nutrient deficiency?
I'm growing in coco and haven't used any nutrients until today(Day 22)... From what I've read online im missing nitrogen or magnesium.
The plant is yellowing from the bottom up and is a light green.

Your plant still has cotlydon leaves and should still be young enough to go without feed, or very little. I'm unconvinced it's a deficiency. Your in coco which pretty much rules out overwatering... but could u be allowing ur coco to dry out? You should NOT let ur coco dry. In that case it would show underwatering yellowing. Your lights look at a good height so it's not light intensity. Mabey and I mean slight chance it's a deficiency it be nitrogen but I'm not leaning that way.

Hi Guys i hadn't used any nutrients up till this point; is that not more likely to cause the issue?
Im only really focusing on this being the problem because of the following:
Water is coming from a filtered RO feed
Temps are a consistent 20-30 sometimes going up to 33c on the hottest day
No nutrients had been used at all
I'm using buffered coco withg perlite
I'm really trying to practice watering when the medium is drying
This is so confusing!
Thankyou for the helpful comments!

Hey mate. Looks a bit young for a deficiency. Id say check your water quality and temps in the tent. Nutrients can start to be added but ease into it at a portion of the manufacturers recommended ratios. They will be sweet once you get em going. Good luck bro!

Is this definitely CalMag deficiency? Check diary for video.Before I go to over the top with the CalMag in a stupid attempt to nurse my plants back to health I just want to know for certain what it is.
The leaves are clawing, bronze spots everywhere but the smallest of the 3 doesn't seem to be suffering as much.. what is it?!

pH is 5.5 but i have nutrients deficiency. Can it be the cold?One of my plants (in soil) has yellow leaves and brown spots, it is possible that it lacks Ca and Mg, but it's pH is 5.5. I wonder if this nutrient deficiency is caused by cold water (now I'm using it warm and waiting), low temperature or high humidity.

Buon giorno weed doctors, did anyone have similar uniform chlorosis at the top or maybe knows what's up? What could be the reason and the solution? ThIs this some sort of immobile nutrient deficiency or excess? Could this be caused by heat and light stress? She is 80cm tall and almost touches the lights in the tent. I'm usually suffering from Calmag and Nitrogen issues and haven't yet experienced yellowing from the top. Thanks

Unsure about waste of time without any nutrientsI keep seeing people say I NEED nutrients but I can’t get any. Is it not worth it without ANY nutrients? I can’t afford anything, not even calmag stuff. I’m thinking anything under 10grams, I’m just not going to bother let me know what you think.

Phosphorus? Potassium? CalMag? What is going on here?So in week 8 after flushing with EC 0.4 and giving extra PK 13/14 afterwards (EC 1.9) there are still problems occurring. I personally think it’s a deficiency of potassium and phosphorus. Can anybody give me some advice or tell me how to fix it? Thanks!
