Nitrogen/magnesium deficiency?
GronkLeaguestarted grow question 4 years 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!

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

WHY?? Still looks like Calcium Deficiency?? HELP!!!Can Someone Please tell me what is going on here? I have a detailed diary if you have any thoughts on why it still looks like a Calcium Deficiency. Plant looks healthy except this. First time for coco (bagged & prebuffered), grow dots, and wick bases so I am at a loss.

N issuesThis girl suffered from N deficiency very early. So I gave it nutes. Nutes gave it N toxicity. So I flushed the soil with ph’ed water. You guessed it, it’s lacking N now. The problem is the pot is still very yet and heavy so I don’t know if I should water with nutrients

Emerging Issues - Week 9At the beginning of the week, I noticed the tips of the leaves drying out. Now, one out of the four plants has completely yellow leaves. Could it be due to the increased Biobizz Bloom dosage? For more information, please check my journal. Regards.

Lower leaves dying off. Normal or deficiency?Week 4 of flower and the lower leaves are dying off pretty quickly. I had the light hanging too low for the last few days so I raised it. At first I just assumed the lower leaves were not getting enough light but now I’m starting to wonder if I’m having deficiencies.

Suggestions or commentsComments or suggestions on my grow. She seems to be doing alright so far. Looks a little pale green. I just started nutes on Monday, GH Flora series, hopefully the color gets better. She’s due for water probably tonight. Wondering if I should feed again or just water.

Week 7 autoflower Cal/Mag deficiency fix.Week 7 autoflower in OFFF using RO water. Looks like a cal/mag deficiency after doing some research. Should I flush before adding cal mag to rectify? Then should I half dosage like other auto flower nutrients with all future water and feeds? This is my first grow
