I need help determining this issue. I haven’t seen this before. The leaves have this gloss film on them. I didn’t spray anything on them. I didn’t change the feeding. This is the only plant out of the three that has this. It’s week 4 in flower and I noticed the leaves and it started spreading...

Hi all, Those plants are 30 days from seed. The soil is "empty" - no added nutrition. I added Perlite + vermiculite + some hummus (less than 5%). I gave them advance nutrition grow a+b and cal mag since second week, almost every watering. In the beginning , half of the recommendation, then...

In the top image, I noticed chlorosis on a few of the upper leaves in one of my amnesia haze auto flowers. I was away for one week not monitoring plants. I had water bags attached. I think I may have given only half as much Cal mag as other plants. I think this plant got 1 ml of Cal-Mag...

So I started noticing brown spots the last couple of days and was told it shouldn't be too concerning. But today I went into the tent and the brown spots have moved all over my plants. I'm growing in coco soil with Gaia Green all purpose and bloom. I'm pretty new to growing and think it's a...

Hey everyone. Just need a pair of experienced eyes to spot the deficiency in my plant which is currently vegging at 6 weeks from seed, at 450ppm and pH of 5.8. The reason I kept the ppm's low is because I noticed burnt tips for newer leaves and held back on the nutes, but that seems to have...

Since I started using tap water, I have noticed the start of what I thought to be calcium/magnesium+nitrogen deficiency with the brown spots and yellowing/dying lower leaves. Luckily I was able to harvest that before too much damage was done. But as I am now seeing it happen on another plant...

Hi guys, I use AN Sensi line plus some extra nutes since 2018 and I am very pleased with them, very good base nutes. Grow and Bloom have of course different nute ratios, but someone pro could explain why is there such differences? Calcium: Grow: 3% Bloom: 2,1% Sulphur: G.: 1,3% B.: 0,4%...

Looks like calcium or phosphorus deficiency to me but I’m not sure. Can I please get some help? Leaves curling and copper spots. I only use 6.3-6.5 OR water. Gave it’s first cal-mag feeding yesterday. Gelato Autoflower

Hello friends! I've been a long time observer and grower, but never contributed to the community, because I thought that I don't have anything to share. Every time I have a question regarding my grow- I come here to read and to learn from those with more knowledge and experience. Now I'm in my...

Hi everyone was looking for a bit of help does anyone else think this could be calcium deficiency? Under a 360w led light not feeding anything yet in a 1.5x1.5x2 meter tent

Kinda a newbie grower still after a ten year hiatus so please bare with me. The first two cycles of my grow this has happened...I take one of the big colas and start snipping the buds off the main stem I noticed this.... Is this just due to lack of light getting to the center of big buds or...

So last week I noticed early signs of a nitrogen deficiency and this time it looks like a Cal deficiency? NOTE TO SELF: If vegging plants 3 weeks longer upping my pots by 2 gallon is not nearly enough.... (I normally don't have to feed at all during veg). What do you all think, early Cal...

hi everyone! First post, first grow. I'm learning a lot but I am stumped right now. I'm growing outdoors in zone 7b, so far my plants have handled beautifully without having to monitor PH. Temps have dropped so that its 60F at night rather than 75F. I keep them in an unzipped mini greenhouse at...

I’m a new coco grower and I can’t tell if I have a deficiency or over thinking it. Your help would be much appreciated! I am growing under LED light which is making the “issue” areas easier to see (pic show both LED light and normal lighting on problem areas). Lower leaves are more pale, a...

Found this while researching different shells oyster etc. and thought I'd share it. Nice easy to read research paper on using egg shells in your soil. This should enlighten anyone not understanding the importance of calcium. Enjoy. http://www.rjlbpcs.com/article-pdf-downloads/2019/24/491.pdf
