nitrogen burn

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...

Had a spike in nitrogen, doesn't seem to be out of control. It's fading color of leaves. straight water for last two waterings. When I noticed plants had slowed down and were very dark. One leave even burnt. Mid June in Canada, things are growing again. Wondering what damage I might have done...

Growing some gorilla cookies by fastbuds in coco and shes had issues throughout the grow unlike the forbidden runtz next to her. Currently feeding 1L at 5.8-6 ph per day. Since shes started pre flowering the top leaves have been coming out skinny. I lowered the water intake incase it was...

Hello guys this is my first grow I am growing in coco and feeding half the recommended dose it is day 27. I suspect it is magnesium deficiency can anyone help me it would be much appreciated what do you guys think is the problem and what can I do to fix it I am very worried and scared I was due...

Posting a bunch of images I'm not sure if it's nutrient burn or just deficient in nitrogen. The leaves are getting worse. I stopped fertilizing about a week and a half ago and just water. Should I flush or stick to watering. Could all of this be normal it's August in the Pacific Northwest. It's...

Hey all so I have been playing around with some bag seed, pheno hunting and decided it was time to FIM one of my plants, well I did and shortly after it seemed to be showing signs of what seems to be a nitrogen excess (dark green, clawing ends) but I was wondering if it could be a disease as the...

Hey guys, thanks for reading! This is my first ever fully coco run. I'm using botanicare nutrients and FloraFlex lines. Two plants (of 6) left. One is showing what I think to be a really bad nitrogen toxicity, the leaf ends are very curled under and some are slightly burnt. The other plant is...

Hello, I need your advice since I experienced an issue and I think I messed it up. I don’t have the experience to carefully judge and apply the correct remedy (1st grow). Q: Is flushing during flowering a good remedy when suspecting a nutrient lockout? Currently: Day 59 on Royal Dwarf Auto...

Hey everyone, for a few weeks now the bottom of my autoflower plants leaves are yellowing and they are contining to yellow. I believe it is a nitrogen deficiency, i have been cutting the leaves off but obviously this isnt a soultion. I am growing on Foxfarm Ocean oil and using the Earth dust...

Hey guys! I’ve been doing research and I can’t figure out what is going on. It isn’t very advanced at all but I would like to get it under control if it is a nutrient or ph problem. I’ve noticed that the leaves on the colas and most of the upper parts of the canopy are slightly yellowish/light...

I run a 4x4 setup with 600watt full spectrum lights. My lights sit about 18-20 inches away from my plants. I also do a flood hydro grow in Rockwool and right now, it’s only flooding once in the morning. My plants don’t seem to be growing or they are very slow. Some leaves seem super green and...

This morning I noticed on more of the bigger fan leaves a downward tip claw on my babies. The leaves look a healthy green but the tips dont look right.I think this may be due becuase of the 2-0-0 in cal mag plus I just started feeding them over the weekend. Im using a 10 gallon res with canna...

Had a problem with purple leaves that became obvious the last week of flower. As you can see the canopy facing the light darkened to purple, and the tips of a few leaves in one spot burnt a bit. The last picture shows that this was light triggered, the growth in slight shadow was still nicely...

Can someone confirm this is nitrogen burn? I repotted w maybe 40% perlite. (the rest FF OF). here's image: http://ibb.co/hXBRDa Here's image of a seedling I'm having troubles w also. What the heck? http://ibb.co/k7HSKF I'm new. W/ seedlings, they're under 750w Mars Hydro LED during the night...

[this was a link] please comment update: it wont let me post link because I'm so new:( Above image is of plant in question. Is anyone able to verify this is nitrogen burn and not cam/mag issue? The autoflower plant (either white widow or early miss?) is in straight FF ocean forest. It's...

the grow: i am growing quite succsesfully for the first time 3x white widow, under 3x150w bloom light (they are in flower). im using bio bizz products all organic with Light mix soil and grow + bloom fertilizer and top-max to help bud production (havent started that yet). temps are comfortable...

So, I really feel like I've got a deficiency happening here, but can't seem to get an overall consensus on what this issue is and I want to make sure I'm treating the correct issue. I believe ultimately it's a cal/mag issue, but would love to hear what as many of you think on this. Background...

I recently bought some nutes different from what I've been using, and I don't know exactly what I've done, or how to proceed. I've been using earth juice grow( everything is in happy frog soil), with botanicare pure bloom pro and botanicares liquid karma. I add molasses and Epsom salts to my tea...
