toxicity

hey just a question about nitrogen toxicity I think I messed up I'm growing autos dark purple is the strain I'm running a light schedule of 18 to 6 and a mars 600 led in a 4x4 tent now I am using fox farm nuits as there is only 4 weeks until my autos are done and there very much so in...

After some troubles this plant has bounced back, but now it started having nitrogen toxicity problems, I believe. I think this is the case since the leaves are all dark green and clawing/bending downwards. The problem started after I went from a ppm of about 500 to 650 (base RO ppm is 200)...

Hello, here are two photos of the same grow, same system. Two of the plants have nutrient lockout and two are healthy as can be. I've included one photo of each. the top photo is a Erkel and the bottom photo is Zod. The Zod is locked out and the Erkel is doing great. My tds is 620 (500...

The plant has been like this for most of its life, the top leaves seem fine but the bottom fan leaves keep yellowing and dying. Was possibly a nitrogen toxicity due to curling leaves but is in flower now. Possible nutrient deficiency ?? 11 weeks old "autoflower" purple mazarr. Had to change...

This is my second grow and I've seen this discoloration in 2 plants so far. it doesn't seem to stunt growth but it's ugly and may be a serious problem later. If anybody knows what this is and how to fix it Id appreciate the help.

Hey, my recent grow is mango kush. it's week 5 and the trichs are easily 50-70 amber more like 80%, accept 1 of the 6 plants is at about 55% amber. Has anyone else experienced this strain flowering very quickly, or know of any factors that attribute to strains flowering faster than normal? I'm...

some leaves have crust like shapes on the edges with black spots on top. But the bottom of leaf is clean this plant is 9 weeks into flower

Been using same Britta filter since December and recently got a new one. The old one mightve been letting chlorine + others through im not sure. Looked kinda like sulphur def but I was feeding +/- 1tsp epsom every watering for mag/sulphur up until week ~5 of flower. Then stopped to give gypsum...

So, I transplanted some Royal Kush clones into standard 2 and 5 gallon pots. The soil is last season's FFOF, with some old roots and organic matter in it, but had been rained on all winter so it should be pretty much flushed of nutrients. Ph'd @ a 6.8. Just for kicks, I added a dash of Anasazi...

I'm having trouble diagnosing what the problem is with my plants. This bad new growth started about 2 days ago, 1 day after giving them a relatively strong nutrient tea. Initially I thought the problem could be nutrient burn or nitrogen toxicity, but the leaves are not clawed and the burn is...

Good Evening and thank you for stopping by to try and help diagnose the problem. So I started a few plants in 3 gal pots with FoxFarms ocean forest soil and fed 0 nutes for the majority of veg phase. After several weeks, these plants looked very healthy with tight node spacing. I was planning...

So I'm experiencing some lime green colorage on the new growth. I'm in the first week of flowering and it's stretching like a maniac so I'm thinking it could be due to that, but the leaves are dark green on the outsides of the lime color. It's not like a light bleach where the whole leaf is...

Hello, wondering if anyone could shed a little light on my problem. I'm currently growing Short Stuff Tha Shiznit (journals on here), 13 days since sprout, and on Sunday see started showing a few signs of a possible deficiency/toxicity. The problem area is currently just localised too the...

Here's some info: What Strain is it? I don't know (bag seeds) Is it Indica, Sativa or Hybrid? What percentages? Both, I don't know percentages Is it in Vegetative or Flowering? Vegetative If in Vegetative Stage.. How long? About a month Indoor or Outdoor? Indoor Soil Hydro? Soil If Soil... What...

I've read up a bit on potential issues and have not found a good match IMO that would explain this. There should be some yellowing or discoloration if it was Manganese or Potassium deficiency.? Hoping to get another set of eyes on this. New growth is very healthy and vigorous otherwise...

Background: some leaves became like this shortly after applying 4-4-4 pellets including calcium and magnesium, then soaking the soil. The plant is 6 weeks old, in veg under low light conditions. Also, why is this plant getting pistils that turn orange if I haven't initiated a bloom cycle yet?

Dark green blades and sharply curved tips. If you think this is something else, please comment. This plant is on liquid fish fertilizer 5-1-1.
