Alright peeps, here's one for you. Still don't know what it is. Pictures attached to Week 9, Veg.
This has been occurring since week 3. There has been NO spread, it is always localized to only 1-2 leaf blades and she is not stunted at all (largest girl). Please PM for more info5 years ago

My Green Poison leaf tips are burning not sure what it cld be. I was thinking magnesium deficiency jus off the simple fact that I have been using distilled water which doesn’t have any nutes the plant need (now using de chlorinated tap water) or is it heat stress or nutrient burn ?? I know my tent can get a little hot because of where I’m at but it’s somewhat under control. But if u have idea or suggestions for my Green Poison I’d appreciate it .Week 3

First grow. Start was a bit unstable.
Sticky 1 - Stress to cold / less light - Doesn't grow anymore and goes yellow. I think it's because the stress start / too shot ?
Taison III - Stress - needed to be repotted?
Any advice on my settings? Just started with a bit of nutr.
Thx!Week 1

Leaf damage/discolourationThe Skunk has been getting a lot of leaf issues. I have been trying to stay on top of picking them off as they appear in case it's rust or similar and can spread. It almost looks like cal mag deficiency, but I'm feeding cal mag each feed. This is the only one effected out of four5 years ago

Noticed these yellow spots this morning. Not sure if this is a nute deficiency, leaf septoria or too much light. My lights were pretty low as my tent isn't very tall. Have been watering at around 6.4 and recently started feeding a full dose of Big Bloom and Tiger Bloom.Week 6

Leaves yellowing 4 weeks into flower - a bit early?#1 Has started yellowing much sooner than expected. With 4 weeks to go, I'm not sure how much of a problem that is - what happens if I can't fix that? The other 2 are not affected and have same soil, sun and nutrient schedules. Bud production is going strong. Any remedy ideas?Week 15

What deficiency is this?Earlier, I added Epsom salts to fix purple stems, I’m pretty sure I over did it and I think this is a potassium deficiency but I’m not sure. I was being cheap and didn’t change res b4 moving over. Now that they moved tents, seems to be getting worse. How do I fix fast!? Pix in di5 years ago
