Leaf Clawing
Smowkabowlstarted grow question 5 years ago
I got some leaf clawing going on and I'm not sure why? Only 1 of 4 plants that are under the same conditions is showing the condition. The only new introduction has been some cal mag in very low doses (1ml/gallon). It doesn't seem to have slowed growth in any way. Any thoughts?

@smowkabowl Hi mate it looks to be root stress related maybe the substrate is too warm under the surface and is causing issues with adequate Oxygen supply to the roots
My suggestion would be to add a little cool water slowly to effected plants roots then apply some type of mycorrhizae such as Great white from plant success or similiar product
OGgrowsanswered grow question 5 years ago
it may be slight variations in PH or the substrate is soaked, the roots without oxygen cannot feed on nutrients properly. let substrate dry well between each watering and water in less quantity. if it persists you may have an accumulation of mineral salts in the soil, if so use a soil cleaning solution. good luck

Leaves are turning into dark green with a plastic-like textureI have 3 ladies in my tent. While the others looking healthy, one of them has a darker green tone with a texture like plastic and shiny. Everything is the same (fertilizer ratio, coco medium), however the one on the picture has a problem. What might be the problem folks? 😩

First timer seedling worries.First time grower, is this normal for a seedling? I'm currently on day 3 and noticed these guys have some dark curling leaves. Is this caused by over/underwatering? A light issue? Or am I just over worried? Soils feels moist. They are in Tupur, lightly buffered, in 1gal growbags.

Leave Tips Yellow and Brown on New GrowthThe leave tips of my plants turned yellow and burnt after i gave them a bottled nutrient feed (organic). Unfortunately i failed to measure the PH of the Water (it was probably to high). This was one Week ago and the New Growth still show signs that something is wrong.

Problem with plants in the 3rd week of vegetation.I'm posting again because I accidentally marked it as resolved.
I was using BioBizz CalMag from the beginning, but when I switched to Advanced Nutrients, I stopped because Ph Perfect Sensi Coco Grow A and B already contain CalMag.

End of Flower, Yellow and crusty leaves ok ?Hey last weeks of flower and I’m not sure if it’s fine how they are developing, as I started flushing this week they quickly started developing yellow crusty leaves.
Should I keep flushing them as I will cut them in 1 or 2 weeks or should I try to balance out missing nutrients?

This margin curl appears to have spread from one plant to 2 of the other 3. So I assumed not pH, not lockout, not nutrient based. Roots all great. I've culled the 3 and there is 1 survivor doing well but what was this? In the diary I mention using Temprid FX, Neem, Spinosad.

Maybe PH Lockout?Hello everyone, can you maybe help me? My Black Cherry Punch has some kind of problem. I suspect it’s a nutrient lockout caused by the pH value. I flushed it two days ago, and the drain had a PPM of 1000 and a pH of 7. The plants are at the beginning of the 2nd week of flowering.

Advise to flush or feed in VegDoes this is look like a nute burn, deficiency, or ph problem? The two plants that are growing a tad taller have had yellowing tips some curling downward. Don’t want to overreact and cause it to worsen, they’re looking healthy otherwise. Any advise whether to flush or feed?

Leaf-tips going droopy modeAfter my second to last watering the tips of all of the leaves started to droop a bit. I though it was connected to the night-cycle of my light, but it continues to worsen every day. However I only watered after the soil was dry too the touch? Is it really overwatering or else?
