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 have developed "claws" at the tips that bend downwardsMy leaves have developed "claws" at the tips that bend downwards.
I suspect there is too much nitrogen because I probably used too much root juice. (Approx 8ml, scale was inaccurate)
Now my question to the professionals: what can I do to fix the problem?

Am I overthinking things?Any idea what’s going on with these ladies? Or am I just over thinking. They just seem a little unhappy. Watered 750mil yesterday morning the last time before that was 500mil Saturday night. Could they be a little overwatered?

Too much nitrogen and underwatering?Hey guys, can anyone tell me what they want (or have too much off?)
I think the big one has a bit too much nitrogen is my guess?
I also transplanted them today and yesterday so they had a bit less water as usual the past days. Could that be it as well?
