Edges of leaves curling up a bit, no discoloration
DankyDuckstarted grow question 2 years ago
Serrated leaf edges curling up a bit with no discoloration. Have tried cal mag foliar spray, raising light, flushing with water (ppm just over 500 runoff from flush). She doesn't look unhappy, just wanting to make sure she stays healthy! TIA!

Shes looking quite healthy.
Curing leaves upwards also known as canoeing is a sign of heat/light stress.
But I don't think that's whats going on here. I don't think anything is going on here.
Your temps are good and your lamp distance is ok, could be closer.
However your feeding TDS numbers are to high in the diary.
900PPM for this little guy is to much. want to lower that down before it gets hurt.
Good Luck and Happy Growing!

I wouldn’t be too concerned about it.. it does look more like a heat or environmental type thing if anything..
I do see some very slight interveinal chlorosis starting on some leaves, which could be the beginning of magnesium deficiency

@m0use it's middle of plant, looks like calcium deficiency starting.
Why could be many reasons , solution only one ;
Good wet dry regime
Good pH
2-3 waterings just with pure water no additives
0.5 or 1 ml / l of CalMag depending on situation when you finished pure water waterings and she is drinking regularly . I tent to guess that's it's not lack of it, but problems occurred from not following above mentioned requirements ...
All the Best !

Leaves Curling inwards early vegHello I’ve noticed that the leaves are starting to curl inwards. It has been very hot over the last couple of days with temps in the high 20s and RH any where between 45-60.
So not sure if this is heat stress or something else. Should this just rectify itself.
Thanks

Light / heat issue ?I have I question for more experienced growers than me, and is this a light / heat issue ?
I turned up the lights to 50% and in 2 days I saw this result . Temperatures are higher also because of the heat wave , currently at 27-28 C when light are on. Air humidity is 60 - 66%.

Is this Light Burn or a Nitrogen Deficiency? For Science!I have canoeing leaves from either light burn or a nitrogen deficiency. The 240 watt light is close but at 50% and the the deficiency is from taking out veg nutrients. Is it fine? Or should I drop my intensity down even more?

Heat stress, nute burn and light stress?It was very hot in the past week with temperatures reaching 32°C in the tent. I was worried about heat stress. This week I’ve been more careful about the light height since the plants are still growing upwards, but there is a big heat wave next week in my area.

Yellowing/brown tips of top leaves. Heat-burn, light-burn or both?Top leaf tips turned yellowish, brown with curling. I'm leaning towards light burn as the cause, but noticed it started occurring during the recent hot weather. I've raised the lights, but am wondering if this could actually be related to the heat.

Recoverable? Cut Around? No harm done besides yield?Heat stress plus some kind of lockout due to topsoil drying out. PPFD set to 900 for 2 wks, + dried topsoil. Lowered light intensity, flushed with water. Color has mostly returned. Sugar leaves affected. Is this fine, recoverable, dangerous to smoke?

Leaves rippled ? What causes this?These are pics of day 13 seedlings. The larger leaves show signs of something but I don't know what. They are Blue Dream Autos in a 50/50 mix of Happy Frog and Ocean Forest. Temps have been 74 degrees F with 50% humidity the whole time. May be nothing but this is my first.

Twisted leafs inner partLeafs are twisting but mainly inner part. See the photo. And it does not progress. It stayed at the bottom of the leaf
I assume three factors:
Wind
Excessive humid
Cold nights
They got Nutes at all, only from soil (pragron lightmix)
I would say shity PH, but i check it every time

Sick plant, nutrient toxicity?Few leaves on my plant are beginning to burn, plant was always at least 18” away from my viparspectra xs2000 light set at 50% brightness, so I doubt it’s light burn. Temps are always 73-78 inside the grow tent, this strain apple fritter is sensitive to nutes, happy frog too hot?
