Heat Stress or Nutrient Deficiency?
MMSC16started grow question 3y ago
Is this heat stress or lack of nutrients? Fading leaves, 24 days from last dry organic amendment (Gaia Green 444, 284 and worm castings)Raised serrated edges of leaves on tallest cola tells me it's too hot despite temperature in range (79F max temp, 65% RH. 16" from Light)

It's not heat, your heat levels are fine, and your feed is also okay. The issue here is light burn/stress. To address this, consider moving your light slightly farther away from your plant, approximately 5-10 cm. Additionally, if possible, reduce the humidity to around 50-55%. Keep in mind that 65% humidity is too high for the flowering stage

Leaf discoloration may be due to a lack of nutrients. I read your diary and I don't see a diet or EC parameters. For feeding, you can follow the regimen indicated by the brand of your product, or buy an electroconductivity meter for better accuracy. By the 3rd week of flowering, you should feed with more potassium at least once a week.

Tacoing of leaves is too warm. Is your light too close throwing a hot spot on plant. 82f is about the tops they can take without special equipment

I've checked a few other journals and the raised serrated edges don't concern me so much anymore, however - input on when to feed and visual cues aside from leaves 'fading' would be very welcome!

Top leaves turn dark and curl - What can I do?I've had Nitrogen and possible Cal/Mag deficiencies 2 weeks ago.
Mid last week I started noticing some burn a the tips, so i dialed nutrients back again.
By this weekend the tips of the leaves curled further and turned dark.
The rest still looks a bit pale, but buds look good.

Calcium deficiency?I'm not so sure if it's calcium deficiency, what do you think?
Watering 100ml of water minimum.
Using 1ml calmag/per 1L(and other nutrients like N,P,K)..soil comes nutrient free.
Should I water her more and add more calmag or is this a different deficiency?

Deficiency/toxicity?Hi, back again 😂 so the canooing has stopped on some plants but still present in some. I've also noticed the leaves to look a little off, is this the start of something I need to fix? They look pretty healthy other than that. The photos are of different plants. Thanks in advance

Why have the leaves on my plant turned pale and crispy?4 weeks into veg with auto and all of the leaves (including new growth) have turned very pale and dry, starting at the tips and receding rapidly.
I’ve used the same two part nutrient solution in the same quantities as I did with the previous same auto, so Disease maybe?

Not sure what is going on with this Fastbuds Crystal MethThe week has finished, and the plant doesn't look very healthy. Although it has been growing quickly, new and previous leaves and curling up. I am not sure what kind of deficiency or excess is this. Should I kill it and grow a new one?

Do I have an (Mg) issue?Leaves turn light, have black spots and 1 leaf rolls in upwards. It got Epsomite with every watering so I guess it's not a deficiency. Last time there was not even a drain. So maybe nutrient absorption is blocked? Should I flush? Is it to stressfull for this autoflower?
