Tips burning, brown spots
Anorakstarted grow question 5y ago
Hello growers! I have White Widow in the 5th week of flowering. Only top leaves are affected, some of them are turning pale yellow. Feeding her with NPK:18-12-18 and Cal-Mag. The brown spots are my biggest concern.
THANK YOU!!

Seems like Excessive nutrient + Light burn(and maybe excessive heat, but it could be due to light exposure), a hard combination that one make the other worse.
Check for light proximity, and if you use fertilizer take a time without, with only water.

It looks like nutrient burn with a slight lock out issue going on. Lock out could be from PH being off so check that and also get the nutrients down. If grown in soil I would “soft flush”.

Yellowish color at the tips and wrinklesMy plant has been yellowing for a day now, I think it is a deficiency of some nutrient but I don't know what it could be, I have thought about buying NPK. At the same time, there are also a couple of leaves that have slightly wrinkled the tip and have been half lowered.

Deficiency?I laid off the nutrients last week after some concern that I was overfeeding, but I think that resulted in a deficiency. (Some of the darker colors might be related to the strain? 🤔)
The third picture was taken 12 hours prior to the first two, so it progressed quickly overnight

Please help to identify deficiency / excess???7 weeks, autoflower, soil + perlite, giving water with RQS Easy Bloom (half a tablet per 3 liters), pH of the watering mixture is 6.5. The bottom leaves on one of the plants are turning yellow (starting from the tips) and slowly dying , while the top leaves tips look very burnt.

3rd week since 12/12 and chlorosis is getting worse !!! Will my crop be crappy ?Brought EC to 1.6, added 21ml of calmag, had to add 2L of osmosis water because the EC was 1.78. I changed the bad Ph probe and I let it fluctuate between 5.75 and 6. Should I remove the aluminium foil on the pot to let them breathe ? Not sure they are overwatered, I'm desperate

Bloque de nutrientes?? Ph?? O falta de calcio y magnesio??the bottom leaves have a yellow color, the smallest ones fell off completely. The upper leaves have yellow tones at the tips. I'm using biobizz nutrients and following the chart exactly as indicated in all the waterings. Could it be nutrient lockout?

I noticed for the first time 4 days ago that the leaves are starting to turn yellow in some spots. At first, I didn't think much of it, but I feel like it's spread significantly in the last few days. I'd really appreciate any tips :)I noticed for the first time 4 days ago that the leaves are starting to turn yellow in some spots.

Light or nutrient burn?Ive been having yellow tips on the tops of both my plants for some time now, I already raised the light up a bit higher than the maximum height the manufacturer recommends, but Im still having the yellow tops. Could this be nutrient instead of light burn?

What do these yellow markings on the leave tips mean?What do these yellow tips on the leaves mean? Are my lights to close? Looks like light burn to me and have adjusted the lights up 10cm for now. Still wanted to make sure since I thought they need more lights during flower. Thanks heaps
