Deficiency discoloration?
GrowBrosInc
started grow question 5y ago
I noticed some light de-coloration on the tips of one of the tops. Is it just because its new growth or do I have a deficiency? Thanks for the feed back.

Looks like the start of a cal mag deficiency or a ph problem makes sure those 2 are in line and you should be fine.

Not normal, maybe a magnesium deficit

That’s not normal, could be magnesium deficiency but I can’t be sure. How much Mg are you giving to the plant? It should be between 50 and 80 ppm

Is this light burn?
All my leaf tips are going yellow, even on the bud leaves. It does seem to be a bit worse towards the top of the plant. Is this light burn? I am using 2x 1000w philzon LEDs in a 3.5'x3.5' Tent and I had them at 10/10 brightness. I just reduced to 8/10. Thanks in advance

Drooping leaves
The water pH wasn't right before but it's been at 6 for the past 5 days and the leaves are still drooping and seemingly yellowing albeit at a snail's pace. Water her every 2-3 days + 0.5 ml of feed once a week so not sure what the problem is currently? It's an organic grow.

Normal Yellowing?
Is this leaf yellowing normal for mid flower? I’ve been feeding her Greenleaf Nutrients MegaCrop, Sweet Candy and Bud Explosion with some GH calmag.

Yellowing on leaves day 16, gold label premium mix
Hi, what's going on with my queen? It's an auto gorilla cookie that I transplanted about one 1 week ago. From 1 to 3 gallon. I use gold label premium mix. Thinking maybe it's a to strong blend? Appreciate all answers, thanks! (It has recovered and grown since transplant)

Should I trim off the damaged leaves?
Should I trim off the bad/damaged leaves or leave them on? I'm not sure if it will help or stunt the growth even more(I don't know if that possible at this point but still). Do they even have a function after they got damaged the way they have? Please check my diary for pics

Discoloration on new growth
Both of the Sunset plants are showing some discoloration on new growth, one worse than the other. I've been watering very little and infrequently per previous feedback. Wonder if it's a nutrient deficiency. Any thoughts?

Seedling yellow leaves
Two weeks ago I started these 3 seeds, all of them are in the same soil but two of them have yellow leaves. Maybe someone can tell me why. I think it is not normal in this young age. Please look at the pictures to compare the three plants. Thanks for your help!

Could someone help me to identify the issue my plant has?
This girl isn't looking healthy anymore and I need to figure out why. What I did: I topped her pretty early but she recovered well (you can see it in my grow diary). A week later I transplanted her from 0.5L pot to her final autopot 14L. After that she had a hard time recovering.

Yellow leaf tips only on buds
Yellow leaf tips, only on buds... It is mostly buds nearer top, but some lower as well. It is not happening to fan leaves... This is an auto, around day 60 (4 weeks of flower). I have stopped giving nutes for over a week already to deal w nute burn. But this yellowing continues!

Does this look like nutrient burn, or a deficiency? The PH is right at 6 and I did my nutrients for 3 gallons in like 4 gallons of water.
