¿Qué le ocurre? ¿Tiene recuperación?
Las California Kush no acaban de recuperarse. He regulado el pH y la EC de todas las plantas. Una parece que se recupera y está echando hojitas pequeñas de un color sano, pero a la otra le salen muchas manchas en las hojas nuevas.

The leaves have become glossy and yellow
The last couple of days, the leaves have lifted a bit again and bent the edges, and the leaves are glossy, was it a mistake to keep the light on 24h the first week, or what do the last couple of pics look like? (I have now set the mode to 18/6) so as not to fry the plant

Yellow leaves
my little GG2 is starting to lose many leaves (they turn yellow and fall even before drying) while the other is not having any problems (the only difference between the two is the "aggressiveness" used in the LST) it could be due to the flushing done (but less than 5 days ago) 🤔

Yellow edges to leaves
Hello fellow growers. I have noticed some yellow edges to a handful of her leaves. pH droped a bit today down to 5.6 but has been stable at about 6.4 previously. Photos from the last few days show this problem has been creeping for a couple of days. Any ideas?

Leaves getting yellow and rolling up
Hello. I noticed this morning some leaves have their ends getting yellow and roll up to the center of the leaves. Some other leaves have very tiny brown dots. Only one plant shows up this phenomenon, others are ok. Ph is 6.5 for watering. Any ideas? Advice? Thanks for helping

First time grower. Looking for suggestions.
Should I be worried about the slight yellow on the edges of the leafs? They don't looks very healthy. How often and how much should I water during this stage?

First Grow Help And Feedback
Hello Grower, OG Kush Flower Day 24: Lollipopped and defoliated 10 days ago. Can/should I defoliate again? The buds seem like they could get more light. Also, I noticed some sprinkles on the top leaves—could this be from too much P/K? Any tips and general feedback are welcome!

Can anyone tell what is causing these yellow tips on new growth on this plant?
I noticed my DLI was around 42 at the top of this plant so the light may have been too strong, or it could be a nutrient issue? Using CoM Stonington soil, plant is 26 days old. Haven't added any nutrients to the soil yet.

Yellow marks in leaf center and weird King Kush?
There seems to be some yellow marks developing in the center, this tends to be on the outer side of the leaf, especially during over/under watering? Could this be calcium/magnesium deficiency being that the water source is from reverse osmosis? Also, any thoughts about the KKush?

Lime Green Growth Tipes
The growth tips on my plants are super lime green compared to the rest of the leaves. Is this a problem? I'm growing in FFOF and I've given very little CalMag and P-T-K so far.

Yellowing new growth!?
New growth is yellowing is this nitrogen deficiency? And it’s only happening to this strain. Also growth in general has slowed. Temps. Have been getting down to about 66-67F Bc of the cold front that came through.
