Con el amarillamiento de las inferiores, tambien podria ser falta de N. Revisa el PH que no sea que te bloquee alguno de ellos.

Dry yellow/brown tips, starting from the oldest leaves
What's wrong with the plant this week? Many leaves have dry yellow/brown tips, starting from the oldest leaves. Is it some kind of nutrient deficiency, and how do I fix it? I tested the pH of the drainage water and it was 6.8, I've flushed it down to 6.2 now.

Yellowing of upper leaves normal or problematic?
I'm in the final stage of the grow, pistils are starting to get orange. Today I noticed some upper leaves tuned yellow / are dying. The leaves in the middle seem fine. It's this normal or problematic? Thanks in advance for helping me out.

The tips of my lowest set of leaves are turning yellow. Start of week 3. I have not added any nutes to a soil mix of pro mix ultimate organic, EWC, and vermiculite. How should I correct it? Is it time to feed?

Is this Nute burn?
Is this Nute burn or something else? Using bio bizz grow, bloom and top max with “all in one” soil. I’ve recently upped the nutes in line with the bio bizz feeding schedule for my soil but it looks like the plant is freaking out at something. Thanks guys

Yellow spots on leaves
Noticed yellow spots on one of my leaves. It’s just on one plan (just one bottom leaf). Don’t know if this is cause of water being on the leaf or something else. Might just cut the leaf but I wanna know what it is 😅😅

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

How do I achieve the dark green leaves wedding cake wants? (More nitrogen?)
My plants are looking overall healthy but are not as dark green as I’ve seen most plants at this stage of growth, or like my plant on the bottom right of the canopy. I am feeding/foliar treating the same amounts to all plants. wondering what to do or should I just chill out?

I think it's calmag and lack of nitrogen but any ideas. I've been busy in the garden so have taken my eye off the ball. She looks in great health with praying full leaves but her colour is off. Any ideas would be taken with gratitude.

what's wrong?
this yellowing that starts from the edges and ends up drying out the whole leaf is only happening on the hulkberries (the fat banana looks great) so now I just don't know what it could be 😭

Losing vigor and yellowing
Sorry I don’t have a diary for this grow. I did collect some runoff on one of my girls so hopefully this can help for giving assistance. This is only my 3rd grow and the first 2 went very well but this one isn’t, all plants have lost vigor, are growing slowly and are yellowing.

Upward curling leafs, burned tips, 2nd week of flower
So I'm two weeks into flower now and my leaves are getting burned tips (I'm guessing nitrogen deficiency due to the light green of the leaves or some lock out) leafs are also curling upwards :/. And some fading on some lower leafs. Using biobizz roughly 10ml each Any ideas
