It means a slight excess of p and k, nothing much tow worry about, just don't up the flower nutes quite yet and make sure you use just plain water every now n then🌱👍

Yellow leaves with brown patches between veins.
Any ideas on what this could be? I checked the PH and it is right around 6.5. I did feed them twice last week as I was out of town over the weekend. When I got back the temp in the tent was °91. It's bad on one plant and starting on another. The rest look healthy.

Is this a deficiency?
Hello there, Today I saw that some of my plants have some curled and sad looking leaves (see pic). The soil is pre-fertilized and I currently use normal tap water (p.H. adjusted) for watering. My plants get 18hrs of light a day (approx. 300-400PPFD) Thanks for you help guys :)

Yellow leaf edges
I have a couple plants that are about 5 weeks old, and one has started getting yellow edges around the leaves. I feed them with worm tea, kelp, and calmag every other week, but it's a light dose so I think this is a deficiency and not a toxicity.

PLEASE HELP ME, my frozen black cherry is drying, what could I do?
It’s in the early third week of the flowering phase, but I don’t know some lower branches are drying out day by day, the first three photos shows what I mean, the last one is of the higher branches. Haven't watered for a day, but I don't think its a overwatering problem.

Why my plant is in shock i fixed the ph of watering .I suspect of this reasons:Heat wave/changing phase to flowering / nutrient locked/ over watering/. In
I lowered the ph of watering from 6.8 to 6.0 but this plant is still is shock and wont grow like others. Could it be a sign of changing phase from veg to bloom ? 3 weeks ago my first plant went to flowering and did the same color fading. Now that plant has good color

I have about 3 weeks left of flower, haven’t started flushing and had some deficiency in the beginning. The yellowing is starting to creep up to the smaller, upper leaves. I’m thinking a cal mag issue since I have not supplemented with that at all. Is it too late to give ?

Yellow leaf tips
Hello, I think I have a slight over-fertilisation. Could someone have a look at this. And could someone explain to me in this context whether and how bad it is that the water does not flow through when watering. I have never had water under the pot.

So looking at the last 2 pictures, what do you guys think? Lack of nitrogin or magnesium? Or is it because she doesn't need the big leaves anymore? Thanks for answering!

Do I have an Iron Deficiency, if so How do I increase Iron levels (Already using Calmag)
I think I have an iron deficiency. New Growth is appearing yellow. HYDRO Rain water - (20ppm) PPM 750-900 (just upped) Canna Aqua A+B Calmag (0.35ml/L) PH was 6.2 (as there was a calcium deficiency so I raised it slightly) PH is now 5.8 (I read lower PH is better for Iron Intake
