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

Lockout or deficiency?
I have an issue with a girl. Newbie alert. I feel it’s either calcium def or nut lockout. I fed with 1/2 rec BAC grow feed and it didn’t get better, so 2 days after I gave a flush of fresh water. Now it’s really trying to grow, it’s kicking out new leaves but it’s stunted

Heading into about 3rd week of flowering and seeing some yellowing
About 3rd week of flowering but I have been seeing yellowing leaf tips starting on top newest growth first and now seems like I'm having older larger leaves yellowing and burning now. Not sure if this is lockout or a deficiency or something else?

Leaf Diagnosis
Could someone help diagnose this leaf problem. It's less than 2 days old. Aañnnnnd, 2 days ago I accidentally set the ppm to 1700? I've since dumped the solution and got it back down to around 700 ppm. I'm hoping someone give me some triage pointers. Should I trim those leaves?

Hello all, I am having some issues with my outdoor grow. It seems the leaves are beginning to turn yellow. It has not received nutrients I’d say in about a month. The main reason for asking is because I do not want to over correct by adding nutrients if that may not be an issue.

Unser erster Grow! Wir haben Nährstoffbrand, wie schlimm? Was können wir noch tun? - Dünger: Canna Terra Vega - Erde: COMPO SANA Qualitäts Eerde - 50%
Vor genau einer Woche haben wir einen Nährstoffbrand festgestellt. Die Symptome waren zunächst eher schwach, mit einzelnen, gelb hängenden Spitzen. Nun sieht es so aus wie auf den Bildern. Haben bereits im nächsten Guss ohne Dünger mit ph 6,3 Wasser gegossen. Was noch tun?

I noticed that the lower 2 leaves are yellowing and I think that are a little crispy. I topped the plant at the beginning of the week ago and I removed the first pair of leaves three days later ( yesterday). Do you think is this a problem? What can I do? Thank you. Peace

Nutrient burn?
Hello I have one plant with yellowing leaves that are also curling downward. Only one plant of 6 has this problem, I suspect maybe this one is just sensitive to the nutrient rich soil? I am using fox farm happy frog and have added no other fertilizer. What to do, flush all?

Discolouration of some leaves
Is the colouration of these leaves someone to worry about? She’s a young, 2 week old Wedding Cheesecake auto and I’m new to growing and just want to make sure she’s ok! She’s growing in a 70/30 split of coco and soil and has only been fed water so far! Is it nute time?

What is this deficiency?
They started off with some brown spots and progressed. Is this phosphorus? I have been feeding with .5-1ml of dyna grow bloom and 2ml of cal mag per gallon watering at about 6.3-4 ph. But i recalibrated my ph pen and did one water since.
