Why do I have rapidly spreading yellow on my leaves?
Prilyfe13started grow question 3h ago
I have this yellow spreading on some of the larger leaves and it's moving super fast. Please help. I've done research and it says it's a deficiency, mostly likely cal/mag. I added that and it got worse, now I'm thinking nutrient lockout? The pH is fine. What do?!

Hey there it’s almost 100% over watering. Let the soil get really dry then water… if not that it’s possible you spilled some water with nutrients directly on the leaf…. Good luck don’t worry plants are very resilient they will survive threw almost any

Looks more like early nutrient lockout than a Cal/Mag deficiency, especially since it got worse after feeding.
Even if your pH seems fine, salt buildup in the medium can still block uptake. I’d suggest giving her a light flush with pH balanced water and then reintroduce nutes at half strength next watering
Also make sure runoff EC isn’t too high that‘ll confirm if there’s buildup

Hey guys, I have noticed that some of the upper leaves are turning yellow. I read that it may be because of heat stress or light burn but I'm not entirely sure and just wanted to ask what i can do to stop other leaves from having this issue. Anyways, what do you guys think?Week 15

Week 2, leaves yellow-ish mottling, pH too high?That's my guess for now. I was going to use Blumat Tropf hooked up to tap but house water seems too basic. Only way I can think of remedying is to hook Blumat Tropf up to reservoir and make sure the water in it is the appropriate pH. Will that be stable?6y ago

Should I flush? (Overfeeding)I think I have overfed my 2 dwarfs. Theyre showing signs like very stringy skinny new growth and yellow leaf tips. Theyre still growing and I dont want to stunt their growth, so all I want to know is if it is necessary to flush. Please tell me how to flush if so, thank you.

Losing colors :'(I watered only 2L of water without nutrients this week (pot 30 L)
You can see it on the diary photos, the plans have lost their colors (yellow).
I wanted to know what exactly it was due to, because I read on the net a lack of nitrogen but I would like the expert opinion
Thanks !

Magnesium or Nutrient Burn or?Magnesium deficiency, or nutrient burn or??? Only on the lower leaves so far, curling down was existing genetics - but the burnt tips are new and some have even curled up now. Probably 5+ weeks left so too early for natural dying off?

Yellow blemishes1 week old seedling is starting to develop yellow blemishes on initial leaves. Soil is biobizz lightmix, PH 6.2 from bottled water with no nutes, 150w led light is at 50% and 25-30cm distance. Is it a cal-mag deficiency, light burn, genetics, or just too soon to worry?

Lower leaves turning yellow and getting crispyLower leaves are still turning yellow/brown. See photo. A couple weeks ago I got a greenhouse to protect the plant from the rain. Outside temperature has been lower and there hasn't been much sun (mostly clouds) so I don't think heat is a problem anymore. Don't know the pH. Help!
