Yellow streaks between leaf veins

zerotwofivestarted grow question 5y ago

All three of my plants have light green/yellow streaks in between the veins on the leaves that have been present since about week one (week 3 currently). Could this be a magnesium nutrient deficiency, PH issue, or perhaps just overwatering?

It is a magnesium deficiency. Can also be set on by ph being out of range. But usually there is multiple issues with that. Just never hurts to monitor it. Little cal mag and you will stop the issue. Good luck and happy growing 🌱

Hello zerotwofive you have 2 problems. First you have calmag deficience and it may be because your ph is not good. So for calmag the best is to use epsom salts and for a quicker effect you can spray your plant with it. Then for your ph measure the drain when you water your plant and correct the ph if it needs to. You need to have ph around 6. Hope this helps you. Bye

Is this an Iron deficiency? The tops and new growth look too yellow and the veins are yellowing with a darker green in between Haven't fed much with nutes, when I did it's been low doses. I'm trying not to burn one for once. Not sure if its a deficiency or other problem or if I'm just worrying too much, looks off to me though. My problem with overwatering might be contributing.

Hello weed doctors, I need help identifying the problem and gathering advice how to enhance my second grow. It's only day 29 and my girls are sick, wh I'm in biobizz lightmix. Started biogrow on D24, the dose was 50% in 400ml water. Until D24 only rootjuice. Yesterday gave 1400ml each, with 100% biogrow, pH6.4 EC 1.1. My water is hard pH7.7 EC0.8, so I wasn't adding calmag yet. There was 400ml runoff EC 1.9 - why? What do I do?

I’ve got a problem but not sure what it is. It appears to be yellowing in the leaves, maybe a magnesium lockout despite me adding magnesium and calcium. I had the same problem with my last grow but it’s much worse with this one. I’ve checked and calibrated my ph pen. Im blaming the soil which is Biobiz light mix. Please see photos for week 4 and tell me what… universal_button_show_more

Clones are degenerating, help!It started with yellowing between the veins and I thought it's Mag deficiency, already ordered Epsom Salt. Today many leaves started dying. Is it just Mag def. or something else? Shouldn't be over watering.

Update on previous deficiency question Update on previous deficiency question The leaves got worse, its still only a few so not too bad. After doing some research i think it could be a Manganese, magnesium and/or Sulphur shortage. I fed some liquid calmag a day ago. I plan to use epsom salt if there is no change

Has anyone else heard of using epsom salt with gallon of water for magnesium and sulfur issues? I'm told you can water them or spray them during lights out. I've had some issues before with magnesium due to soil pH recommended by maker didn't follow it I later corrected it pH

My OG's are starting to yellow much earlier than I am used to. Pictures are taken on day 35 and they're supposed to be around 8 weeks of flower. Could the yellowing be due to high pH in the medium or maybe disease or am I just being paranoid?
