Yellow streaks between leaf veins
zerotwofivestarted grow question 3 years 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

Does that look like an early deficiency?Hi everyone, what ya thinkin'
What kind of deficiency could that be?
My bet - potassium.
last portion of water was ~6.2 pH
I wasn't feeding her nutes for ten days by now.
Because previous runoff was ~2000 ppm. I thought would be a good idea to do just water for a while.

Blue Dream Autos with Downturned Leaf Tips23 days old. One started showing downturned leaf tips on new growth; others followed. Looks off-color, at least one is in early bloom. They’re in coco, 3-gal pots, 480W QB at 50cm, 2.2 EC daily, no pH check. Problems started after adjusting watering for larger plants. Any tips?

Interveinal chlorosis and dead spots on leaves, deficiency?This started appearing about a week ago, after I watered until runoff with plain water. It's on a couple of leaves higher up both plants and seems to be progressing. I am feeding advanced nutrients Grow Micro and Bloom but have been using very low doses, like 1ml/L.

Slight Leaf Discoloration. Early zinc deficiency?Girl showing slight discoloration on newer leaves. Mostly interveinal + little on the tips. Guessing it's an early zinc def. but would like another opinion. Watering sparingly at ph 6.3 - 6.5. No runoff yet, so ph may be higher in soil. Lower ph and watering til runoff next time?

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Upper leaves are yellow and not smoothI noticed leaves on top are closing and today are yellowish. Older plant aren’t stretching more, I thought it’s too much light or too hot but it’s kinda weird because light are at 40cm from longer plant and 50 from smaller, temperature are max 26C. So, it’s normal?

Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flowerThe odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.

Is it time to feed nutrients now or can I wait?I have not given any nutrients yet but I'm wondering if I should.
1. Are these really signs of nutrient deficiencies?
2. Which nutrients are missing?
2.1. My guess is P, N and/or Mag, Cal. Is that a good guess?
3. Is BioGrow a good choice to address these deficiencies now?

Is this an Iron deficiency? The tops and new growth look too yellow and the veins are yellowing with a darker green in betweenHaven'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.
