What deficiency is this ?
LetsGrooowstarted grow question 3 years ago
Anyone know what deficiency this is? All 3 plants that are flowering have the same issue. Seems to be interveinal chlorosis that is starting from new leaves at top going down. They are 40 days old.

They say that when you get a deficiency at the beginning of flower, it could be a potassium deficiency. That usually affects older leaves first though. Is your light too close? Cuz yellowing tips can be light burn. Light burn and potassium deficiency look a lot alike. Hope that helped.

They may need extra cal-mag from now on. I noticed mine had the same issue when started to flower. Also in early flower you can still feed them with grow nutrients to make sure they still have nitrogen to develop.

You may have cut out the nitrogen to quickly. They still need some at the start of flower.

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?

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.

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?

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.

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?

Is the plant just maturing or something else?I don't think this auto CBD plant has long to go. It's at 59 days of a supposed 65.
I just started to notice a some tips beginning to discolour and a couple of fan leaves have small yellow spots appearing.
Is this just the plant ageing?
