Lower leaves looking like this on multiple plants
TheUk420Showanswered grow question 3 years ago
Yup thats a typical Nitrogen Defiancy and it happens to alot of growers in the first few weeks of flower for some reason they hear that flowering plants dont need nitrogen or alot seem to think they dont need alot when in flower. This is false Nitrogen is a mobile nutrient within the plant meaning like P and K its in constant use by the plant and needed in every stage other than flushing of course and some will even argue that. Just up her grow feed and she should shed the leaves that are already yellow as she has already consumed them and most prob pump out one new fresh set before she starts concentrating solely on buds :) Though best of luck my friend doing a great job so far :) 👊

I would say mobile nutrients as Calcium, Magnesium, and of course everyone forgets about Iron! If you are growing in Coco I highly suggest you foliar spray right before the lights go out. I use Advanced Nutrients Cal Mag cause it contains Iron and Nitrogen also! Should correct any deficiency related to those 4 nutrients.

Also if it is nitrogen def you will see this start at the bottom not the top since its a mobile nutrient.

Where was this leaf from? Its hard to tell with just a leaf picture. Do you have any brown spotting mid-lower plant. I see the top leaves have the same look, The leaf tips in your other pictures look burnt which is usually a sign of to much nutrients. I would say its either to much P and K( phosphorous and/or potassium ) or a lack of magnesium or zink. Im leaning towards to much as your bloom looks a little high.
Happy Growing

It seems to BE lacking som nitrogen, increase EC with it. I think it's too early for those multiple Yellow leafs, unless you have there a super fast runner, although it is expected on last weeks of flora.
No expert here, my last grow getting Yellow too, but just a handful of days remaining to chop😉

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?

Slight lightburn?First pair leaves on left plant turn slightly lighter, first sign of yellowing a bit. Also I think they are a bit in a V/praying shape.
2 full weeks old under 75% of 200W leds about +-45cm. Should I dim them a bit more/hang higher?
Other suggestions maybe?

Yellow Leaf Tips with Brown Spots – What Could This Be?One of my plants has yellowing tips on some of its leaves, and there are also brown spots forming on these yellow areas.
Any ideas on what could be causing this? Could it be a nutrient issue, or is it maybe related to pests or environmental factors?

Sligthtly Yellow LeavesI'm growing 2 Mephisto Canna Cheese seeds. Canna #1 is looking very healthy and green. Canna #2 is healthy (ish) but its branches are more spread out and the leaves are a bit yellow green. I'm trying to figure out if I have a problem with Canna #2 before it gets worse.

Should I cut off yellow leaves?Bulldog cookies, 5-6 weeks in flowering. The leaves started yellowing, not fast like a disease or something. I'm thinking about cutting them off. should I? Would it be better for bud development, or in this flowering stage is would be too much stress?

Yellow Spots on Lower Leaves in Week 5 of Flowering – Nitrogen Deficiency?Hey friends, I have a problem with yellow spots on the lower leaves. People are saying it's nitrogen deficiency. It's currently week 5 of flowering, and I'm wondering if this is within normal limits and if I should just leave it as it is. Any advice on what to do?
