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😉

Deficiencies at Day 60 or natural, expected fade?Does my girl look like she is suffering from a deficiency or is it a normal fade for day 60 since sprouting? What can I do as she definitely has a while to finish I feel? Any estimates on how much longer she has before getting close to chop? See most recent comment for details.5 years ago

Small yellow/brown spots. Rest of plant looks fine. 5 days into VegAbout 5 days into veg. 7 gal smart pots. RO water. No Nutes in the water so far. When transplanted I added a teaspoon of root microbes. Everything looks good and the green looks lively. Issue is there are few and subtle yellow spots. Not crowding. 1 or two on random plants.

Yellowing/ leaves dyingBeginning of week 4 flower and my girl is losing bottom leaves faster than I’ve ever seen. They are yellowing and falling off quicker than I think is healthy. However I also have burnt tips so it shouldn’t be due to underfeed. Rootbound maybe? Let me know

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?5 years ago

Yellowing on GT and clawing on CBI'm seeing an issue with Ghost Toof. The lower leaves are burning it seems. It looks like it could be a K(Potassium) issue, or possibly nutrient burn.
Also, Chem Bear seems to claw quite a bit. I don't think I'm overwatering... so maybe a Nitrogen issue?5 years ago
