Yeah, you've got a calcium deficiency going on here... I'm not familiar with your nutes but if there is a lot of nitrogen in them, this can cause calcium to be locked out and your plant can't absorb it. I would also suggest you lower your PH to 6.2 as this is the "sweet spot" for calcium absorbtion. If you think you've got a lot of nitrogen in your soil, you need to do a flush to clean out the nutes/salts that have accumulated adding in 1/2 nutes (but no nitrogen!) with the last gallon of water... If you know there's NOT a lot of nitrogen in your nutes, then adding some calmag may help (but only give this to the ladies once a week!). The damaged leaves will NOT recover but if you can get a handle on the problem, further damage will be avoided.
Good luck!

Please help. Last plant died exactly like this. Yellowing drying leaves from the bottom on all fan leaves while shoots get stunted / eventually affected.Transp recently from 1g > 5g. Seemed ok at first day after (no wat) then leaves started rapidly yellowing / drooping. Tent is fairly small 40x40x120. Could it be the heat ? Also took out humidifier but still in same room tent vents. Is Canna Pro Plus watered between 5.8-6.2 ph ?

Hey Guys, two or my plants seem to have a few yellow tips and some brown spots on the leaves. The problem is minor but I think it might be lacking Calcium? I think it needs some Cal Mag added to the next watering. Any advice would be appreciated. See pics. ThanksWeek 11

Some very little holes appear after feeding them, and maybe after I spray them with water. Could it be some light burn on the spots that some water bubbles had stay for long? Some nutrient burn? (I don't think so) I've searched for bugs and I think it is impossible, but no one knows when the little bastards want to show up... For now no signs of any kind of bugs... Maybe PH issues? I really don't know.Week 4

Issues with leaves. Day 90 total, 30 of flower. Leaves have been getting more and more yellow the past week, with progressively more brown tips.Vpd has been pretty close to ideal, the pot had 1 gallon less soil so could be missing out on some nutrients? Possibly Potassium? Otherwise not sure what it could be. Does not appear to be N deficiency because the leaves are affected from the top too. What should I do to fix this

(Mimosa auto in coco) Yellowing tips on new growthThe top of the plant (new growth) is showing some unhealthy signs.
The tips of the leaves are yellow and there are lighter green stripes on the leaves themselves.
I googled and the signs match to a number of deficiencies, but i lack the experience to diagnose correctly. Plz help

Early nite burn?Hello! I've noticed that many of my leaves have burnt tips. I first noticed this about 3-4 days ago. Since then, more leaves seem to have this but the it hasn't gotten worse on individual leaves. Could this be nute burn?
Thanks in advance!

Nutrient Burn?Too much N? Oldest leaves are affected generally although some younger leaves showed burnt tips. No obvious clawing. Temps have been somewhat lower lately around 25.
Fed twice @ 1ml/l of Biobizz fish mix.
Decided to flush with straight water just in case.
