Is this CalMag deficiency?
BetaVulgarisstarted grow question 4 years ago
Hi there! Are the pictures of my plants showing CalMag deficiency? The symptoms are located on the older leaves. My tap water contains 29,8 mg/l Ca and 1,93 mg/l Mg and I am not using a special CalMag fertilizer. Thank you! 😊

Looks like your on the right track try supplementing her with some cal mag. When using tap water it's almost a must. Also are you leaving your tap water out for 24 hrs to air out? What's your pH like? Leaving the water out for 24 hrs helps burp all the chemicals In the water out. Using an air stone in the water can speed up this process considerably! Cheers and happy growing!

ca and mg are two different things, and i don't think that looks like eithe rone.
both will have spots of some sort. Mg wil also have interveinal chlorosis. P and K tox can cause Ca/Mg deficiencesi.. it's complicated... lol.
you need to know whats in your fertilizer.. if it has 100+ elemetnal ppm of Ca, you don't need to add Ca. it exists in abundance and if ther eis a problem showing that, it's because of pH or lockout -- a far more common issue.
unless they leave it out, and if they do it's to make you buy more stuff beacues it is an essential element, you may need some... but, also you need to find a different brand, if that is the case.
google how to convert plant labels to ppm and go from there.. read your labels, make a spreadhseet.. know what you are giving you rplant or guessing about it will only cuase an infiinite and unending cavalcade of problems.

Leaf fade vs. deficiencyHey everyone, does this look like a deficiency? I’m in week 6 of flower, I had half a week of high temperatures and I’m sure she was affected just a bit and noticed Bud growth slowed slightly. Not sure that influenced this and if it’s a deficiency(magnesium?) or normal leaf fade.

Continuing calmag deficiencyWhat I think is a calmag deficiency started about 10 days ago. At first I thought it was too low PH (6.0 - 6.1), so I corrected that, but no luck. Then I started adding biobizz calmag, still no luck. It seems that the deficiencies are picking up speed again. Any ideas appreciated

Intervenial chlorosis, thick wrinkled leaves. Ph imbalance or quantity of nutes? Will adding CaliMag back in help? Trying to avoid burnt tips issueHard water (7) lowered to 5.8. Last week: 1 gal 3 waterings, w FloraGro (2.5 ml), Micro (2 ml), Bloom (2.5 ml/), Hydroguard (2 ml). Last grow had burnt tips and possible N deficiency, so I was trying to avoid that. This week I've switched to GHE's schedule and added CaliMag.
