Is this cal mag deficiency?

Wondering if this is calmag def before I go hitting the soil with some dolomite? 70% sure it is

Looks like mag Def to me, i had the same last month and a bit of cal mag sorted it out.

Where I am, to get calmag I'd need it shipped in from murrica or wherever dolomite lime maybe?

R u in uk?

New Zealand, also is it normal that when I turn my light on until about 2 hours before it goes off the leaves are all reaching for the light but after about 10 hours of being on (2 hours before dark cycle) the leaves are almost drooping? Paranoia 101

yes don't panic

I already have dolomite lime or could buy a few KGS of Epsom salts for $5 would these be an effective cheap option instead?

yeah i just added that before you responded

Cool, and maybe mix dolomite through the soil of the other plants I have so I don't get this again you reckon?

Epsom is mag has no calcium . I am not a soil grower but u cld check this thread out mate

As an organic soil building grower......be careful adding Dolomite......Dolo is rather Mg heavy and can cause Mg tox......Easy fix is to mix it 50/50 with Dried crushed eggshells and mix that into your soil......Fast Ca fix? Use a coffee grinder and really powder some eggshells and let them soak in a bottle of water till needed.
Need it? Shake the bottle well and use a few Tbls in yer feed mix..

doc

I got told that you can use cal mag pills for humans in health shops and grind it into a fine powder......
don't quote me as never done this but the labels on both are the same. If anyone knows any different please tell.

Also cal and mag Def are mobile so it will show up on lower leaves, on mine stems went purplish.

What you need to do if you are not too far into flowering is foliar feed a calcium solution @2m/L once only and then feed base at recommended dosage after that.

I'm about a week and a half in but the buds are quite well formed
