Someone know what this is????

Ok let my start by saying thank you to everyone in this great community I have learned so much an been helped alot by people here. With that said.
My plant is scaring me lol
i started veg about 1 an a half weeks ago I can bee little buds coming an so many hairs it's so beautiful. Upon one of my hour training sessions I noticed a couple leads with brown spots on them. Some have no brown spots some had alot of brown spots. Well this was a couple days ago an it was only on 1 of 4 plants in the tent(4ftx 4ft)
An last night I saw a few on other plants. So if anyone has any suggestions please let me know. A little info on the grow. 4 plants under 350w mh & 600w Hps. 440 cmf fan for outtake. I use full set of cyco nutrients. The strains on plants are. Grape ape. Mothers finest. Bubba kush. And deisel I'm growing in coco grow with a 70/30 perlite mix.

If I didn't answer anything just ask.

Here are a couple pics to show you what I'm talkin about.












Thanks for looking. Any help is great thanks

calcium def

Did they get a transplant recently? What's the schedule for nutes, and what types are being used? Am also curious what's putting holes in the leaves unless you or someone else allowed in the room is being careless with pointed objects.

Well defo a Calcium deficiency. Would like to know how your Mother Finest turns out, Looking at getting some of those seeds from Sensiseeds, absolutely love my Sativa dominant ladies...

Agreed with this, as an early stage def - if it's progressive, it could be a few others but would start simple and work with the cal/mag and then focus on the holes in the leaves. Ensure your pH is proper as well so you're not getting cal def as a result of lockout instead.

This could be helpfull.

Wow that was quick. Thanks. What should I use to fix the problem and I'm using cyco nutes the whole line up. And I'm using a drip system that waters once a day for one minuet at a time. Ph is always around 5.6 - 5.8

Oh and tho is my second run at mothers funniest awsome strain btw

That chart is missing a few things.. namely.. exactly what the pics show... the start of necrosis based on Cal def - the chart says no go, those who grow say yes it's possible.

Cal/Mag .. or Cal/Mag w/iron (depending on the cal/mag mix you own, or wish to buy)

^^^ Precisely. I highly recommend Botanicare's Ca/Mg with Fe. I'm very happy with it. Further with cannabis if I don't supplement my (hard water) with Ca/Mg I get yellowing and punctate rust spots starting in the middle of the plant and working mostly downwards.

Agreed with this brand recommendation.. if you dont have cal/mag yet.. Botanicare is the best thing going that has Ca/Mg w/Fe in it

i just picked up GO cal mag the other day. il look for this one next time.
