Calcium issues with autos and calmag

Wolters_88 · Dec 5, 2020

Ok, so this is my third grow and once again I’m having the same issue. I can’t seem to not get a calcium deficiency. I put in 5ml of calmag per gallon with every single feed. The plants look great but it’s still happening. Attached are my girls just going into flower. Is there anything else I can add to help this issue?

Got an up close pictures of the affected leaves?
What medium? And what nutes are you using?

Beachwalker · Dec 5, 2020

Agree, need better pictures because I don't see a Calcium deficiency; recommend you describe what you're feeding, pH & PPM, frequency of feeding, medium Etc.

I’m using GH three part with 5ml of calmag per gallon in coco. I’m watering at 6.0-6.2 PH and I’m 7 weeks in on the oldest plant. I’m around 900 PPM.

Looks more like magnesium to me. Did it start on the older larger leaves?

Aqua Man · Dec 6, 2020

Adding more may help but could be from over watering, high humidity or combination. Did you change to flower nutes already?

Wow! The first thing I would do would be to check for mites with magnification

Do all the plants have that same marking?

Here's something new, what's this??

prtcleman · Dec 7, 2020

Oh my, never saw that. Gonna go over the plant with a mag lense. :(
Looks like a mini scorpion. Ugggg

Re: mites, looks like you've got a pretty bad infestation

Aqua Man · Dec 7, 2020

Take a pic further back, what lights and how high are they?

Looks like bug damage and light bleaching possibly.

prtcleman · Dec 7, 2020

T5 & 6-8 inches above,
Will take pic tonight. Thankyou all for the help so far

So nobody has any ideas what this could be?

prtcleman · Dec 8, 2020

Lights were 2-3 inches away first off, moved them further away. Took s backside of the leaf . & the mini scorpion was justa fly that died with resting on his back.

happynessistheway · Dec 8, 2020

i am no pro but except of maybe mites or other infestation i would consider a nute lockout before a shortage in the soil.
check ph of soil first some minerals are bedder solving in acidy some more in alkaline conditions
if all other conditions are good maybe some humic and fulvic acid could help with uptake if it is in the soil but needs help gettin in the plant.
just my 2cents love you all :)
right now i am thinking if i need to buy some cal mag too, but i am using tap water in europe dont know if it is sufficent or needs more.

I can see a thrip sucking on your leaf. Magnify the photo in the center and look for the orange cigar looking bug.

Homesteader · Dec 8, 2020

Sorry I can't circle the photo and show you but I see a few of them on the leaf. If you look at the black spots (shit) on the leaf in the center you can see a thrip right above it. There is one also on the opposite side of the center leaf. Thrips are a pain in the ass but not too hard to kill.

prtcleman · Dec 8, 2020

Thrips, well that’s a first!
I seen the little flys in the tent too. Maybe 3-5 of them. Killem when I see them but insecticidal spray bath is the first operation.
Thankyou boyz. This forum is so helpful to a person like me. I’m really greatful for all the replies.
I see the shitttt & the bugs. Oh my!!!
a buzz kill. :)
