Hi everyone, this plant is cream mandarine on day 37. These little marks on the leafs have popped up since yesterday, they can be seen from both sides of leaf. Iv not started on cal mag yet or any epsom salt, I wanted to actually await to see the deficiencies and try learn a little more So I'm hopingiI'm right with calcium def. She was fed water first 3 weeks then I planted 2 biotabs and plain water since. Temp 25 rh 35. I did foliar feed a couple days ago and maybe turned lights on a bit too quick but I don't think it's that. Hope someone can help.

That looks mg ish... I understand you wanting to see the deficiencies, but understand, you are not seeing NOW, you are seeing deficiencies from days to a week ago. Calcium is immobile, so once its parked it cant be relocated. Autos being on such a timetable don't give us much room for corrections.
 
I got two of them they doing brilliant on growth and they a lovely colour, but they both have got these spots on them, I must add the two forgotten cookies same age and slighty ahead on budding are not showing these and have been treated exactly the same. and I'm certain the marks

were not there yesterday or day before so they are only just showing but yeah I understand with cal and mag the deficiency started weeks ago.
 
Thanks namvet, so is that definitely calcium then? Water is at 7.4 and with biotabs it's water only so I have been feeding at that as didn't want to ph down. What's the best organic ph down then you would recommend although I'm not sure I have to as my soil is 6.2 and I water at 7.4 and my run of is 6.8. Its my first time using biotabs also.
 
It's hard to find organic ph down even on Amazon but if your using organic nutes you don't realy need to ph.You could use lemon juice for ph down if needed.
 
For an organic pH down I’ve switched to Apple Cider Vinegar that’s organic and still has the “mother” in it. The brand I use is “Braggs.” It has beneficial bacteria in it and will adjust your pH without any damage to your micro herd. In fact, it’ll ADD to your herd! In my RO water it takes 1.5ml of ACV to drop from 7.4ish to 6.4ish.

HTH
 
Hi everyone so iv been adding sensi cal mag xtra at 1ml per litre for a week now, still getting this spotting on leaves. Wondering if we still agree it's calcium deficiency? Any imput would be much appreciated thankyou. Also i think my flowering has slowed right down since i started adding it swear they done nothing in the past week.

That’s what it looks like to me.Are you still adding cal/mag with every watering?If not you should be.Cannabis is a calcium hog when she turns on to start budding full swing.It is something that is very hard to over do with the weed.
