Calcium def. right?

[Kinderfeld]

Got a problem child at the moment when everyone else seems contempt. My PH is 6.5 and they are in soil, around 40 day flower. I am sure this is calcium just need others to confirm usually my calcium def. are a bit more spotty...if you guys need more info I can give it, but I do have pics. Been trying to give it cal mag but it doesn't seem to be fixing the problem from spreading. It is spreading reeeaaal slow, only a couple leaves have the signs but they first appeared 30 days ago.

This is clacium def. right?

Are you using tap water or RO?

 

[Kinderfeld]

thanks for the reply weedhound.

I am using tap water, city water. comes out at about 30 ppm (very low I know, I use epsom salt to bring it to a 60-80 range, just water alone that is), and the PH comes out at 8.0.

I do want to say though I bubble my water/mix for at least 3 days usually 5-7 days before I water them and at that point it is neutral. I adjust the ph and ppm if it is a mix and not just water though so the runoff comes out at 6.5. I also added lime to the mix but their last transplant was a while ago.

I knew I had shitty water, does longer bubbling it hurt it? Sometimes it is bubbled for a week...

When you feed them plant food what do you use and how much? Look into a P or K def.

 

[Kinderfeld]

Yes yes...I thought it might me P , thanks legion

Actually their first feeding was about a week and half ago, their second last night. FFOF feeds them all the way up to the first 30 days of flower due to my transplant timings. But thins makes prefect sense... I feed with humic acid, PBP soil and either guano or big bloom which is basically guano. I only give 5ml of all those combined tops I have tendency to over feed. Thanks for the advice guys I will feed heavier and see what happens.

Actually I think you pinned it pretty well.....I would call your tap with with it's ppm of 30 too low in beneficial minerals etc. my hydro guy...who is VERY good....tells me he would use CalMag if the tap water were under about 100ppm (and ph were stable.....that was our issue with well water). Over 200 ppm he would start considering the water "hard" for hydro apps although I've seen some folks grow fine with tap water in the 300's. good decision to to with the CalMag. I definitely think that is your issue here.

Much of your damaged stuff will not recover, but new growth should be normal.

Good luck.
