help with Calcium deffciency

[coas2]

Hi Guys,

I Am experiencing some sort of problem with a few of my plants and was hoping some people here with more experience would perhaps be able to help. I have some OG Kush which are absolutely fine and doing so well. I also have some blueberries that have the exact same environment and feed that are starting to show a few problems. They seem to be a lot more temperamental

The plants are about 5 weeks old now in there Veg and showing some brown rust like spots appearing. Some forming in the middle area of the leaves and some on the edges.

The plants are about 5 weeks old now in there Veg and showing some brown rust like spots appearing. Some forming in the middle area of the leaves and some on the edges. I thought at first it could be nute burn as i saw it appear on the tips but it seems to be appearing on more leaves and in both the centrals areas and edges. It is starting off as rusty like brown spots appearing and is starting to show on more of the leaves. I have a couple of blueberries and all of them are starting to show signs of it. The OG Kush however do not and both have been getting the same feed and conditions etc.

I am growing in Coco in 6 Litre air pots. Temps are a steady 80-82F although as it got cold and i pout the heater on before bed it has risen to about 91F for a few hours at its highest. When lights are out it drops to around 72F. Humidity around 40%. Has been as low as 35% and high as 56%
Have been giving around 5.8-59 PH and calibrate my PH pen weekly.

Any advice would be most appreciated.

Thank you

After some advice I flushed my plants and gave them normal feed with cal/mag added and phed to 5.7. I am growing in Coco.

It seemed from the best i could tell that the problem slowed or even stopped, however 3 days ago i finally switched to flower and the calcium problem has started to become worse. I have been adding cal/mag to there normal feed every time they needed a feed. They have probably had 3 feeds with cal/mag added over the past week. I know that the pH is correct as i recently just calibrated my pen.

Any ideas on what could be the problem? Its my first grow so I am not use to seeing or dealing with these problems. The only thing i can be left thinking is that my water quality is pretty bad. I do have some OG kush in same conditions, same water etc that are doing perfectly fine. But it seems these blueberries are pretty fussy.

I have bought a brita filter in case the problem is with the water. But was wondering if there could be something else i am missing.

Am also starting to wonder now if I have given them to much cal/mag over the past few days and overdosed them. How would i fix if this was the case?

Thanks for any advice.!

What I'm seeing is not a calcium deficiency. Calcium deficiencies show as very small rust colored spots all over the leaves. Those large brown areas along the edges are usually a lack of phosphorus. It could be caused by a lack of P or a nutrient lockout situation. Before adding any more, check the pH of your run off first. If your pH is out, then it's a lockout and adding more won't help and could actually make it worse.[FONT=Arial, Helvetica, sans-serif][FONT=Arial, Helvetica, sans-serif]Phosphorus[/FONT][/FONT][FONT=Arial, Helvetica, sans-serif][FONT=Arial, Helvetica, sans-serif][FONT=Arial, Helvetica, sans-serif]Phosphorus[/FONT][/FONT][/FONT][FONT=Arial, Helvetica, sans-serif][FONT=Arial, Helvetica, sans-serif][FONT=Arial, Helvetica, sans-serif][FONT=Arial, Helvetica, sans-serif]Phosphorusvp[/FONT][/FONT][/FONT]Phosphorus[/FONT][FONT=Arial, Helvetica, sans-serif]Pho[/FONT][FONT=Arial, Helvetica, sans-serif][FONT=Arial, Helvetica, sans-serif]Phosphorus[/FONT]sphorus[/FONT][FONT=Arial, Helvetica, sans-serif]Phosphorus[/FONT][FONT=Arial, Helvetica, sans-serif][/FONT]

id have to agree with lockout being the issue

blueberry is very nute sensitive and og kush is not , what would be really pushing the limits with the og would quickly fry the bb

pure ph'd water for a couple watering then 1/4 strength feed would be what id try

best of luck and peace :Cool:

I am starting to get small rust spots appearing on the leaves which makes me think is it a calcium deff. Will post some more pictures soon of how the problem has spread.

Just pure Phed water for a few watering sessions.?

If it is a lockout situation what would i do to fix?

It def looks like you are lacking P and from my expeirence with coco cal mag is a must.
