Calcium deficiency, foliar spray during flower?

It is always good that you find out the source of the problem and next grow will be without these issues. But for now, at first you are definitely NOT 2,5/3 weeks to go, I would say at least 5-6 weeks when I see the buds (you are early flower). Its long way to go bro. Your soil is probably too acid for uptake Ca and Mg and other basic nuts, so when you now change your water source there will be almost no change and you will end up in total lockout. You have noticed soon thats good, so you need to raise your soil pH asap to save the plant for further 6 weeks untill she fully rippens. Do not believe the shits that breeder says, they are all liars. Go get some dolomite lime top dress the soil and mix it how much its possible and than water untill regular runoff. You need to neutralize the soil reaction otherwise you will be forced to harvest soon end your yield will be lowered and affected. If you can change your water source its good but do not expect the soil pH will rise up only by watering with RO water with calmag and pHed. Anyway, do not use dolomite lime and than calmaged RO water. Try calmag, when not help, than try lime, any messing! Good luck

Great thanks for your advice. I've ordered some calmag. So if I try this and it's doesn't help try lime?

I would do it opposite way, because dolomite lime provides that Ca and Mg also, but if calmag makes the job it will be for sure easier... I only doubt that calmag is good choice because your tap EC 1,1 has a lot of that stuff inside. Lime need some time to take effect so must be finest. What is your soil pH?

Also I know you've said the plant has another 6 weeks, but this is an autoflower that been growing for 10 weeks already. Will it go another 6 weeks? It's harvest time is supposed to be 11-13 weeks from what I've seen of other grows. If I try keeping it going for another 6 it won't herm?

You need to grow it until it’s finished not to a specific set of weeks or days.

the plant will tell you when it’s finished and not the Other way around.

That's why I thought I'd I used RO water and gave it calmag and whatever other nutrients the plants need and Ph'd it properly that would work? Last time I watered I did at at 7.2pH because I know my soil is too acidic and the run off cam out at 6.9ph. I'm not 100% sure what the soils pH is. The last time I watered (on the 1st July) I watered at 6.2 (because the Biobizz feeding sheet says to water around that for some reason) and the run off came out as 6.0. I've definitely been watering at too low a pH so I'm just watering with phd water at the moment at around 6.8, but I thought I'd raise it today just to give it some help.

Start to count when start flower. Than your soil pH is not too acid. Acid is when it drops to 6,0.
