Yellow spots on leaves. Need help

You have to cut your PPM!
Make sure your runoff is 5.8 or so
Cut any calmag now! Calcium is causing this.
Feed at 200ppm or so, and 5.8.Ph. Flush it through!
MAKE SURE YOUR RUNOFF READS THE SAME!
Let us all know soon.

Hey, do you think 200 ppm would be sufficient for a week 4 autoflower? I have attached a picture below. Flushed and brought the ph down to 6.3. Will do another flush and try and bring it down to 5.8-6. Plant height is about 6.5 inches and is quite bushy.

It should be ok at this stage
You need to buffer your media back to normal.
You need a FLUSH!
Check the runoff too. Ph and ppm.
Dont be lazy!!

Yes, absolutely. Gave it a good flush today with ph 5.8 and the runoff was about 6.3 - 6.4. Its pretty easy to bring down the PPM but I always face a problem with Ph. Is that normal?

Thanks a lot, cheers :)

No worries
Do you have hard water? Or are you using calmag?
That ph is too high!!!
Calcium is a SWEETENER.
Probably why youre high.
Take some cal AND mag out.
Flush it.
Check your runoff.
Done.
Good luck

No. I use RO water and that's the reason I was using cal-mag. When do you suggest I should start using it back?
Thanks a lot, Cheers

Try half doses once you know the ppm / ph run off and such is ok. Gradually increase it while keeping the pH in check :-{)

Just go by your ppm and runoff.
You need to have an idea of the ph swing.
Ph high- calcium toxicity
Ph low- magnesium toxicity
Just check your ppm vs ph. Itll give you a REALLY good idea about your rootzone.
Reason i say not to use calmag is, calcium needs magnesium, and vice versa, in almost equal parts. Nitrogen needs both!!
Just think of 2-0-0 calmag :wink:
You need to find out which of the three is causing your issue.
Also whether you have lockout or deficiency!!
Good luck

FANTASTIC MATE :bigjoint::bigjoint:

New question, if nobody minds I post here. So here we go.. thismorning was a feed day, I was going to give the girls their first and possibly only dose of grow big since I'll be going into flowering soon. Well ( i mix my water at night so it hits room temp by morning) I noticed it took a shit ton of ph down to get my nutes to read 6.3 so out of curiosity I double checked my ph pen with some GH liquid solution, and my water was in the low 4s... so thismorning I woke up and calibrated my pen.. fixed everything and went to water, mind you this is day 3 between waterings, and the big girl is still wet and looking over watered. Now it' been 35 days, and these fabric pots have been bone dry by the 2nd day, ive been waiting 3 to be safe.. would my ph being so low cause the plants to not take up water? Should I flush the soil with accurate phd water? Or can i just wait until they dry and go back to normal schedual, maybe add a 4th day to the dry cycle?

Id, flush it with some ph'd feed solution. They'll droop right down, when ph is low.
Damn some ph pens, bro.
If im right, white vinegar, has a ph of 3....
But each point down is 10 times the acidity. Works in the other direction too.
