PH Of Soil Is 7.5

Learn to do it without ph and you shall reap more in the long term.

This industry is flushed with additives calmag benies ph etc etc, since when did one bottle of ferts and a bag of soil stop working.

My ferts has cal and mag in, most do i just wouldnt add more. Good water is better than adjusting bad :-)
I've noticed that many dry ferts do not have any calcium -- probably because it attracts moisture.

OP is using Fox Farms bottles and I think they have enough cal-mag if he runs the full line.
BTW @CriticalJack18 when it's time to buy more nutrients, I highly recommend checking out megacrop by greenleaf nutrients.
It's cheaper, better, and easier to use because it is complete.

I ran the sample pack on a few plants in veg and they loved it. When I run out of what I'm using now, I'm switching to megacrop.

Ok thanks for the heads up. That’s Nute Burn right?

It sure looks like nute burn.
When did it happen?
I ask because it looks like you've got a nice fade going right now, so if the tips got burnt by nitrogen, it happened a while ago.
Last week when I started with just 1/8th dosage of nutes. I did a flush yesterday with lower ph. You think I should start up with some nutes and cal mag again next watering? Or does it look that bad?

Follow the schedule provided by Fox Farms. It should be a no-brainer.
You've gotta feed em when they're flowering.

I'd worry more about overwatering than overfeeding.
Overwatering can cause PH problems and eventually root rot. It also attracts bugs...

I don’t use fox farms. Everytime I feed tips burn and leaves are yellowing

Should I water/feed with a lower ph to balance it out?

Follow the directions on whatever you are using. The dosage they give is for a full week. If your plants dry out before it's time to feed again, just give them plain water.

Burn will never heal, so don't expect the tips to turn green.

I don’t even care anymore I’m gonna give them a small dosage of cal mag and nutes next every other watering and push till harvest. They need to eat. Will cal mag hurt my plant?

Finally found the good old ignore button! Well work comes early. I wanna see some pics here soon of the criticals. Good luck!
My friend gave me some cal mag. I am going to make a mix. I’ll probably do 1/2tspn of cal mag and 1/4tspn or bloom nutes. How does that sound for a mix?

i agree with this. you'll figure it out. they are mature plants and they do need to eat.

my 2c:

I think the burnt tips on your plant look the same in the most recent picture as they do in the picture you posted on saturday. they are not gonna heal. don't try to heal them. just pay attention to the new growth. rather than deal with teaspoons and stuff you should get a $15 TDS meter off amazon and feed your plants based on PPM.
"Seedlings, Early Sprouts 100 to 250
Early Vegging 300 to 400
Full Vegetation 450 to 700
Early Blooming 750 to 950
Full Mature Blooms 1000 to 1600
-Roseman ~2009"
Get the TDS meter. test your tap water. if its over 200 ppm, use filtered/distilled water and add cal-mag. if its under 200ppm you're probably fine to use tap water and not add cal-mag. add your base nutes to reach your desired PPM. pH to 5.8-6.8. It doesn't have to be perfect as long as it's somewhere in that range.

Ok thanks man. Great info. Just ordered one. How do i test it? Pour some water into a cup and stick the meter in? Then mix the nutes in a gallon and do the same thing? I’m 7 weeks into my auto flower grow what should my ppm be?

yeah you wont need to calibrate it or anything. it will come with directions. you pretty much just stick the electrode on the tip into the water and it will instantly tell you the ppm. you can monitor it as you add your nutes. I would say that you'd want a PPM of somewhere around 750, as you're in the "early blooming" phase.

Cool thanks man it should be here Friday. Is it fine to mix cal mag and nutes?

CriticalJack18 is either a troll or incapable of reading directions.
He latches onto anyone who responds, then pummels them with really dumb questions.
Example: "will cal mag hurt my plant" :dunce:
