Happy Halloween!!:-P
I hope everyone has a wonderful weekend.

Can you give me some Ph advise please?

I grow hydroponically and have noticed unusual leaf spots on the Chemdawg plant I have now at day 31 flowering. These spots started a while ago and are not letting up.

I am using the same protocol and nutrient I always use and have never had this problem before.

I have added cal mag supplement, which I usually don’t add ,to see if it would help but it has not.

My Ph is at 5.1 (my ph pen is calibrated correctly) when I add the new food.

after about 5 hours of circulating in her bucket the ph reading went up to 5.4.

Could this leaf problem be linked to Low ph? Would you add a ph up ingredient ?

the local Lowe’s has organic lime for $5. I read baking soda works to raise Ph but is not very stable or I could drive an hour away to get some Ph up.

Thank you,

Amber

Got a pic of a leaf showing the spots?
i grew in straight nutrient solution for years. All kinds of different setups. One thing I always ran at was ph 5.8-6.1ish and an EC at around 1.6-1.7 for most of the grow. A little less in the beginning and also less towards the end.
If you got a complete nutrient, I would shoot for the numbers i mentioned and go from there.

My first guess would be Ca deficiency/lockout.
Do you know what EC or ppm they’re being fed?
I have been using the same products for 10 years. I use Flora Nova Bloom. It has ph buffers but It’s this particular plant that is so finicky . I guess I will play it safe and drive to the city and get the Ph up.
thanks for helping me figure it out.

I’ve rocked the floranova bloom on and off ever since it came out. EC of around 1.6-1.8 ph 5.8-6.1 and the only problems are usually from a Ca deficiency on certain strains from my experience with it. Sometimes an Mg.

I have Been adding 5 ml per gallon of cal mag and it didn’t help at all. So i figure it has to be getting locked out. Thanks for your time.

How often do you flush? I would flush and res change every 2 weeks.
When I was running hydro, I used floranova bloom. I added 5ml/gal, of cal mag.
I noticed everything was very reactive to ph imbalances. If I checked my ph daily, my plants thrived. The nice thing about hydro, is you can fix things quickly.

Oh shoot. That’s allot of calmag for sure.

btw, 1.6-1.8EC with the Floaranova bloom or grow is about 4ml/gal. Really curious what strength you’re rockin with it. To low/not enough Ca, Too much/lockout.
Hi! I always check my PPM balance with each gallon and check the PPM run off to keep her balanced and give just what she is asking for.
