Deficiency or PH?

[Kenster420]

My first photo grow, everything was going good until about a week ago lol. I flipped to 12/12 32 days ago. Day temp is 75-80f anf night is 66-69f. I started noticing 2 weeks ago purpling when my temps hit low 60s. So i got a heater to run at 68. Its very well possible my cheap PH pen is wrong. I was doing all organic top dress going in to flower. Started adding dyna gro bloom 28 days ago and just last week Signal from TPS. Haven't fed calmag for 2 weeks. So i fed calmag, kelp, and recharge just now at 6.8. My run off on purple plant was 1500ppm other one was 640ppm. Im in ocean forest for both. Other one has maybe 2 gal of peatmoss when i transplant in to the 5 gal. Im waiting on an Apera Ph pen and will know the truth on my PH. Quite honestly ive only been watering until the slightest run off. Only get .35 to .75 gal every 2 or 3 days. Does anyone have any ideas based off experience? Im completely lost haha. One of my other plants is doing just fine.

Doesn't look too terrible...my guess would be overfeeding. Whats your soil?

Just my humble thoughts... I would keep feeding just water for now... If grow organic on soil, you need to rely on microbes to do the work. Bottle nutrients even, if It says"organic" still. affects the microbiology in the soil, thus disturbing the whole.process... But, there might be some overfeed too...

Potassium deficiency.

As stated by @hotrodharley … potassium is the main issue … toss Signal crap . Its a bottled “ sweetener “ that does nothing.

Doesn’t sound like you are running dynagro bloom as needed if you used only 28 days ago. Cuz technically you can run this alone with that medium as main bloom feed ( weekly ). Potassium is deficient ( serrated edge yellow and tip browning ) will always mimic nute burn. Purpling is from temps which also reduces uptake.

Pics of small lower leaf getting spent is fairly typical as plant PULLS what it needs from itself.

Keep shit simple ….

How simple ? You could “ recharge “ that medium by adding MORE FFOF ( ocean forest ) to top dress alone . It can be even bagged and steeped as a tea for a simple soil drench feed. All of your issues are from your feeding habits and throwing too much at it.

If you add to much Magnesium you'll get potassium deficiency and visa versa. These two elements compete for uptake. If you're using Cal/Mag as an additive you should stop and just give it water for a while.

Ah welcome to the club. I've been having this same issue in FFOF for my last few runs. I've finally just now learned that it's ok to step back and stop adding the calmag and nutes etc everyone says to use. If you transplant properly in OF, you shouldn't even need any bloom nutes until a few weeks into flower. My suggestion is lay off the PH down etc, just use regular tap water or RO if you have it.

That's good advice, FFOF is an organic soil that rely on microbes to break down organic matter into chelated nutrients. These same microbes act as a buffer and balance the ph keeping it where it needs to be. Since plants rely on a fluctuating ph to uptake nutrients the microbes change the ph according to the plants needs in order for the plant to produce more sugars that in turn feed the microbes who then feed the plants.

Ive noticed with all the advances in technology everyone now wants to treat their plants like a racecar, including myself. Probably just a youngin thing. But I'm finally seeing the bigger picture now, after throwing too much crap at my plants the last few runs and seeing how unhappy they were .

Hahah i am my own enemy! Will definitely adjust, i fell victim to nutrient marketing lol. I really did start getting problems when i complicated how much of what to add.

Yeah its very tempting to add more for instant gratification. But we definitely pay for the soil. May as well let it do what its supposed to do. I still have dry amendment i topped dressed 5 weeks ago too. So ill just water molasses and kelp ph to 6.5

Appreciate all the input, glad i got on here!
