WTH? Is this leaf septoria? Nute burn? It’s one plant of 3.
I’ve had other problems with nutrient burn, dunno why. I haven’t gone too strong on them, but now I’m down to no nutes for several waterings.
(These plants are around 7 weeks, OG Kush autoflower. NUTES: Big Bloom, Grow Big, and Tiger Bloom, per the instructions, every other watering. Temp around 75 degress, aroun d 50% humidity.)
No spray. Just watering every 2-3 days, as needed. As I said, nutes on hold, but it’s Big Bloom, Grow Big, and Tiger Bloom, as per their schedule.
I had noticed some small leaftip burning across all plants before, which boggles, because the nutes were on schedule and on recommendation.
Medium is Fox Farms Happy Frog.
@noddykitty1 What’s your thoughts on this one. At first glance it appears to be a deficiency, he’s stating that he has actually overfed before and burnt the tips but upon second glance the leaves at the bottom that are yellow look similar to some I had outdoor that had some type of fungus caused by low cal and mag issues that caused similar brown spotting.
Are you feeding or watering to liberal run off and following the FF recommended flush? FF nutrients are heavy in salts and can easily accumulate in the root zone crashing the PH and driving up the PPMs. Do you have any recent run off numbers
I do believe this to be calcium deficiency and possibly some other micro nutrients.
Fox farm trio is notorious for “cal-mag” deficiency as it doesn’t have any.
General Hydroponics Flora series is a “trio” that does have calcium and other micro nutrients.
As well as General hydroponics maxi series.
Im not suggesting you change it up now, just something to think about when its time to buy more nutrients in the future
I use General Hydroponics exclusively, both the trio and maxi series and it’s the smoothest most easiest grows ever…
Here my current grow if ya want to check it out, theres others under my profile if ya search through my posts.
It can be alot but once you get it, it can be very easy.
I work ridiculous hours in the summer so I’ve had to find the absolute most easy ways to do things and the GH Flora series (liquid trio) is great but the Maxi series is a 1 part powered, Maxi-gro for veg and Maxi-bloom for bloom.
Both have everything needed so I almost never have any nutrient issues and grow some nice plants.
The Maxi Series is my favorite, the 16lb containers last for many grows.
