Is there someone out there that can help me figure out what is wrong with my plants? I’m growing in a ebb and flow bucket system, with an se600 Hortilux CHPS, and 25 gallon res. I’m currently finishing week 5 and the plants are expected to go to week 7 or 8.

Nutrients:
CalMag
Aurora Bloom
Aurora Big Swell
Aurora Infinity
M.O.A.B
Terpinator
Budswell

Those plants look mostly healthy except for the burning.


What is the EC of your rez?
What is the pH of your rez?


I'm not a hydro guy but somebody will eventually stop by that is.

The brown spotting looks a bit like calcium deficiency, only a little different? I've zero experience with what you're using for nutes, I'm a basic NPK/Micro and Fulvic kinda guy and haven't seen this . Maybe a touch overfed for my liking in flower, but very nice indeed.

I've heard tip burning like this is zinc deficiency related, but have not looked it up. With 3'ish weeks left, I'd already be dropping the nute levels and beginning the fade. If you're looking for the tastiest 'cannabis flavors' product, I would feed lightly the next week (base nutrients only, none of the other bottles), then plain water for the last two.

Looks like way too many nutes being used, burning them bad. What ppm are you feeding?

Hey what's up Dunn ? It looks like it could be a few things. First thing I would do is look for bugs under your leaves.
Then I would flush with just water for 1 hour, then again for 1 hour.
Then change your res. again with just water for 2 days.
Then after 2 days come back with just a 1/4 of the nutes you were using. And stay at a 1/4 for a week and see what happens. Also are you using a ph meter ? What do your roots look like ? GOOD LUCK BRO. And keep us posted.

At the end of the week the res has an
EC of 2.4
PPM is 1240
PH is always between 5.5 and 6.5.

Thank you for all the help. I’m draining the res right now and I’m going to flush the Lines and the brain bucket. The I plan on backing off on the nutes. We will see what happens. I’ll let everyone know. Thank you again.

Also, this condition is only on maybe 5% of each plant and only on the top new growth.

Hydro is like supercharging an engine. Max EC @ 1.5 on a 600 scale

IMO too many flowering boosters

I would flush them for a couple of days, then ease into the nutes at 500-700 ppm.

I am not an expert but the lack of yellowing makes it look like too much food.

Thanks everyone. I dropped the M.O.A.B which is a bloom booster that is 0-52-32. Then I put the primary nutes at half strength. The budswell and terpinator I left at normal strength because they won’t burn the plants. I think it was the M.O.A.B that burnt the plants. I clipped the dead leaves and we will see what happens. The current PPM is 610 and an EC of 1.2.
