Leaves turning yellow with spots

[mtam12]

I trimmed some leaves. I was also using just the part A of the fluroduo. I fed with A and B. Seems like it helped.

I've used nothing but FloraDuo. Used it in Soil, Coco Coir, and Hydro. It's great stuff in my opinion. If you run 50/50-A/B it's pretty much The Lucas Formula and will get you through veg, and flower.
You HAVE TO use part B also. (well, REALLY SHOULD)
Part A is not a stand alone nutrient. If you are supplementing soil mix in some B per the feeding schedule.
Liquid Koolbloom will double your yields if used per the feeding schedule. Don't skimp of Liquid Koolbloom. It will make a HUGE difference in yield.

You should have a feeding schedule, but if not here's one.


Since you've got good nutes why not transplant that girl to some coco coir and be done with it?

Thanks for the info! At this point I'm kinda nervous about transplanting. I'm sure the roots are all around the edge. I'd rather let these two go and get something than transplant and they die. Make sense or not? Does the plant on the left look right? Seems droopy? Normal? Both plants get identical treatment as far as watering, nutes, mite spray etc.

I would flush, give them a couple days, and wait for them to show signs that they want feed before feeding again.

Hey guys,

New plant, new issue.


Seems my plants picked up a deficiency. I thought it was nute burn but has spread to leaves that weren't present when the burn happened.

I can't decide if its a Phosphorous or potassium issue.

Please share your opinion on what you think it is and any advice on correction.

I'm using Flora duo A&B and cal mag currently for early growth stage.

Thanks


P.S. Could it be not enough water?? I am using that self water system.

Droopy leaves = too much water.

1) N, P, K, Mg and S are considered mobile: they can move up and down the plant in both xylem and phloem.
Deficiency appears on old leaves first.
2) Ca, Fe, Zn, Mo, B, Cu, Mn are considered immobile: they only move up the plant in the xylem.
Deficiency appears on new leaves first.
