Hello everyone, was wondering what this might be. Some of my fan leaves are developing a spotty discoloration. Some leaves more than others, some not at all. The plant is a Bruce Banner auto, nine weeks since planting, has been in flower for a good three-four weeks now. Growing in ProMix with Fix Farm nutrients. Thanks!!!

Thank you! Any specific product you might recommend? I just ordered this which contains some cal mag, but maybe not enough?

reefertilizer.com

Reefertilizer - Bloom Fertilizer

Our Bloom fertilizer is the final step of our fertilizer and nutrients program designed for Flowering plants. It contains higher levels of phosphorus and calcium.

I've been using the Fox Farm trio of nutrients.

0B7DC45A 49E7 49F8 82C5 3CA13EA0B0E1


Last week's watering I skipped the "Grow Big" (6-4-4) and only used the Big Bloom (0-.5-.7) and Tiger Bloom (2-8-4)

These are the labels for each, I've stopped using the "Grow Big":
4275634B E66B 4BD2 A5CE A242EE30F8C1


Use these two when I watered last week:

B0C8FB3A 79ED 4425 80E5 0FEDBABEFF3F


6C552ABF 9224 4527 8BC1 5BC906DE4572


Hopefully the stuff I just ordered does the trick, due for a watering tomorrow.

G is 100% correct here / I want to add that it’s an auto flower and you could possibly lock out the cal. With over feeding other nutes ? Leaves look pretty green and glossy and they are clawing at the end tellls me you are probably over feeding ? Also your water source ? U using tap?

Are you using at 100% recommended dosage? If so cut to mayb 1/2

Now they did change my water content awhile back and I had to adjust - so don’t think it’s perfect - old growth new growth after adjustment.

I guess I should call up the local water board and find out what their analysis is saying. When I did a preliminary test on the water with my pen it was showing 20ppm. I just assumed it was essentially devoid of any real measureable minerals so cal/mag to the rescue!!!🙂

Using delicious NYC tap water which I let sit out for 24hrs in a plastic gallon jug to dechlorinate before watering.

Yes, using 100% recommended dosages from the label. Three gallon fabric pot, when I water it takes about 3 quarts to saturate the medium. The instructions from the breeder said that it liked heavy feeding once in flower... Which is why I gave her full dosage last two waterings. I'll scale it back a bit when I water tomorrow.

Another solution....actual Cal/Mag!

lol, thank you! I bought the other stuff before getting my diagnosis, thankfully it had some too! Will also check this out.

i use the trio and almost never end up using full strength because for me will it usually burn them pretty well. those dosage amounts IMO are completely to make sure nutes are used more casually than needed to make you buy more.

on my photos i usually stop at 1/2-3/4 the listed amount on the bottles.

only thing i ever run out of or close to by end of grow is silica which i don't buy from FF ironically.

Should have the P-K and Cal Mag tomorrow, which is when I was due for a watering anyway. Should skip the FoxFarm altogether? Or continue using it, maybe reducing the dosage?

Thanks again everyone 🙏
