Dear RIU ,

I'm growing in the sun, (my balcony) a few lowryders - well into the 2-3rd week of flowering.

Yesterday I noticed that some of the bigger leafs has started to show some brown spots.

I'm feeding them with BioBloom (NPK 2-6-3.5) 3-2 ml/l.
I flushed the pot today with just plain water, cause i'm thinking that maybe it's a nute burn of some sort, but i'm not sure.


Could it a be deficiency or burn? in any of the cases, what should i do to fix it?

Thank you all,
Dave

IS THAT ALL ????????
????? PLANT NEED MORE THAN THESE ...... No it not mg ! it look like need more nutes look at his npk ... i would add foxfarm grow big or advanced A&B SENEIS BLOOM ... BY THE WAY IF I WERE YOU I WOULDNT USE BIOBLOOM ... I WOULD USE THREE LIST FOXFARM IS OK BUT GOOD PRICES FOX FARM BEEN AROUND FOR YEARS
ADVANCED NUTES ARE THE BEST !! BUT MORE MONEY BUT I GET 300 % BETTER RESULT
GERENAL HYDROPONICS CAME OUT PRETTY GOOD ..... I HATE SEEING PEOPLE WASTING MONEY ON GOOD LIGHT AND HARD WORKING MAKE IT GROW RIGHT WITH SHITTY NUTES ... GOOD LUCK ...

Thanks for the reply!
I'm growing in soil, not hydro...
ANyways, I got "HESI" fertilizer with PK 8-4,
I didn't mention that I'm also using Biobizz - Top Max, BioHeaven....

I didn't use the HESI yet, cause I'm afraid it'd burn them...it sounds like a pretty strong shit.
Are you sure it's UNDER fertilizing?

Thanks ,
Dave

before you start adding more ferts to the soup, may I make a suggestion? I'm surprised that no one has considered a PH lock out, considering all of the ferts the poster is using. Before we go any further and possibly kill the plants, I recommend that you use some PH neutral water (7.0) and run it through the soil. Catch the run off water in another pan and then PH test it. I'm willing to bet my money on your soil PH being in the 5's and the run off in the low 6's. If so, you need to dillute some garden lime, about 1/2 tsp per gallon, and water it in after you have flushed the plants in 6.5-7.0 water.

Ur Welcome, make sure you do that before any other meddling with those plants. A lot of soils will go acidic after awhile and some lime is needed to bring the Ph back in line. Your goal is run off of 6.5 consistently. I even keep a calendar in my grow room and the plants are numbered. I write down the run off PH for EVERY watering or feeding for each plant. It is timely, however, if a plant looks sickly, I can get it's number and glance at the calendar and quickly determine of the plant has a PH problem or a nute problem.

I would assume he is referring to older growth when he writes "the bigger leaves"

Indeed I am, the older and upper leafs only.

It seems like a must thing to do... don't know how I didn't have a PH tester yet
