I just past week two in flowering things start to change

vs7 · Jun 28, 2016

Hi everybody this is my second thread due to lack of information in the first one

i have a problem leaves start to burn from the tips then lower leaves start to turn yellow

i'm wondering is it lack of nutrients or over feeding

i'm in flowering day 15 i plant in a soil 5 gallons smart pot this is my first grow i'm using general organics feeding schedule

my last feeding before the problem was
5 ml bio thrive bloom
5 ml calmag
10 ml bioroot
2.5 ml bio bud

this is my temp and humidity

here some pics

Still a bit more info needed. What is your PH?

The Burnt tips would suggest nutrient burn. But the yellowing lower down could be a number of things. Could be its magnesium or Phosphorous deficiency. Post your PH.
I wouldn't be surprised if you had a number of problems going on at the same time but the question is why. Post the PH of your nutrient solution and the PH of your run off. folks may be a able to help a little more.
Also post a whole plant pic or a shot from further away, close ups are great but not always ideal to see the whole picture.

Edit, also tell us how often you are watering and with how much per pot

burnt tips yes but yellowing in the lower canopy is N def and lack of light

I think your problem is ph related. In soil you really have two options. Go straight organics or go straight salts. Both of these methods fuck with ph hard in ways you wouldn't think.

In organics you don't ph the water. The beneficial bacteria buffer the ph to the correct levels by using ions.

With salts you have to find your sweet spot which is really hard. Every soil is different and the only way to know is to check your run off. When your soil is breaking down it releases nutes that were in your soil which generally drops the ph.

Test your run off and see if your in the correct range. Testing the first 10% of the run off is key or you'll be testing the water you just put in as your basically flushing.

Yes it easier to tell from the full pic, which is why we like them ey. Close ups were a bit hard to judge and I wanted to make sure of the PH range. The input range is fine, does look like lack of N on the lower leaves.
PH run off will answer the question of other nutrient problems. The red stems were the first thing I noticed (could just be the strain)and the first pics looked like possible clawing but from that perspective it was hard to actually tell. From the full plant pic that doesn't seem the case.

I'm only into my 5th. grow but something similar happened to mine and I gave it a good 5 gal. ph'd water only flush and final gallon add 1/4 blooming fert and cal/mag. Work back up to normal feedings..

Your problem is that you switched to bloom nutes to early, a common mistake and your following a feedin schedule that your plants are unaware of

Don't start bloom nute till after week 3, week 4 or 5 would be better, if ya use boosters only use em once and learn how to read plants so you can get on their schedule

Good Luck

i waterd ph 6.5 the run of is 5.5 with 900 PPM

coreywebster · Jun 28, 2016

If your feeding/watering with 6.5 and run off is only 5.5 that would suggest your root zone could be as low as 4.5 which is way way off and will lock out most nutrients. I would of thought the solution In a standard non organic soil would be to flush with higher PH solution like 8, but since soil is not my bag and ph 8 is craziness I will refer to @RM3 who knows more than I about the subject for some clarification.

They need to be fed a bit of veg food, or grow food what ever your brand calls it with NO bloom food that will slow down the yellowing. The leaves that have turned are gone, if you keep feeding on some pre formed schedule you will continue to lose leaves

i swiched my lights 12/12 on the 13th of june

Just feed with not ph'ed water untill the run off ph rises and you'll be gravy. Soil growers use dolomite lime to offset the natural drop in ph. If i were you i'd just get some coco the next run as ph fluctuations are quite rare.

Edit I would just feed with flowering nutes, if your worried about the yellowing leaves just foliar feed with some nitrogen.
