Hi people,

**UPDATE AND NEW PICS ON SECOND PAGE **

It has been a very long time since I’ve posted.Hope everyone is good.

just started back up again and I’m running into a few problems about 3 weeks into flowering

a few of my plants are starting to display yellow leaves and are fading to a light green. Mainly on my orange diesel and 3 bears og. Also on the og, leaf edges are going yellow. And today I noticed that I have some rust spots on my forum stompers and sour livers.

I’m not to sure what the problem is? I’ve been scouring the internet but can’t seem to find the definite problem.
I thought maybe nitrogen but I’ve been feeding fish mix by bio bizz at about 2 ml a litre and upped it to 3ml last watering just in case but can’t see any change. I also added atiny bit of cal mag bio bizz just in case for the rust spots. But to be honest itnow looks worse.

Orange diesel, forum stomper, 2 bears og, sour livers
room temp 23-29c
RH 40-55
Light distance 17-22 inches
soil bio bizz light mix
Nutrient line bio bizz grow and bloom at 3ml and 4 ml a litre. Guanokalong taste enhancer and I added pk 4/8 By plant magic old timers at 1ml a litre about a week ago for 2 waterings running. I have now cut it out thinking it could be the problem but nothing has changed
I haven’t PHed as I’ve been told by many many people you don’t need to with organic. But am seriously contemplating it as I have no idea what the problem is.
I’ve got a full line of nutes and everything else seems spot on.
Anyway. I hope you managed to read it all. Any help is much appreciated.
Thanks

Ph check really works mate.it is not so bad.
 
On soil i dont know.but they sell ph testers for soil.is a divise you stick in tge pot(i dont know how accurate it is,never used it.my solution is 6.3 ph.now for first time i use canna terra seedmix soil for seedlings wich is 5.8 and i added humus de lobriz (ph7.1 i think) 3-4 lt to 25 lt of soil.it sucks a lot of water but the growth looks great till now
 
It looks like a pH issue of some sort. They look N deprived to me due to a pH lockout. Test your pH and adjust accordingly
Sorry took so long

plants seem to be getting worse. I checked my ph at and it’s between 6.8 and 7

I’ve been told more than once there is no need to ph in full organics??

Not true. If you have your soil amendmend correctly yes you can get it dialed in. Quick question. Is your soil pH 6.8 to 7.0 or is that your water pH after mixing nutes? Also if it is your soil pH how are you testing it

6.8-7 ph is too high for a feed. If that's your soils ph, then it's fine. What you were told about growing organically is partially correct. You do not need to ph when you are growing with a "living" soil. The soil must be alive and active. Technically you are growing organic. But you are "using organic bottled nutrients".. So your soil isn't "alive".. Which is a little different than growing organically. Almost every nutrient that comes from a bottle should be ph'd prior to adding it to the soil. Organic growers don't usually use bottled nutrients, they let the soil do all the work. Organic soils are usually alive with microbes, fungi, bacteria, and well amended. When your soil is "alive" the ph is controlled by the rhizosphere. After about 5-6 grows in the same pot and soil, my soil is now active and alive. I haven't ph'd or used any bottled nutrients in any of those grows. Not a single discolored leaf from seed to harvest.

Deficiencies do not automatically mean "add more".. 9 times out of 10, they mean the opposite.. One of two things is happening.. Either a ph lockout.. Which happens when the ph in the container/medium is out of range.. Or it's a nutrient lock out, which happens when there is too much of one or more nutrients.
In both cases, the "lock out" will prevent the plant from being able to use the needed nutrients even though the nutrients are present. For example.. You thought it may be a nitrogen deficiency.. But you are feeding with bio bizz grow and bloom, which both have more than enough nitrogen. So you know N is in the medium, but the plants don't seem to be able to feed on it. That's your first lockout clue. If you know you are feeding a certain nutrient, and that nutrient is looking deficient on the plant, that's a sign of possible lock out. Take a look at this chart and see how easy it is to get a nutrient lock out. If there is too much of just one nutrient, it can lock out several others..

This is a ph lock out graph.. Certain nutrients like a certain ph.. If the ph is out of range, the nutrients won't be available to the plant. The ph of your nutrients before you use them should be about 6.0 to get an acceptable range for most nutrients.

The ph of my solution is at 6.8-7
And I cant find my damn soil ph meter. It’s doing my head in, expensive Hannah one.
should I Lower my ph to 6.0 for my solution then?
I don’t know what to do about my soil without my pen?
on that graph it looks like all food can get taken up at 7 ph?

You can always do a runoff type test. It is not nearly as accurate but can go you an idea oh where you are
