Thanks for getting back to me again mate.
i made a tea last week with
200ml palm tree ash 0.1.30
200ml bat guano 1.10.1
200ml Bone meal 3.9.0
200ml Ecothrive 3.2.3
1/2 tbsp epsom salts
2 tbsp molasses
Ph 6.5 using lemon juice.
Aerated for 24hrs.

if anything, I thought i may have over done it with all that. i checked the light and it was 10inches above canopy so though maybe i bleached the leaves. My knowledge isnt great as this is only my second grow.

Maybe microbial life is your issue... If Endomycos and beneficial bacteria aren't there to break down your feed then it looks like a deficiency. Em-1, grokashi are great short term and jobes spikes are good long term since they break down slowly.

Overall total plant health looks good for week 4 flower. All new growth is healthy.

Hope more people have some opinions...

Hi guys,
Just wanted to share a few pics with you after the feeding last week. Do you think this is a nutrient overload and needing flushing or is it normal for leaves to yellow like this going into week 4 of flower
It looks hungry. They demand a lot of P and K at this stage.

this is where i noticed yellow leaves in middle of canopy on 2 plants. 1 of the blueberry and hifi 4g.
Do you think it could be from too many nutrients or not enough ?
Ive been trying to do some research and cant seem to get anywhere. I doubt its a nitrogen deficiency as the yellow leaves are in the middle / upper section, aswell as at the bottom.
Look up iron chlorosis, it's usually from too much phosphorus like the bone meal. https://cultivacegrowth.com/foliar-information/

Some nutrients are broken down faster than others. As an example guano is a prettty hot amendment which will break down faster than something like oyster shell flour or fish bone meal.

Like Poly said, runoff isn't a great way to check the soil pH. It can give you an idea, but it can also be misleading. If you wanna know the true soil pH, a reliable pen works well. You can do a slurry test too, but it probably won't be as reliable.

Hey, this is cool! I have an old analog Kelway Ph meter that I have been using. I didn't see any digital soil Ph pens when I was looking, I must be getting old...

Thanks for getting back to me
im not sure whether to give it a flush or give it a few days to see if the yellowing progresses the same way as described with iron deficiency

I wouldn’t flush. That usually makes things worse in an organic grow.
thanks for the tips mate i wont flush
ive tried doing some research and it could potentially be caused by rising ph from the palm tree ash. Its suggesting i should ph the water to about 5.5 to bring it back down in the 6 range.
not sure but im over thinking about what i can do because the yellowing is spreading to the sugar leaves further up the plant to the buds now.
The strange thing about it though is that the other 3 plants are perfectly fine including the other blueberry.

Ive taken a few pics under the leds but altered the camera settings on my phone so the affected areas stand out. The illuminated lighter pink colours are the affected leaves. Under natural light they appear very pale green, losing all vigour and life.
I did read a post from a guy a few comments back and i think he mentioned about iron def which would make perfect sense if the ph has risen into the alkaline sector.
im not sure i can save it now as there’re only 3.5 weeks left.

It’s going to be to late to make any noticeable changes in this grow. Organic nutes take a few weeks to take effect and by then you’ll be about ready to chop. Just try and keep her as happy as possible these last few weeks and you’ll be fine.

plant doesn’t look to to bad in my opinion for being 7 weeks into flower.

Thanks for replying mate.
Im not sure whether to feed them now as the tips are slightly burnt on the plants so they’re already charged up. Ive just gone into 4th week of flower on saturday by the way. They’re 8 week strains. Ive got 4 more weeks so hope they dont phase out now.
do you think watering with worm castings tea with epsom salts and molasses will see them through the next 4 weeks or would you give a light feed sprinkle of say 50ml bat guano 1.10.1 and 25ml palmtree ash 0.1.30 ?

To me the plants look hungry. Looks like a big plant for the size pot you have them in. Next time I wouldn’t veg as long or plant in bigger pots.

A tea is never a bad idea. I can’t recommend that palm tree ash because I’ve never used it. I don’t like putting things in my soil that have such large numbers in the npk area. That 30 of potassium might be putting things out of balance. Do you have any all purpose dry amendments you could use?

Theres one ive got called ecothrive charge npk 3.2.3. Thats the only thing ive got thats quite balanced and not too hot.
The bat guano is 1.10.1 so thats pretty hot to i suppose.
I agree with you in the sense that they do look hungry and the last time i fed them was about a week or so ago. But i gave them a tea of 200ml each ! So if anything ive probably over done it. Ive just been watering with plain ph water as ive topped dressed twice in the last month so id imagine that would take the plant to harvest and is it true just by watering the soil it will activate whats already in the soil.
Maybe a light top dress of 50ml of bat guano and 25ml of palm tree ash might do the job but then again less is more as they say so dont want to overdo it either. Its mind boggling lol
Just to let you know they’re all in 7 gallon pots which is 30litres so id have thought there’d be plenty of room in them. I veg’d for 6 weeks from seed and im 4 weeks into flower, 4 more left. I tried raising the lights up a few inches just to see if it can help as too low light will stress the plants and cause them to feed more than they can handle so just moved them to about 15 inches above tops now.

Microbes in your soil is what will break down the organic matter into food for your plant. A tea or a top dress of earth worm casting is perfect for that.

You are a little late in the grow to see any drastic improvement using Organics.

A top dress of some of that all purpose and a little guano followed by a tea is a good idea

do you think i could mix the guano in the tea instead of top dress so it hits the roots quicker ?
Also are worm casting teas good for correcting ph ?

Hi guys,
Just a quick update. Im in week 6 flower now and extreme yellowing.
I believe it was the palm tree ash that raised the ph of the soil from 6.2 into the 7’s, hence the extreme yellowing. I know its normal for leaves to fall off and yellowing to occur but this is extreme.
Ah well i think ive learnt for my next grow now.
i dont think i will use palm tree ash next time around as im convinced thats what done it. It was fine before that. Maybe use kelp meal instead next time.
I did some research and it seems that iron is locked out when the ph goes into alkaline and thats what my symptoms appear to be.
ive still got 2 weeks and hope they’ll be ok.
i did water with a ph of 5 / 5.5 just to see if that will help bring soil ph down or whether im better off just sticking with watering at 6.3.
i wont be giving any more dry amendements or molasses and epsom salts, just pure water for last 2 weeks as the soil should have more than enough in it. If anyone else has input or different view, any feedback would be much appreciated

Have you looked into mixing your own soil up for your next run? I think it would give you a little more control of what you have to start with and allow for a more basic approach of things after the soil is all mixed up knowing you have your basic needs covered from a proven recipe (something along the lines of coots mix is what I use). From there, you can experiment and try different things out. That's the route I took and am still trying to put it all together, but things tend to go more smoothly for me the less I try to force things onto the plant/soil.

As for ph in the soil, I think a basic ewc/molasses tea would help regulate it back to a more so stabilized environment if you run into this issue down the road on your next grow. The microbes should balance things out a bit as they get settled in and start to work through the organic material in the soil, don't quote me on this, but I think I remember reading something along these lines. PH seems to be a tricky thing and everyone seems to have their opinions on how to approach it from my readings. I subscribe to the not ph'ing anything and hope my microbes keep everything in check as long as I don't overdue anything one way or the other. Other members on here who I think know their stuff pretty well seem to be on the other side of the fence, so to each their own as long as it's working for you.
