so adjust it to 6 how can that be to low?


6.6-6.8pH soil - your soil is 5-8 times more acidic than it should be.

5.9pH is 10x more acidic that 6.9pH
4.9pH is 100x more acidic than 6.9pH
ect..

i recently switched over to growing large container trees in coco & have been seeing this problem. im currently treating it as a salt build up.. so a pH swing. everything is getting flushed out and receiving more plain pH'd water than normal throughout the flowering cycle. i've been using SeaGreen during final flush, but i've recently been advised to use it all the way thru, keeps the salts down.
 
Not the same plant, but same symptom. My hydrangeas exhibited same effect on their leaves after ph mismanagement. Hope this is the case for you since you've started treatment and plants improved.

stay away from 5.8 unless you are in water with bubbles. I`m not sure why you would think 5.8-6.2 is good for you. Prob some misinformation you read. Bring your coco to 6.5 or so. ;)

If you have 50% perlite and 50% coco, you could go down to 6.2pH. Coco does not flow as good as perlite and you will get a toxic ph spike from your nutes. Common problem for many people. I`ve been down that road many times, brother.


if you use soil and have a faucet pH of 8, add the nutes you would use and adjust your pH to 6.6. Trust me.. the 6.6 will drift upward since your tap water is high from calcium carbonate/chloride, it will stabilize and start the drift down.. You CAN give tap water about 12 hours of air bubbles after adding acid/pH down. This will create calcium nitrate/citrate/w/e instead of calcium carbonate (tap water additive), releasing carbon gas and probably some added chlorine.

I have 7.3 but I use 100% organic home-brewed teas, i adjust to 6.8 with 6.2 runoff.

as promised the pictures, a bit later as I said :)
the problem is still the same or maybe even worse though ...
these photos were taken after 10-14days growth.
I now put all my last hope on this easy ryder

It looks like a potassium or phosphorus deficiency, Magnesium tends to yellow between the veins. I am having a problem with that also that I cant figure out.

how many waterings do you do between feedings? and how long do you let the plants veg in the new soil before feeding the first time?

I normally grow in neutral soil but have now switched to BioBizz all mix, so normally I do not have to feed them the first 6 weeks..
if i use neutral soil i start to feed them after 2weeks (canna start) at low doses

pH still a little low and over watering. :) sorry man.. I hope I can help.

Look at the first picture, see how the bottom leaves are burning form the tips but the center is still good? Look also at the leaves above it with the tips curling. You are correct about the magnesium but more will not help much. You need to raise the pH.

The low pH is locking out the magnesium and this is causing the nitrogen to lock out.


sadly, look at the last pic.. the leaves bend down = over water..


my advice?

get some soil and PERLITE in a container without a plant in it, flush it out with pH 7 water until run off is almost clear. fertilize the soil with a 1/4 strength application of your all-purpose stuff @ pH 6.8 (make sure it`s 6.8), ONE DOSE ONLY!. If you can`'t make sure you are at 6.8 exactly, just use distilled water + fertilizer and no added pH down.
One Dose Only...

:rasta:

then replant your greenlings in the new soil. You could have a problem with the BioBizz running too hot.. especially if you are adding additional pH down or your equipment is not 100% accurate.

This will fix the over-watering and bad pH. The healthier plants will spring back to life in about a week. Old leaves will not repair but new growth should look a bright green color. It seems your pH got into the 5's and caused the mag lock-out.

thx for helping :)
but I now give 6.6 ph water, is stated on the packaging of the bag soil that has a pH of 6.6.
well where a used to grow before my ph whas Always around 7ph just tap water never had any problem,here tap water is 8.5-9ph
i also have a brita water filter if i filter my water here its 7 .. so maybe i better try just filterd water without ph down.
sry for my english hope you can understand it :)
