Really dumb question.

[diskokobaja]

I didn't find this anywhere so I got to ask here.. How long does it take for plant weed to being up taking of ferts after feeding, and if I miss pH would the problems will appear immediately or they will build up.. I'm asking coz I'm using pH perfect AN. and I got pH lock, I fed my plant 4 times till now and only last time I've checked pH after add in AN ferts and it was 7.6 so I lowered it with pH down.. after that yelloving from fan leafs has infected upper leafs.. So did my last feeding fcked up pH or it was slowely building from first feeding??

What did you use to check your PH? Unless you're water is very very unstable AN will put it in range and you should never have to PH the feed though. It buffers very well. Are your nutrients OK? Not old or over concentrated? Shake them week each use until little foam head is created on top? Using the PH down may have destroyed the buffet created by the nutrients and threw you into lockout. I've been using AN for about a year and I've used both tap and RO+Cali magic and it's always been mix and go....I would say adding the PH down was no good, always check bottles too....

If using a PH meter make sure it's calibrated and cleaned. I ruined a couple girls with my cheap meter and not taking proper care of it, I run nectar for the gods as well as AN so I have to PH that, now that I got a good meter and take care of it I don't seem to have the issues I did before

What soil are you using? Coco isn't soil either, it's a soil-less medium.

I have e bay cheap chinese ph pen..two of them..When i was 3rd time feeding them i checked pm 7.5 (my tap water should be around 8.6)after adding AN, but didnt touch anything, im using bloom A/B from AN big bud, voddo juice, b52, the plants looked ok but my fan lefs were yellowing , but I know that bloom ferts dont have much N so i didnt worried, when i last time feed them (i feed them every watering coz they are in 18l pots and i water them every 7 days) it showed again 7.5ph after adding AN , so i decide to lower ph with ph down.. 33h later upper leafs started to yellow.. I must add that my girls are around 55 day, i never added calmag ,because they didnt show any def, and my tap water is hard as d*ck on viagra..

What should i do know?? flush? fed them regulary without fckn with ph down, something else??
They are in soil with 20-30/ perlite.. Soil isnt a problem.. If it is the problems would shown earlier..

Led.. Photon 6.,

Not that I am very experienced, and there are a lot more knowledgable here to advise you....

But, I have found that plants under LED's often require more Magnesium (Only Magnesium, don't use Cal/Mag if your water is already hard).

As I said.... I am a mere novice, but that's something I would seriously consider.

But would not it shown much sooner? They are in 50 day of life..

Ph can go haywire at any tome of the plants life.. I strongly advise getting a ph-Wizard
