Help! Yellowing spreading laterally. Week 7. Indoor soil

[Inf3cted]

In about a week the yellow has spread from the lower fan leaves up lateral branch and is creeping to the top! Is this just her getting ready to harvest? I don't think so!!!!

Below is my AmnesiaXXL #1 the healthier and stronger of the two (up until last week).


Im on day 52 of an AmnesiaXXL grow (check signature for journal). I have 2 of them and about 18 days ago Amnesia #2 showed definite signs of cal/mag def which I though was light burn. Soil probe showed the soil pH at 8.. Anyway since then a series of diagnosis and seems like i had lockout and defieciences due to that and I tried running pH water to lower pH using a vinegar aNd lemon Etx. Meanwhile Amnesia #1 pictured above also displayed some calmag signs and since 10 days has progressively been eating herself up.

I've been through all the diagoneses the only thing remaining is to test run off. I now suspect the soil probe is useless and that I have very low pH and not high pH. I will test runoff tonight aNd of there's a drop Is will know it's too acidic!! I've got liquid dolomite on hand if that's the case.

The buds have been resining up but not really swelling up.. See below

A nice tight closeup of the leaf would help as it appears to be either a nitrogen or sulfur deficiency but you need to get a more experienced grower than me to have a look .

Sorry im just at work poking around and didnt read far back have you flushed this plant with straight water yet?

The creeping upwards of the yellowing is classic Nitrogen def. I don't know about indoor feeding but even though the main thing needed for flowering is Potassium, they still require some Nitrogen, one of the experts will be able to help you. good luck man

If feeding the plant and still getting the yellowing and the def is spreading and you havnt done a good flush you need to in my opinion..... clean out the soil and wash those roots off and start from scratch then you know theres no build up and exactly what they are getting and how much..... if your not feeding living organic soil you should be good to flush with tap water I use 3 times pot size I use 5 gallon planters so I flush with 15 gal each when needed if your using a living soil ro water or bubbled tap would work but I would stay away from tap if your city uses chloramine I hear it doesnt evap out

Hungry IMHO, I would also say have you flushed and/or been getting good run off, stale water and salt build up can look like that.

Lol theres your organic man now..... dazed has spoken lol

Thanks to all the quick responses - appreciate it!

Please elaborate on what you mean by living soil ? Do you mean with earthworms and stuff the tap water here is very high pH and I reckon lots of salts.

i don't think its under feeding. It's good soil and had some slow release ferts in there as well as regular feeding of kelp and pro biotic soil conditioner.

I desperately need to flush and if RO water im gonna have to make 3 trips to the store on foot and buy as much as I can because I don't have a car and it's too short to take a cab. They are 12 litre pots so 36 litres ao I need about 18 bottles ️haha

All this while suspecting pH was high I think it's actually too low

will post feedback

Thats allot of trips and im not an organic guy but im headed that way but if you were feeding a living soil you would def know what I was referring to so we can just skip that for now but yeah if your city water is shitty I would get the ro and flush with it and evaluate from there it doesnt have to be 3 times the pot size its just a general thing I use but I have unlimited ro access and good city water good luck man ..... but I think you will see an improvement especially with the time release stuff in there... I have a white widow that git burnt up and looked like shit with time release ferts but after I began to flush she perked right back up with fresh green growth and began budding much better

+1 from me for a Flush (to get rid of salt buildup and correct PH) and Feed (those leaves look pale)!

I don't envy your trips to the store though!

I'm with Atrain too ... slow release ferts can be a pain in the arse for growing autos. I don't think i've ever flushed 3 times the size of the pot. I just never have 6 5litre bottles of water hanging around. >.<
