Hello there folks
my 30 day old autoflower NL, had a bit of yellowing at the bottom leaves, so I added Cal mag along with the feeding, two feedings later I did as usual, the next day the whole leave went yellow, how is this possible? could it be something else? like over watering, the 33 day old NL is doing fine.
I grow in light Peatmoss based soil with perlite
PH, Temp, Humidity are on point, i feed AN Sansi grow.


one other question are these Preflower? as it's too early and it's younger than the other one that didn't have this white hairs.

I am give me a bit literally just saw your thread this second. I will look now

So @koldvoid you use solely Advanced Nutrients sensi grow? You could be having a problem with salt buildup if you're putting it out of proportions with the niteogen, phosphorus and potassium.

Here's how a plant of mine that got a bit too cold then had too much nitrogen compared to its p and k.

See in the pic below how the top leaves are much lighter and have what I call "the death twirl", it's from too hot of soil either from early life or from some sort of nutrient balance issue

I think @Waira can give a bit better insight into what exactly is going on. Let's see of my summon will bring him over.

thank you so much for the reply, but the other NL didn't get effected this bad other then that first two tiny leaves which is normal, and another Cbd auto is a week n half younger n didn't get such effects, I think it's from having Lst and leaves being too close to the soil with hot nutritions, that would be just a random guess

Alright K, just my tuppence worth.
Either they (one of them) needs more food or light isn't getting to bottom of plant.

Either of these possible?

The calmag thing is potentially misleading and a consideration for making things worse.

If the dying yellowing leaves start at the bottom the plant and she alone is hungry (even if same strain - even if clones from same mother!) She will eat from those lower leaves first.

Additionally when the light source isn't powerful enough, again your girl will sacrifice lower leaves first...

Hope it helps.

Well its possibly that its genetics at play too. Are both NL from the same breeder? Whats the breeder? Whats the soil brand? What pot size?And do you have a side by side of both ? What kind of water are you using and what is the ph exactly you go for? And again, is it only bloom you are using? You look to have some imbalance. What's your light you are using? Led, hps, sunlight? What company is all your equipment from? Jace you cali rated your ph pen recently? Is it a cheap one from ebay/Amazon (usually yellow and has a black lid and top), did you cali rate it with the exact ml of water used? Do you have calibration fluid, so you keep your pen in calibration fluid? How is your p, not enough p and k are huge issues and it looks low. I'm sure I'll have more questions... just waking up so my apologies

Yes, same Breeder, Auto NL by Nirvana, I use tap water, which is left in a bucket through out the weeks, with AN PH perfect it brings out to 7.2 PH, so I add a PH down to bring it to 6.5
Viparspectra 900 for light, and German company peatmoss based soil, specially made for seedlings, so it's light, yes PH pen is calibrated n got two of them just in case.
like the above post, I think I misread N deffeciency and shouldn't have added Cal mag, the thing is that the rest v of the plant looks good heres done pictures

top two are NL, bottom Cbd crack by fastbuds, also as you can see one of the NL has pre flowers since a week, the one with the yellow leaves, should I switch to Bloom now or wait longer, also regarding LST should I keep her tied down?

certainly not the light, but I think it's the Cal-Mag, I'll go without Cal-Mag next feeding, it's flowering n I'm keeping giving her grow instead of bloom, hope it's not the cause, can't think of anything else really.

Alright K, just my tuppence worth.

a question regarding watering, every 3 days I water with 2 liters shared between the 3, they're in 3 gallon pots, so you think it's enough or too little seeing their size from the picture above? keeping in mind the yellowing I posted earlier was after last watering.
