You will get salt build up. Period. You have to have good run off in soil.

Goes back to the dry spot thing. Peat gets hydrophobic. Its why I said to water it several times.
If you have to set them in a tote or.something and let.them sit.in water until they soak it up.

Got a pic yet in normal light. It will help a lot.

What light, did he even talk about the light lol.

White is right lol. Water in stages and water till runoff, maybe I wouldn't go 30% but I'm cheap lol. that's why you have drain holes in plastic pots lol. If you don't water in stages you'll possibly miss most of the root system. As for what's going on, yup better pics without the purple haze going on

I'm still like "wtf" over the 1300 ppm feeding on q small plant. That would fry the poor thing.

U can see all three plants have the exact small yellowing leaves, even on the same side while the other side stays ok. And it happens to the non trained plant too so its so its not stree from lst, i tried to water with ur method with ro phed 6.5 water yesterday and lets see how the girls reqct in a few days

What strain? That dark so.91st black color in the new growth makes me wonder. Its either genetic, temps or N tox.
What strain? What are lights on and off temps and are you grow in a basement or are those pots sitting on a cold basement or tile floor?

Hey its caramel mandarin from sweet seeds, i ve grown many of there colored genetic and in fact this is the first green clour auto i m growing, but it has lavender cream in its genetics which would carry some purple trait. I ve read some threads people say 20% of the get purple phyno so i guess its not really huge issue and u can see the green phyno one has no purping whatso ever so its not from environmental stress...
I m growing in a studio room with hard wooden floor and i guess its the house centrol control tempurature system

Sorry and lights on right at too canopy 26-28, at night prob 22-25, dont flactuate since its centre controlled

Hmmm.
Then its the watering problem. Possible dry spots. Salt build up locking out N.
It could use some P and K.

Yea i just flushed with RO phed water this time, and it def need bloom feed rn, but yellowing did sollow down! I ll keep u updated man! Thx

Also before i was realizing my local water is hard af ph at 7.8 tab water... could that contrite built to salted built up? I used it 2 times but both time used phed down to lower ph to 6.5 but still water is very very hard...

Hey Has anyone considered the possibility its N tox, leaves that are not yellowed look that flat matt dark green colour, slight clawing on the tips. That would add up considering the ppm of the feed. The progression of N tox leads to the leaves yellowing in that mottled pattern and dying off. Plus you often don't see burned tips with N tox like you would with general nutrient burn. Could be caused from underwatering with high PPM feed
Anyhow, just something to consider, be interested to hear others opinions on that theory.
East side grower Yeah with hard water you need to use a light feeding, the harder the water the less feed. Depends whats in your water, you can google your water supplier to find out exactly what's in it. I have hard water and most strains like a light feeding apart from the OG which takes as much as I can throw at it.
Take what I say with a pinch of salt, I'm no expert but its worth considering the possibility before treating N deficiency.

man u sound 100% been using hard water for a while (real hard) and just feed on that without run off, i dont have a ppm but i thinn its like twice the normal city ppm would be. We have bad ground water here...

They are at 5-6 there is no vertical streach so far but but should i keep feeding n on top of p k?

I mean 5-6 weeks from germination

Sounds like a very bad combo. I imagine a good flush with PHd water would do them good, get rid of that salt build up, then resume with a light feed. It may well be worth using a wetting agent too to combat any hydrophobic areas in the medium.
I believe a tiny amount of dish soap can be used as wetting agent but would prefer a second opinion from @whitebb2727 on that since its not something I have ever had to contend with. Would rather be wrong and told so than assume I'm right and pass on bad advice.
