I just ordered the micronutrients so hopefully that will fix things. And your plants look so nice, I wish I had the luxury of getting the good premade formulas but they dont sell them here.
Help, leaves are so yellow.

That's not a problem but in the meantime I'd suggest you move to a soil rescue now. When your plants get larger cut clones (so you aren't losing genetics) and start running tests of your own mixed nutrients on the clones. There's no pain associated with killing a clone, as long as you have more of them.

Sadly they are autoflower.

Nope try again...perhaps 1.4 (note the decimal point). That would be around 700 ppm
JD
edit...so I realized from your posts that you don't understand that EC and PPM are different measurements. Yes they both measure nute strengths...but to us literal minded sorts 1400 ec is nonsense.
Ouch, I'd do the soil rescue and buy some photoperiod seeds for the next time, sorry.

The tds meter I use shows the EC as 0000 so when I measure it comes up to around 1400 which I assume means 1.4. In any case I will try everything you suggested.

It's okay I'm still learning and I appreciate the time you spent to give me suggestions and motivation.

Doing some research I think it is nutrient lockout due to high sodium in my unrinsed coco coir that I bought from a local market in Bangkok. I'll be the first one to call myself stupid.

Mario...I've been growing in coco for over a decade...and saw lots of problems from sodium. Not sure the plant would have survived that long...if your coco was that bad. But it may be a lockout from too much food.

I'm going to start a flush today, from your personal experience do you think they will survive? I'll document it if you are interested.

Mario,
Be sure you have something in the flush water...1/4 nutes will do...or calmag. Flush with at 3 times pot volume. Then reduce nutes...never give straight water. Don't let them dry completely...water at least every other day. Yes I think they will do OK if you do that.
What I meant was with excess salt in coco...they usually die in seedling stage.

Man you are really helpful. Thanks a million my friend.

Sure thing...and yes, keep us posted. It's good to know if advice given actually works. We like feedback.
JD
I too would have expected the Na to have taken them out far earlier. I hope he lets us know if flushing solves it.
