I root cuttings in plain water since I had lousy strike rate
with rooting in coco.

Transplant to coco mix in 16oz cups, micro style.

165W PL-L in flower, 72W PL-L in veg.

I'm no pro, but I have better all around growth using 1:4
old to new.

I boil my coco between use too, much to learn. I'm thinking of
going new 100% all the time, but I'll need to be
convinced to ditch re use all together.

Good thread.

Haven't used H&G in a few years but got a lot more purple leaf stems when I did.

Are you always using recycled coco for the final transplant? What I am getting at is some people have issue with over recycling. They tend to graduate to mixing in new coir around 70/30 old/new. Never tried it myself for very long.

Why you advice me to drop epsom? Do you think I have enough magnesium? To me plants looks like lack magnesium but i can't noticed improving from upped epsom.

Ok this is what I do. I transplant in to 1 gallon fresh coco not reused. Let them dry and feed with 1.6 e.c. Canna coco a&b at 3ml/per litter (12 ml/per gallon) once. Next feed I goes back to 1.4 ec and switch back to h&g base. They look greener and perk will see what happening.

Currently feeding seeds with 1.3 ec including 0.2 ec epsom. They also looks like lack something or may I over thinking.

New growth can look pale, especially at lights on.

I suggested removing the epsom to increase the amount of base nutrient.

For seedlings or just in general.

I'm gonna say it again - Stop letting your plants dry out and your problems will go away. Coco should -always always always- be wet, if you see dry coco (even on the surface) you aren't watering nearly frequently enough.

Work with clones primarily. I've only noticed it twice in the past few monthes on the healthier plants after someone raised the point. Pretty rare I am around at flips or that think to look for subtle changes, being a hamfisted meathead.

I get lockout when i transplant into coco.. especially if i make a big jump i.e. solo to final containers.
Coco should be moist at all times, and can't be overwatered - WHEN ESTABLISHED.

It's a whole different story in the beginning. Overwatering is easy in unestablished coco pots, and will cause lockout.. It will look like Mg and/or K def. sometimes Ca, sometimes N.

Honestly your pics look basically fine to me, so i can't say for sure. But i will tell you it happens to me every time.

It's a matter of dialing in the right level of moisture at transplant.

Once your plants are established, never let it dry out (as beta said) to avoid salt crystallization and build up. The nice thing about coco tho, is that if you do build up and lockout, it's pretty easy to flush and reset.

I couldn't disagree more. In fact, I'd wager a bet that the reason you see 'lockout' when you transplant from small to big containers is because you aren't watering for a long time after the initial transplant.

Coco naturally holds the proper air to water ratio. Just like pure hydro roots can be submerged in pure nutrient solution 100% of the time, you could leave your irrigation system on a freshly transplanted clone 100% of the time and it'd be just fine.

A weak argument can be made that roots grow a little bit slower if they're constantly kept wet (the 'lazy root' theory) but in my experience if it's true the effect is subtle and almost always WAY overstated.

The bare minimum I ever water any plant is twice per day - Even fresh transplants going from a small to a large pot. If you're not watering coco at *least* twice per day you aren't doing it right, at least imo. Whenever I stop watering at least twice per day, I start seeing problems.
