weak strain or what?

[Kaellan420swe]

4 difrent strains only one looks fuckd up.
to mush neut N ?
6.0-6.4 ph
Around 3000-3500 ppm (use bloom boost as ph downer).
Cooco airpots.
I have had gnats befor buth i killed em all, maybe dmg from that?

Not sure what happened but let it finish. it will do ok just not as pretty as the rest but dont pull pull it.. unless you see rot..

Maybe back off on nutes with that one plant.

3000 PPM?!

Good lord that's an extremely high PPM

3000 PPM = 6.0 EC right?

I generally would give them 1/3rd the strength you're giving them during the 4th - 5th weak of flower when they need the food the most.

The rest of the time I'd be giving them even less than that.

I had around 3000-3500 ppm whole grow tbh xD
Maybe thats why i always run out of neuts so fast

Should i use lemon juice instead of bloom booster to lover ph?
Or what ells to use?
Got no ph down first time in cooco.
Will go soild next time i grow i think, mush easyer to automate.

Its only 1 that dosnt like it

Bloom Booster generally can be strong stuff and is easy to overdose with.

I would do a grow and start at 1.0 EC and work your way up to 2.0 EC into flower.

pH should be 5.8 - 6.2 in Coco

pH Down I use Phosphoric Acid (buy it from a proper hydro shop).

Your EC (PPMs) is way too high and your pH is a little bit too high.

Your pH is too high, and you're over feeding. None of your plants looks completely healthy, so I'd definitely rethink the feeding schedule. You might have salts in the coco also, because you're feeding through the bottom instead of pouring water through the top which would then flush the excess nutrients out. But yeah, not a weak strain.

[edit] Coco is a hydro grow medium, you need to treat it like one. pH Down is essential when growing in hydro, but coco is still the easiest grow medium I've tried, even easier than soil.

Im using tropfer drippers so auto drip so its aleays mois.
Ph from runofs are 6.4 and 1400 ppm.

3000 PPM or about 6.0 EC is way way way way waaay too high

That is all

What else do you want me to say?
