Nitrogen toxicity?

Just noticed a bunch of my leaves are cupping and limp

Nitrogen toxicity?

For sure!

Could be ph, overfed, too damp, too much nitrogen etc, etc, etc.

Need information dude, lots of it. Put everything about this grow down.

Starting with -

Medium?

Ph of water, feed and medium.

Npk%?

Nutrient strength ppm / ec?

Watering frequency?

Feeding frequency?

Anything else you feel might help put it down, any information is useful information.

At a guess, looks like way too much nutrient, probably a low ph also, looks damp too. But who really knows without the info.

The two clones are a soil peat moss mix in plastic 7 gal pots

The zen hash plants from seed are in a coco, peat moss, perlite mix and 7 gal geo pots

Currently feeding PH of 6.0 to 6.5
Dont have a ppm meter yet

I feed/water every 2 days when the media goes dry

Using the Green planet nutrient kit



Relative humitdity 50 - 60%
Temps 18 to 24 c

I flushed the pots with some ph 6 water today and I'm hoping it was just the switch from week 1 flower nutrients to week 2 flower nutrients that got them

Any suggestions on things I can do to help them recover

Yeah, i think you're on the right track, it all looks more healthy today.

Might want to make it a very weak nutrient mix to rinse it out, instead of plain water.

All i can really suggest, i would have flushed it a little like you already have.

Good luck rest of the way.

Hey thanks

I splurged and purchased a blue lab combo hopefully I wont make any nutrient mistakes.

Went bad again?

There's nothing about your reservoir readings that implicate anything is wrong, so that's a good start.

Get a reading of your waste next feeding, so we can have an idea of what's going on inside the pot. Both ph and ec.

All looks good now that PH/ppm meter is great

Not really on topic, yet still relevant...
With having that meter(greatness), I highly recommend the Blulab Leap pH probe, as an extra... completely universal in liquid, and all media types.
Fantastically useful.

Peat has a PH usually between 3.5-4.0 if you don't rinse it.

Currently I'm watering with PH 6.0 nutrients and making sure there's a good amount of runoff to remove salts
