New to Coco, What's wrong with my girls?!

[Crunchnasty13]

Hi all,

Just started growing in pure Triple Washed Coco from House and Garden with mills nutrients, and adding supplemental Cal Mag recently. Here are some photos of the plants: Gorilla Glue 4

Looks like a deficiency, or nute burn? All leaves from middle to top are pale green to yellowing more with the new growth. some cupping in leaves as well. Also some plants growing shrubby, with way too tight of inter nodes, and weird leaves that are distorted or twisted.

I'm not sure what the heck is going on here. I've been watering with medium to low dose nutes every other day, water to waste by hand, as I've read that coco does not like plain watering, but more like hydro, a regular feeding with 10-20% runoff. Not really sure what I'm doing. These are all in veg in 2 gallon pots, 18/6, 55-60% humidity with temps around 72-76, 6.0 PH going in water, and runoff. PPM is 500 or so. Lights are approx 2-3 ft away from canopy, under 1000 watts. I recently rinsed the pots with 1/4 strength nutrients, in an attempt to 'unlock' any salts or nutes that may be bound up.

My instinct is telling me its a cal or mag thing? I used to grow in soil, and im not used to the soilless thing, but excited to learn. Thank you all for your help.

Regards,

Crunch

looks like pH lockout and that in turn is causing multiple defs... I would lower the pH to 5.6 and see how they respond..

Any chance you happen to know what EC 500 ppms is?

EDIT: ok so thats about 1.0 EC... I'd really like to see your plants as a whole as this is really a very light feed for coco, I only use EC1.0 on seedlings... by the looks of those fan leaves (size I mean) I would think you should be giving more like 1.5 (750 ppm)

PLEASE NOTE, PPM IS DIFFERENT FOR EVERY MANUFACTURER SO BE SURE TO APPLY THE CORRECT CONVERSION - this is why ppm sucks as a measurment and EC is always better - it's universal, there is only one EC... not one for Hanna, one for Blue, one for Eutech etc...

pH 5.8 for H&G, I experienced lockout at 6+ (unlike Canna)

Read the post, he's using Mills.

Mills has a fair amount of calcium and magnesium, why are you supplementing?

What is your tap water EC?

How much Ca/Mg are you adding?

How dry are the pots getting between feed?

Whole plant shots are helpful. I also agree with Jamie, you're probably underfeeding as a whole and potentially overfeeding Ca/Mg/N.

Hi guys,

Tap water ppm is approx 150-180, but I was told to filter it for running coco / mills - so everything has been fed with RO water. Also, someone I know who grows with Mills said that he adds cal mag in addition to Mills, because Coco sucks up the cal & mag hardcore. I started having issues with these plants, so I figured maybe it was cal mag, and started adding. I'm adding the low to medium dose of Cal Mag + of 1 tsp to 1.5 tsp per gallon.

Also, I should mention that I used cal mag because beforehand growth was not right, the plants seemed to green up for a day, and the next day I re-fed with the runoff water I fed them, and thats when the real problems started up. It sent the plants into crap mode, but everyone thinks its something different, so I'm super confused. Since then i've only made new water for feedings, and been tripping on a thousand possible answers.

Also, I have been letting the pots not get dry for the most part because I've been warned to not treat like soil. Which is why I've been watering every other day, maybe I'm not watering often enough? The coco stays moist.

Add more calmag.... if your usin ro it has to be added. Dont care what nutes your using its a must with every line ive ever used.
They also look hungry to me, hit em with 800ppm i bet they green right up for ya.

Try watering once a day around the same time, if the pots runoff right away thats too much, If plants droop then they arent ready for that. Moist but not wet and the pot is half as heavy and some runoff easy each time is where i like it.

ppm meters check EC and convert it to ppm, problem is makers of these pens use different conversion factor.
You would have a much easier life using EC values and finding your conversion rate.
At the point your at you want 1.2-1.4 mS EC.

It seems like you are underfeeding, there is a K deficiency and the pH also seems a bit off.

You want to water with nutrients EVERY day, and better yet - multiple times per day.
A drip irrigation system will make your life so much easier with coco.

did these ladies go from clones to straight 2gals under 1k ?


if so light stress.


i never ever ever go to a 1k on a fresh clone. under the t5 they go until roots get established. idc what anyone says even when started high up my girls dont like it. They go under a smaller wattage first and then they move under high wattage as they grow bigger
