That's not contradicting...

Hi Guys,

First grow in coco and I've got (I think) a calcium deficiency on a couple of my plants. When reading on the good old deficiency I became a little confused.

I've always been taught, well I read:

Water once a day, if you can twice a day
Never let the coco dry out and always keep it wet
Water with Nutes to run off of around 10-25%
Water the plants at a PH range of 5.8
to ignore Run off Ph readings. It can vary from 6.3 to 6.45 dependant on plant, and it doesn't seem to come down when If I watered at 5.5

When researching Calcium, I'm reading that its best taken up at PH 6.2/6.3.

So its really confused me

Do you have a set PH you water at, or does is a multi factor dependant?

Change your PH range around within 5.8 and 6.3

ph for coco i alway run from start to finish 5.8 to 6.3 max but i set at 5.8 and let it drift up

what are u feeding ?

also how hot is the area ?

What do you recommend? I water my plants at 5.8. If I water them at 5.5 it still doesn't really bring my run off down

Its around 19c-23c

Water with solution phd to between 5.8 and 6.3. continue ignoring runoff.

do look at your run off its a waste of time. are u letting the pot dry out at all ?

No I don't let the pot dry out. I water once a day at the moment (Their 3 weeks old on sunday). I always have run off of around 20-40%. My watering EC at the moment is 0.8 with Canna A and B, I've increased it to 0.9 and will slowly increase over the next couple of weeks. Run off can vary from 0.4ec-0.7 EC

Just coco mate, canna Professional + i Think its called

What's your light height? And what's the light? That might also cause some burning like that

Do you think its burning and not deficiency? Lights about 16 inches away, 600w HPS through a digital ballast

Raise your light about 8-inches. That's too close for those small plants. Also, are those clay pots? If so, I'd avoid those.

Yeah, agree with PJ

Listen to PJ. Those plants are way too small for a 600 watt hps to be that close. You are essentially forcing them to try to transpire and grow at a rate that the root system and amount of foliage present are not ready to deal with.

If I knew how to like comments, Id of liked them all

Much love, Thank you

Good luck, reply on here in a few weeks, let us see em prettied up!
