What kind of deficiency is this?

[Stevo0121]

I’m using 4x650r by HLG in a 2Mx2Mx2M tent. My first time using leds, but the bigger plants have started to yellow etc ive given them extra cal mag, and feed them flora 3 part series. Do you need to feed more often when using leds? I just can’t seem to get them greener at all

 

[Stevo0121]

It’s the 3 big ones mainly..

How much are you feeding?

Why is your coco only wet around the base stem and not the whole thing?

I’ve upped the feed to 5 litres every 2 days for each pot, and the e.c is at 1.4.16 as they need extra cal-mag I’m guessing.

I know I’ve just started to feed way more often as the intensity of light is strong so there using way more energy than i thought.

How much cal mag are u giving? Also the watering needs to be everyday, probably the most important . Have you checked the runoff EC ? You might have a salt build up

How can you test the run off if there isn’t enough to test ? There only in 5 gal pots and a saucer underneath? And I’m using about normal strength and a quarter, and ok I’ll feed them everyday that’s not a issue just treated them like soil under hps lights , completely different.

Shoot your plants actually look happy taking a second look. Might not need to water everyday . Biggest thing for coco is runoff though, if you don’t get enough your salt will buildup and the plant will suffer..And how much cal mag is normal strength to you, how much per gallon of calmag. I actually had to flush my coco plants last night I use lil dish racks plop the plant on it and flush through to the saucer.. or you can take it in the tub… when you flush, flush with 1/4 dose nutes 2gallons of water per gallon of pot size. Flush until your runoff is the same as what you’re putting in

Yeah I think it’s a salt build up I flushed them and now they’ve gone yellow a bit but the big ones have gone green, now the little ones have a deficiency, it’s got purpling on the leaves and I give 1-2 ml cal mag per litre as it says on the bottle so I add say 100 ml to 80 litre reservoir.

 

[Stevo0121]

What’s the purpling? They are all still growing good it’s just they could be better one I solve this deficiency

And I haven’t used that superthrive btw it a empty bottle I used..

Anyone??

Hi
Looking at the video, I noticed some burt tips, which indicates nutrient burn, try cutting back.
Also, the browning of the leaf edges along the sirated edge indicates too much water.
Try not to water too much. As you have changed lights to LED. They produce a lot less heat.

You said Anyone?

Ignore the purpling. It's genetic. Usually triggered by temps.

There looking a lot better, a bit of calcium deficiency, but that’s getting corrected
