HELP!! plants are suffering

Hi all,

So these plants are under CLW SS550s on a 24 hour lights on cycle.

There were 2 nights in a row were the power cut and the lights were off for the the better part of 12 hours. Once I had corrected this I noticed they had started to flower so I changed from 18/6 to 24 to try and reverse them back to veg.

Then all of a sudden I began to have issues with my heating I left them unattended for 3 nights and the temps dropped to 13° celcuis for what I'm guessing to be 3 days straight.

So now I'm at 24hours lights on, temps sitting at around 23°celcuis and following a feeding schedule as provided by CX nuitrients but the plants are looking sickly.

Ive just transplanted into 10 gal pots and the root balls looked really solid.

Need abit of knowledge in how to bring them back to healthy again. They look to be suffering from a deficiency but I'm not sure what exactly.

Tap water comes out at 0.1EC and I PH to 6.5.

Any thoughts please let me know.

Cheers
Holy light bleaching Batman! That's severe light bleaching. Start with the LED panels at the highest final height and let the plants grow in to it. Don't do 24h hours light shedule and read up on DLI(daily light integral).

You need to dim the light asap to let them recover.

Correct Robyn lmao, I seen the light bleaching also and dimmed the lights straight away. I had just turned the second light on still figuring out the solar system 550s.

I had a quick look and it isn't obvious how strong the soil is, along with how much of the nutrients you have used within the soil. It's a massive complication, imo it is better to go all organic /// or all synthetic in coco, unless you are very experienced in mixing the 2.

The CX nutes you mention have both coco and hydro variants, I could not find an organic version, and the fact you are talking in ec makes me assume it is the hydro version?.

None the less, from the EC values they give you should be feeding closer to 1mpl of both A+B, giving an EC of 0.6 on your total base. That is accounting for the fact you are using soil. The ratios of npk are something around a 1.5-2-3.

The growth enhancer is just N. I do not know what kind of N, hopefully with calcium. However given the base EC and ratio above, along with using soil, It seems like you can use that at 0.5 mil per L, or 0.75 max.

The bio balancer reminds me of the enzyme products, although it may be something else given the microbe statement. It has ammo N in it and that can create problems in coco, although some is needed in soil if I recall. I do not know enough about all that other than to say you have a very complicated nutrient mix.

I got to be honest the other two products are just following suite. If you really want to use them I would recommend dropping all those additives to half recommended.

I would have advised you to just use the A+B@ 1mpl each, and the growth enhancer at 0.5mpl, and that's it. However I do not know what is in those, and if your calcium and magnesium is covered. Along with the complication of not knowing how strong your soil is. But that's my best guess, up to you.

What I can say for almost certain is that shooting for 1.6 EC while feeding wet/dry cycles in soil is not going to end well. If any microbes are present, they will be killed off by the draughts/salts or discouraged by the higher synthetic values. Anything above 60ppm P begins to turn associated microbes away, the roots don't need them. The other elements will likely work on a similar concept with the relationship between roots, instant synthetics uptake, and need (or lack of) to call on microbes for help. That is where the real complications come into play.


Try watering with the recommendation of keeping the synthetic feed under 0.8 ec. Water to a little run off every time, you have to in this setting. Wait a few days and then repeat (always with feed in the water). If you do not do this then the organics in your system have 0 chance of working and are complete waste of money, along with altering your PH to a range that is not good for synthetics, so then you get both worlds of deficiencies, lock outs and salt burn. The problem you have is that you need to catch the plants just before the begin wilting, in order to limit salt damage in the soil, however if you water too much you will end up with wet feet and over watering. You've kind of forced yourself into that position, and it won't be an easy one to navigate.

For the future, use coco and get a simple nutrient line. Cana A+B isn't bad, and use the calcium additive if needed. In that setting you can start pushing 1.4-1.6 ec. The other additives you are currently using (apart from the N boost) appear to be marketing hype, just like canna terra, AN and all those other snake lines.

Thank you so much for your advice, Canna A&B was my first choice and abit of rhizo but the day I walked in to purchase it all they were out of stock. So unfortunately I went with the CX line.

I'm using the coco A&B and not the hydro as directed by the staff member at my local grow shop, who also sold me the rest of the product line bio, regen a root etc‍♂.

I'll definitely apply your methods moving forward.

Cheers Flowki
