I'm gonna take a closer look at what nutrients you are using, so my answer can be a little better. I'll get back to you later on that one.
I flush using PH'ed water.
oh and i havent been using the aminoextreme/bloom yet

I have a 50l bucket i use and halve the nutes reccomended
ok, are you using the water all at once or just letting it sit and use it for a week? If you are letting it sit, I would recommend getting an air stone. I also noticed when I looked back at the pics there wasn't much perlite on your top soil. How much perlite did you use, if any?

OK my bad i left that info out , the only perlite thats in there is the stuff that was in soil , yes i started with sooil and went to coco, was afraid to wash the roots , they have bout a litre of soil in the 18l pots. I always use a fresh mix, I could fully automate my system for like 30 euros and have been thinking of doing this to eliminate human error, Ofc theres learning to manage the res but i think it would be worth it. Was thinking a dtw, anyways prolly next grow just so i dont copmplicate this one further :D

The perlite that is in the soil might be ok for some growers. I still add some more perlite to soil grows. In coco you need about a 70/30 or a 80/20 coco/perlite ratio. Perlite helps with drainage. I can tell from the pics that you need more perlite. The fact that you used soil and coco could be an issue too. You're not only growing in coco, so using a ph of 5.8 would throw the soil off. I would have been ph'ing to 6.5 - 7.0. Automation always sounds like it's making life easier, but in reality it will make your life harder until you fully understand everything going on and have it dialed in.

The soil makes up 1/18th of the coco , would it not make sense to adjust ph to cocos needs seen as thou thats my main media?

Possibly, yes, but I wouldn't look at it like it's your main media. Coco is basically sterile without amendments and soil comes with some goodies in it. Even if it's a small amount of soil it could damage your shit because remember soil and coco have different ph's. Even if it's an 1/18th of soil, there is still soil in your coco. A little Ph problem can cause a larger problem in your garden. I don't think we would be able to definitively narrow down one thing which is the cause of your problems, but next grow either use coco or soil, not both. If you do use both use more of the soil and treat it as a soil grow. If you go with coco, go with 80/20 or 70/30 coco to perlite and you will be set there. Start with 1/4 strength of the recommended nutrients and work up as needed.

so what do u soggest my next step should be?

the reason your getting MG def is your PH is too low for proper uptake of cal/mag,let it drift up to 6.5 a couple of times a week, also dont let your coco dry out completely

i thought ur mnent to 5.8 ph it , guess not all is true on the internet

if you look at the chart PH ing at 5.8 constantly will lock out calcium and MG altogether, you need to vary the ph over a week to catch all of the elements that the plant needs
you say 1/18th of your media is soil which works out about 5%, that will not make any difference to the ph treat it like coco ph between 5.8- 6.5,

I don't agree that the soil couldn't hurt. Soil has amendments that are released, regardless of how much soil is in the pot. If the ph is 5.8, those nutrients from the soil are still going to be used, but improperly. Your plant could be confused. It's not like growing soil and adding coco into soil where you added no amended value. I agree that you should swing your ph from 5.8- 6.3, personally I don't go to 6.5.

theres not going to be any nutes left in that compost that haven't been used or flushed out by now, just buffers left, imho
so your saying ph between 6.5- 7.0 in a 95% coco media, wheres @coreywebster when you need him

You need a friend to step in to help you? It looks like he barely has any perlite in his pots, so there could be shitty drainage going on causing root rot. I'm not saying you do 6.5-7.0 in 95% coco media. I'm saying that there are issues with having soil in coco and ph'ing to 5.8. The soil could cause damage, so could proper drainage, so could overfeeding, so could only having your ph @ 5.8 the entire time in coco. Yes, the soils amendments could be gone NOW, but maybe not when the problems started.

I might be a few days late an a dollar short but even with the quality of the photos, you have powdery mildew and those caterpillars that aren't so bad have actually ate holes in the leaves. Spider mites are bad but never seen damage like that from a spider mite. Chances are you may be controlling the mites but they are still there, the caterpillars are feasting and the powdery mildew is gonna choke the entire ecosystem you have going there causing death to all participants in the game including the host.

nah, quite confident what i have said is reasonable advice just lookin for the opinion of a more experienced coco grower thats all, no need to be shitty, we are british after all
