nutrient deficiency or lovk out

[thehulk]

Hi all ...
I'm a little lost over this one ... I'm nit new to this but I seem to have 3 plants I just can't feed enough nutes to ...
The leaves are pale the stems are red ... 2 of them I let veg for 5 odd months and the other u i revegged from my last grow ...
Everything else is healthy ... I used a organic nute this time not terra veg ...
Iv tried flushing them through and adding more notes at the normal feeding range suggested asmy last hope ...
Waiting on ph paper. ..

Very little information to go by, but two plants look very nitrogen rich, one plant looks like its hasn't seen any nitrogen in a while.

I would feed the 2 dark green ones less, and the light green one more, but that is going by the very limited amount of information provided.

Looks like lockout or underfeeding to me if its underfeeding then its a simple fix of just upping ferts but it depends what your feeding and how much.

If its lockout caused by soggy rootage and not ph related lockout you've gotta let pots really dry back before next feeds to fire the roots back to life which may take 4 to 5 days or more, popping pots on a heated root mat will help dry them back a bit quicker, just make sure pots are really light as feathers before next feeds if its this compared to current weight.

In meantime to keep plants ticking over maybe make a high dose mix up of your base feeds into a foliar spray and foliar feed just before lights out and early in morning at lights on to help keep plants ticking over. If i do this i will use around 4 to 5ml per litre of A&B and 1 or 2 drops of washing up liquid and i pay attention to undersides of leaves.

Temps may have summink to do with it as well if you get them higher that will help with take up more so 28c works or anything over 25c they should take up more feeds as it warms up and dont let temp drop too cold at nights below 20c if possible. Red stems tend to be caused by some kinda stress and cold is one cause of that which will also interfere with uptake of ferts too by roots.

Don't have fans blowing directly onto plants either

Whats your room temps ?
What ferts you using & feed strength ?
Grow medium ?

Room temps are about 25 on to 18 lights off
I'm using biobizz organic
And medium os canna terra Pro

The. One I revegged I didn't add perlite and yes looks soggy
Iv tried a few feeds at 10 ml per litre no nute burn but it could of led to the others being so dark .
The foliar feeding I like it I will try it
I also ordered cana term vega for veging ... I want to flip but with them not being fully healthy ...

I like some of your ideas
Also the fan has been blowing on the oscillating...

I will do follow your guidance as it sou do the closest as to what's going on thank you.
Iv been at this 7 years plus 4/5 tines a year or more at some tines when I did staggered veging ..
You thibk you no it all but .... maybe not ..thanks.
Any other tips but in the meantime foliar feed .

Im not most clued with organics but if i was a betting man id say its summink to do with lack of microlife in your medium and its probably well depleted so not enough of your organic ferts are being broken down for plant to take up to feed it fast enough. Flushing through the organic mediums is a no no really and that will have really depleted your microlife in their. You need to look at topping it up somehow, look for "microlife additives" for soil that top them up trichoderma and humic acids come to mind but their should be more if you look.

Adding sugars to your fert mix and bubbling it a few days with an airstone will also help break down your organic ferts before you even feed as it will also help top up your microlife. You will notice bubbling ferts this way will become foamy on top thats just bacteria coming to life and all good breaking down organic matter. But yes im not best clued on organics, i think you may find it hard to get back though unless you can replenish life back in to your soil. Simple white table sugar should do trick around 1t-spoon per ltr, but any simple carbs should help like glucose, sucrose , fructose, even more complex carbs molasses should help although its not instant and needs breaking down firstly hence why use simple carbs they wll help shit come to life much quicker. Don't take this as holy bible cus im no organic typo grower but tis what id do to try and sort problem out.

Using fert salts is much easier and a lot less problems cus plant can use feeds straight away so it doesnt matter about microlife in your medium. Thats an option if your not set on growing organically which is a much more daunting prospect imo.

I grow N.F.T. but what I'm not seeing here is any mention of Ph or E.C. Without a pH meter and E.C. meter, and a basic understanding of their workings, you're always going to be playing the 'guessing game' when you get problems.
