My feeding strenght is at 2.7 EC

From the point of starting my seeds I gave them nutrients with an EC value of 0.6 and then started increasing EC by 0.2 after every week has passed.

10 weeks and few days have now passed and yesterday I increased EC from 2.6 to 2.7

Now, today is the first day of me getting the symptoms of over fertilization - over abundance of nutrients.

Symptoms are very light - 25% of the plants are showing some clawing and very slight burning of the leaf tips.

What is freaking me out now is that one experienced grower told me he has never even came close to that strenght of nutrient solution and I don't understand exactly what's happening.

Why are they still so good looking then?

I'm not sure about how should I proceed...

Back off by 0.2 EC for a bit and continue doing my thing?

This is how they looked yesterday:

Please help. I'm really worried.

Good troll.

Nice plants!

I'm not trolling. I just have many eggs in one basket and it's all starting to get out of my control.

I don't understand the logic behind FEEDING.

I've been testing the run-off for few last times when I watered and the run-off comes out 0.9 EC less than I'm putting in ---> IN = 2.0 EC & OUT = 1.1 EC

Then I figured I should increase input and so I did for +0.4 EC

I upped my feeding strenght from 2.0 to 2.4 EC to see if the run-off gets closer to the input, but it didn't. In fact it still remained to be 0.9 EC less than I put in, so it was 1.5 EC this time.

Then I got told that measuring run-off immediately after it goes through coco coir doesn't give adequate results and instead I should look up to a way of accurate measuring by the keyword of "1:1,5 extraction method with distilled water".

I tried researching about this, but information that I came up with said that it takes 3 weeks to get the measurements.

Now I'm simply confused and I feel like I have no idea how to feed my plants.

As if it's a game of luck. No logic what so ever.

Today they look good, but few weeks later they might as well be dead.

I've been reading about how to spot symptoms of deficiency and over abundance in order to know how to keep the strength of my feeding solution at the right amount, but honestly, every fucking compound is connected to other compounds in a way unknown to me and if something gets over abundant, it could lock up something else and if that gets locked up, then it leads to deficiency and deficiency could show up very similar to as if it's not really deficiency but instead an over abundance... and ect.

Nonsense. I'm lost.

But it's probably not the best idea to start asking for a help here, because I will quickly get labeled as rude and troll and what not.

Ok, sorry. Never mind. I have calmed down now.

I just don't want this to escalate and I'm hoping to find myself an experience grower or "friend" whom I could direct my questions to, because at the moment I have only one person who's helping me out with great information, but he has lots of things to do in his own life as well and I feel that I'm bombarring him with different questions and there might just be too many of them.

Nothing in my life is more important for me than finishing this grow operation successfully, because my future depends entirely on the results of it.

People often fuck things up really bad at their first go, but I don't wanna.

some plants I have a swear I could dump straight floranova in the pot and they wont burn...now I think those strains have a happy spot and sometimes just cause they can take it doesn't mean they should..

nice looking setup btw.

Oh, I see. Their growth seem to be stunted btw, but I'm not sure what's causing this. It happened right after snapping them though. I figured it's because of that.

The biggest mystery for me still remains to be feeding correctly.

Sorry Helmut, I did not realize this was your first go! Most first timers don't go so big so I assumed you were stoned and trolling. You're doing fine, your plants look great!

You are correct that feeding does get confusing because over-feeding can cause lockout that presents as a deficiency. When you bring your nutes up in a controlled manner like you have done, you usually get warning signs of when you are getting to the max nutrient level your plant can take; Different strains can handle wildly different nutrient loads so knowing how to read your plants is the key, but it takes time to get a feel for it.

I could not see any downward hooked tips in your photos, but this is often how plants first express that they are being overfed. If you are seeing this, it is time to stop increasing your nutes and maybe add an extra watering only cycle. I would also take the EC down by 0.2 to 0.4 until the leaves flatten out again.

I look at the shine on the bottom fan leaves to know when they are getting hungry. When the shine comes off those leaves, the plant is beginning to take nutrients from the leaves so this is my signal to feed them or increase the feed rate. Once I am into flowering I don't pay as much attention to the bottom fan leaves and focus more on what the upper fan leaves are doing.

So if my leaves are nice and flat and shiny, I proceed like you have done, slowly working the nute level up.

If you ever get into organics, the feeding gets really easy. All the work comes on the front end getting your soils built up correctly and composted. Then you plants decide what to eat and when to eat. Nothing to think or guess about!

Keep the faith, brother, you gotta good grow going!
