Over feeding (10 different fertilizers!!!) and under watering has lead to o build up of nutrient salts in the substrate, causing this burning.
Watering to run off each time you irrigate is vital for overall health.
This is too far advnced and the plants too close to being ready, that there is nothing you can do to fix this before harvest time.
Had you asked this question 2-3 weeks ago when the problem probably first appeared, there may have been a chance to stop it getting worse, but now is too late.

Nitrogen deficiency but why?My Critical Auto is more and more wilting and yellowing. Most likely due to nitrogen deficiency. Some have red tips on . PH of soil was normal, how can I make sure that it's not nutrient lock anyway? Should I flush it nonetheless? Feed it more? More info in my diary.

Yellow lower leavesHello,
This is my first grow and now I'm confronted with the first problem.
The lower leaves on my plants are turning bright and yellow. A few leaves have very small brown spots. Can someone help me and perhaps have an idea as to how I should proceed? Thanks.

Can I use magnesium sulfate foliarly?Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect.
I should add Dolomite Limestone to the soil this week.

Yellowing sugar leaves?Does this yellowing on the sugar leaves look problematic? I know the end is near so I don’t want to do any damage this close to harvest. Think another week will be long enough?

Living soil and rain water problemHas using rain water killed my living soil?
Has anyone got experience of using living soil with rain water? Apparently the ppm is too low (just like RO water) for the plant to take in nutrients.
So basically is my living soil now just soil or is the microbial life still there?

Hojas bajas amarillasTras un día de sol sin un calor excesivo he detectado hojas amarillas en la parte baja de esta auto mutante (2 plantas de una semilla). La he alimentado con algunos ferilizantes, incluso calmag en una cantidad adecuada para la prevención... ¿Qué podría significar? ¿Como parece?

What can I do? Leafs starting to turn yellow. First growerYesterday, I noticed some leafs starting to turn yellow and also the tips of the top leafs to be a bit brown. So I watered (nutrition in the desc) and calmag 2 ml, because I thought it might be either lack of PK or cal mg. What else can I do? What about my watering schedule?
