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.

Is this light burn?All my leaf tips are going yellow, even on the bud leaves. It does seem to be a bit worse towards the top of the plant. Is this light burn? I am using 2x 1000w philzon LEDs in a 3.5'x3.5' Tent and I had them at 10/10 brightness. I just reduced to 8/10. Thanks in advanceLeaves. Color - Yellow

Ingiallimento fogliareSalve a tutti, sono nuovo membro del team, ho cominciato da 1 mese una coltura indoor. Da 2 settimane mi porto indietro un ingiallimento strano delle prime foglie di una autofiorente ma non capisco il problema dato che utilizzo un substrato concimato e scarti di caffè per azotoLeaves.

Day 38 autos: is this nitrogen deficiency or something cal mag could help with?Kia ora whanau,
Each of my three flowering autos (the Herbies Beginner Auto Mix #1: Ape Fruit Auto, Purple Chill Auto and Godzilla Cookies Auto) has an issue with yellowing older leaves. Do I need more nitrogen or is this potentially something cal mag would address? TYVMIA!Week 6

best leaf insects repellentI have found a few bad insects on my plants past weeks. Does anyone have experience with neem oil? Is it worth a try or would I be better of buying something else?
White vinegar with dishsoap didn't help much.

yellow spots on upper leaves, towards the end of flowering, I grow in a Coco ,flowering 8/10This is my second attempt at cocus
I work with Plagron nutrient solutions(Coco Nutrient)
I follow the table, there were no problems on my first try.. should i stop nutrients? I always mix the water in a bucket, so I can't spoil it either, because most of the plants are healthy, ph 5.5 is always between 5-7!Leaves. Edges burnt
