Nute burn with low ppm runoff??
Ezzjaybruhanswered grow question 4y ago
Having significantly lower runoff than input, as well as higher pH from run off seems like it’s hungry personally.
Something is almost immediately displacing that feed and spiking the pH.
So it could be the roots are hungry and quickly up taking the feed, or the coco could be stealing some of the feed if not properly buffered.
When the dissolved salts in the feed are immediately displaced, this causes the pH to go up because most nutrients are slightly acidic.
I know it’s weird you have slightly burnt tips but that’s my best guess is up the feed a bit, or double frequency of feeds..

Saw this first day of 12/12Pretty sure this is just where I got nutrient solution on my plant yesterday when watering unless it's something else? I pulled these leaves off 1 plant when lights came on this morning. Every Plant looks 💯 great besides these 3 leaves, all from 1 plant rest of plant is great.Leaves. Edges burnt

Yellow and fragile leaves 2 weekCouple leaves yellowing and bit curved up. I suggest there can be the options: 1) magnesium deficiency; 2) nitrogen deficiency; 3) Light burn.
For case it is magnesium deficiency I sprayed the leaves with magnesium sulfate (solution - 1g per 1 liter), but it won't help.Leaves. Edges burnt

Cant find pH section. Leaf edges are burnt. Working on a student budget, had to postpone buying pH meter. Local tabwater is 7,03 - 7,74 according to internet. Ill be adjusting pH starting Thursday. Can I go to 6.0 straight away or should I go down in steps of say 0.2 to adaptWeek 5

Is my plant giving a warningI'm not sure if I have a problem or it's normal. Some tips show damage I think it was the light to close so I moved it back over 12 inches away. I am giving the bloom every other day but half of the water i give. No nitrogen is being given,hardly any ever she doesn't like it.Week 6

Leaf damage and flower analysisAsking for thoughts on leaf damage. I think there may be nutrient shock so I will be reducing PPM to 800 to see if that helps. I am confused by other problems seen on a few leaves. I also want to ask if I am getting close to harvest (check flower pics) since this is an autoflower6y ago
