Nutrient burn/nitrogen toxicity?
Tubington9
started grow question 4y ago
I seem to be experiencing nutrient burn and nitrogen toxicity, is this fixed by just flushing with PH’d water for the next couple feedings?

What may caused the issues
Checked the runoff and confirmed 6.2PH and 130 ppm on water. checked on my Tank and same was happening. so gave a 603 ppm solution of cal/mag. Grow A+B perfect pH connoisseur, H2O2 at 5.8 pH. Will await for results. i think at week 3 theyre supposed to eat at least 600 ppm?

What is your best advice for helping plants look great and not dried out on any edges?
Brown edges got me down. I'm sure its just humidity. I've been adjusting the light. Could it be more? whats your best seasoned advice to keep those edges looking crispy... (Good) ? not in the wrong way!

Yellowing leaf tips
I have slight yellowing tint on the edge of a few leaves closer to the top of the plant. I am using 1/4 strength big bud and 1/4 strength bud candy. My light was about 18 inches from the canopy so I raised it to about 26-28 inches above canopy. Do you think this is light burn?

Unser erster Grow! Wir haben Nährstoffbrand, wie schlimm? Was können wir noch tun? - Dünger: Canna Terra Vega - Erde: COMPO SANA Qualitäts Eerde - 50%
Vor genau einer Woche haben wir einen Nährstoffbrand festgestellt. Die Symptome waren zunächst eher schwach, mit einzelnen, gelb hängenden Spitzen. Nun sieht es so aus wie auf den Bildern. Haben bereits im nächsten Guss ohne Dünger mit ph 6,3 Wasser gegossen. Was noch tun?

Leave Burn or Disease?
Can someone tell me what this is? Looks like the leave is burned (maybe water on the leave did that?) It looks like it’s causing the plant to grow way slower.

I don't think this is nute burn...
So I thought I had a case of mild nute burn but I haven't given the plants any Bloom or Calmag since last Friday, only water so I'm wondering if this is a nute burn issue now. Could it be my PH? Last I tested my run off it was at about 6.65. What's causing this?

Lower leaves yellowing and wilting quickly
Soooo Just went to water this beautiful lady and as you can see from the pictures 2 days ago and she was healthy. So this evening i found that the lower large fan leaves and the smaller fan leaves on bud sites are drooping and yellowing. This looks like its nitrogen or lockout?

Is this heat light burn? HPS 600w at 20cm
Is this light heat burn?? These are all buds at the top of the canopy and they are the ones nearer to the lights. I have 2x600w HPS, one with a cooltube and the other just with the wing. The possibly burnt buds are the ones under the wing (just 20 cm).

many problems with the leaves
the leaves have been turning yellow and falling faster and faster, especially those below; the upper ones curl and become burnt with dots and turn yellow should I try to put the lamp higher? (I haven't given fertilizers for a week)

Nitrogen toxicity??
Does this look like nitrogen toxicity to you guys? I have fed them only a little fish mix but I added some humus (worm castings) to soil when they got re potted and maybe too much? There’s no claw but the plant is dark green and tips are starting to go. I have flushed any ideas??
