Grow QuestionsNitrogen toxicity??

Nitrogen toxicity??

UncleRemusstarted grow question 5 years ago

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??

Looks like she needs other nutes. Worm casting and fish mixes has plenty of secondary nutrients. Lacking a bit in potassium but it is okay at vegging stage. Could be a lock out of K, Calcium, and magnesium. Adjust you pH up and you should be okay. Feed cal mag or lime solution to the soil, and you pH will goes up. Goes easy. Takes a couple of days before pH to go up. Quick fix woulb be spraying with one thrid strength of cal mag.

Hi there.. this looks like interveinal chlorosis of the leaves (it turns yellow, but the veins stay green). This usually isn't the case with normal nitrogen deficiencies, but is more of a magnesium, manganese, molybdenum or iron deficiency symptom. If iron deficiency, then the young leaves would show it from the stem outwards, but here it looks like all have it from the outside inwards, so would rule out iron. A magnesium deficiency often goes paired with rusty spots, so my best guess would be manganese. happy growing!

Leaves burned after spraying a cocktail To repel aphids I sprayed garlic infused in alcohol with water, already did this few times without side effects. But this time I added several drops of tea tree essential oil. Is it possible that the essential oil has burned the leaves so much or is this some nutrient deficiency?

Nute burn? How to handle?Hi, i guess i made the typical newbie mistake and over-feed a little bit. The plant started to get some brown/yellow tips, mostly the upper part of the plant. Is it enough to just stop with nutrients and stay with clear water or is there anything else i can/should do?

Week 8 (4 weeks into flowering) - Possible Nitrogen / Cal-Mag issue?Plants show signs of what i assume to be a deficiency. Stopped feeding nitrogen Week 7 according to schedule. Symptoms are not on every leaf but some the upper foliage. Yellowing, burnt tips and rusty spots. My guess is lack of Cal-Mag & Nitrogen. Is my guess correct?

Is this nutrient burn?As a beginner it is hard to classify that: Are the brown tips a sign for nutrient burn? Or rather a deficiency of something? Soil pH (out of whack) 7.4ish. Fighting that for weeks now... Soil EC ~ 2000 µS/cm. Crazy Hills fertilizer as scheduled. Thank you!

Nutrient lockout or deficiency Die unter Planze im Bild ist seit ein paar Tagen hell obwohl ich letztes mal schon mehr gedüngt hab. Habe mit EC 1.5 / Ph 6.2 gegossen. Im runoff kam Ec von 3.5 raus, es war aber nur sehr wenig runoff deswegen find ich 3.5 eigentlich in ordnung. Blatt spitzen sind aber auffällig.
