Hello! All of my plants are suffering from bright yellow spots on their new growth. I think maybe I used toon little nutrients, 0.3ml/l of power roots and alga grow. I upped it to 1ml/l each but now I’m scared it’s too much? Please let me known if you have any advice!

several macronutrient deficiencies can cause this so without full details you only know about how she is being treated.

Three of your other grows I looked at were doing the same thing. Your using custom soil so I can't really be specific but looks like nitrogen deficiency. First and foremost is providing her with the proper growing conditions and when you use custom soil you need to be on your A game. I like to keep it simple when I grow

This looks like variegation... was it growing out like that or did it progress.. if just static pigmentation issues, it's variegation. it's a really weird progression , otherwise. maybe sulfur or one of the trace elements? looks more like variegation to me, though.

The recommended dosage is 4 ml Alga Grow per liter water (1:250). So I wouldn't expect it to bring such a reaction, Ec is within range as there is no dmg on tips, osmosis doesn't give you a choice, doesn't mean the ratio isn't skewed though on something, hmmm Alga grow NPK is 4:2:4, not recommended for veg tbh try stick to something more 3:1:1 or 4:2:1, excess potassium can cause problems as it blocks absorption of calcium, magnesium, and iron. The yellowing from the inside out looks similar to K toxicity. Possible but not sure, PH would help. Good luck.

Hi ja es kann an Anzeichen von Mangel an mikronähratoffe, ins besondere Eisen und Mangan, Stickstoff kann man ausschließen diese beginnt von unten da die Pflanze diesen aus dem alte Blätter zieht und in die neuen verlagert. Also ist das etwas erhöhen der dosis in Ordnung. Was du machen must um eine überdüngung zu vermeiden ist erstmal die Nährstoff Lösung messen der PH wert solte Stimmen und so bei 6 liege und der EC wert nich mehr als 1.4 haben. Wenn das paßt dann Messe als nächstes den runoff, also den Abfluss aus dem Topf der solte ein PH Wert zwischen 5.8 bis 6.5 haben der ec wert in diesem stadium nicht mehr als 1.8 Wenn das paßt kannst du sie mit dünger versorgen. Am besten schaust du dir ein Tutorial an wie mann nach EC wert düngt, wenn du das beherrscht dann kannst du fast nicht falsch düngen. Ausser die Geräte sind defekt oder nicht kalibriert.
