maelxichstarted grow question 3 years ago
Last week she started lightly fading yellow on a few of the smaller, lower leaves. I saw claw down leaves and figured N tox so I did ph 6.5 only for a few waterings. Now she’s turning totally yellow with some burn marks. Not sure what happened or what to do!

Well what I see is you did have a nitrogen toxicity issues starring but you stopped it. She will still use a little nitrogen in flowering. Mainly they want potassium and phosphorus. Flowering npk ratio is 1-2-3. Just you cut back too much on the nitrogen. So I would reapply some in next feed, and also test run off ph. Make sure your substrate ph is still in range. Good luck and happy growing 🌱

Hi there Mael , yeah so you're right about N-related issues. you can tell from the yellowing starting with the oldest leafs first. The plant is cannabalising itself for N. It's a deficiency because you're only adding N with "other" things like in the calmag and so on. usually you do want to keep adding N even in flower , just careful with the NPK you want to keep it going for flowering so something like 2-4-4 , the main idea being twice the PK as the N. If you dont fix it it will get worse, but if you do the problem should stop spreading and it will be smooth sailing from there on. Hope this helps ! 🚀

Será uma deficiência de cobre?Ola, sem ser a questão que já não consigo subir mais os leds e as plantas já estão a mostrar sinais de stress por causa da luz.
Agora apareceu me uma das plantas assim, com as pontas amarelas mas a ficar maior.
Fiz um flush para limpar, pois penso que seja nutrientes a mais.

Purple stems-curling tips leaves point downGuys the sides stems seem really purple!even the central stem..
Why? magnesium deficiency?or genetics?
And that leaves tip pointed down; they are a problem..
Maybe N deficiency?(due the early preflowering for the wrong light cycle) Thanks :)

High TDS and low ph runoff - Lockout? deficiency?Struggling with some bad soil (beginners mistake). I water with dechlorinated tap water at around ph 7.4 and 400ppm (not feeding yet). But runoff ph is 6 and around 1000 ppm.
Am I dealing with a N-lockout? why such a ph difference and high TDS value?

WaterIs it bad to make my water ahead of time ? I mixed my nutrients (big bud, formulex, bud candy & molasses) in with the water & have let it sit out for over a day. I heard letting it sit out gets the chlorine out (I put a towel over it though so my cat/other stuff would get in it)

Liquid oxygenWould you all use this in your water when trying to give oxygen to the roots? I’m noticing some really dense, not drying up that quickly soil so it’s making me think that they can’t breath. I don’t know, just making sure every part of the plant is happy & healthy.
