Flush or wait?
eaf620
started grow question 5y ago
I suspect the ph is off. Should I flush it out with some balanced water or wait for it to dry up? On the bright side, my first attempt at hydroponics is going well!

great thing is you can replace entire reservoir... ensure it's pH'd and a proper balanced diet for plant.

Possible deficiency/humidity/pH problem
I've been struggling with same problem from beginning of grow - leaves having these dry yellow/white spots. The first week I used too high pH which later I replaced by rainwater - new leaves were healthy, but last night I left tent at 70% RH. Somehow it returned - still rainwater

Dying leaves
I think it's a nitrogen deficiency causing me to lose some leaves earlier than I hoped, What should I carry on doing from now on? Last watering was 0.5ml/l of Grow, 2ml of bloom and 1ml of CalMag, just recently fixing a calmag deficiency after not having any(ran out).

orange sherbet crispy leaves. Close to harvest
Fastbuds Orange sherbet first grow. I already harvested this plant but I’m curious what the issue was. The leaves were yellow and crispy to the touch. Other leaves looked fine. 2.5oz harvest but it dried really fast(7 days) and now smokes harsh. Don’t want to repeat this mistake.

Yellow new foliage
From my research it could be phosphorus toxicity, iron deficiency or sulfur deficiency. Or it could be over watering. Or it could be poor drainage. Or it could be light deficiency (I have a 42watt Tled with some led strips until Mars 600 arrives)

Carences ?
Les veines des feuilles des Txerri Bilbo Haze deviennent légèrement bleues, est-ce une carence de phosphore ? Les feuilles de la Master Kush s'éclaircissent sur les bords, est-ce bien un manque d'oligo-éléments ?

When to start nutes
Anyone have any tips on when to start nutes on this girl? Her bottom single leaf is yellowing a bit and one or two other lower leaves have a yellow mottled coloring. Not sure if that’s from touching the soil due to LST or because she’s hungry. This is supposedly a low nute strain

Can this stretched seedling be saved?
So, my first seedling spent a few days w/weak light and got stretched. I then started “Shorty”; both outdoors the last three days. I buried “Stretch” 3/4” deeper. Is “Stretch” (the first plant) totally fucked? Anything else to do? 1st pic is Stretch, 2nd pic is Shorty.
