Likely potassium deficiency on one of my phenos? Can someone please confirm?
biologischNLstarted grow question 2 years ago
Looking at my plant pictures on 2nd of feb, #1 (plant on right) seems to have some sort of deficiency. Looks like potassium. For the record I dont use liquid nutes. Only dry organic amendments and I have not watered or top dressed in roughly 2 weeks.
Thank you in advance!

I would agree with potassium.
If you're using organics try and find a kelp extract or seaweed supplement, They tend to be high in K and are readily available.
Green sand is also an option for long term release but it takes its time.
Wood ash is also an option at aorund 0-1-3 but it will make the soil alkaline.
Best Of Luck!

Slight Leaf Discoloration. Early zinc deficiency?Girl showing slight discoloration on newer leaves. Mostly interveinal + little on the tips. Guessing it's an early zinc def. but would like another opinion. Watering sparingly at ph 6.3 - 6.5. No runoff yet, so ph may be higher in soil. Lower ph and watering til runoff next time?

Strange discolorationThe plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.

Deficiency and assimetric developmentMy girls seem to have a deficiency, strangely enough, the gal with the most signs of deficiency is doing the best in bud production. Any ideas on what is going on here and what is the cause of the deficiency?
There is also some purple on the stema year ago

Yellow centre veins fan leavesYellowing of the inner vein of fan leaves only. Also sporadic yellowing and blemishes of whole fan leaves but only some, others fine nice and green. All bud leaves and buds don't appear affected. Is it just that she's nearing the end of her life cycle? Or over water/over nute?

What to do? Where am I at now actually? I’m lost and slightly discouragedWhen should I add happy frog fruit and bloom? This is my 3rd grow and im 0-2! I have a overfeeding problem but I’ve learned to be corrective and precise with ph and ppm and be pest preventative as well (heavy handed waterer as well..im trying). It’s day 5 of flower and I’m lost

Missing nutrients high phI put my moisture/light/pH thing in the soil and it is high in alkaline. We have a lot of Alkaline in our water here. Soil is made out on my growers farm. She has grown for 30yrs now. Never had these problems till this year. What can I use to compensate and bring the ph down?

Still to early to tell? Noticed yesterday and have slightly worsened today. Not sure the issue but potentially magnesium? Getting close to top dress also.Only on 1 of 3 plants so far. On older growth after getting dose of Recharge the other day. Maybe an N problem as I also use 484? Or mag? Using CalMag every other watering in RO at 150ppm as the soil has some cal and mag. Also getting close to top dress time maybe something else?

3 week old Skittles plantThis is one of my skittles plants I'm growing right now. One of the leaves on her started getting lighter spots near the veins. It is only a little right now but I am wondering if there could be an issue that I could solve before it gets worse.

Veins turning light green on lower leavesOne of my plants is getting light green veins on the lower leaves. Is this magnesium deficiency? I can't water currently without risking overwatering, can I just foliar spray BioBizz cal mag to temporarily help recovery? Or is this something else entirely?

White/Yellow snipes on leaves? (13th day of growth from seed)I noticed a huge change in my plant leaves in less than 24 hours. The leaves look like they are getting burned out. What is happening? I'm uploading pictures to see the problem and also the growth conditions.
I'm watering once every 1 or 2 days (PH = 6.0). Not using nutrients yet

Light cloudy green areas between veinsHi,
Two of my plants (3rd week of veg) have these symptoms on the middle level fan leaves (the biggest ones). Young growth looks ok. Doesn't look like anything in symptoms photos, closest thing is magnesium deficiency. What do You think it could be?
