Brown black spot crispy edges
lovely_neighboursstarted grow question 3y ago
I need help! Northern Light has Reddish brown spots turning dark-gray and crispy dark edges on the top leaves! It looks like a different issue from week 6 where gray spots appeared on the bottom leaves? Any ideas? Thanks

Looks like you have or had a calcium deficiency. When you grow under led lights the plants need more calcium. Best of luck the rest of the way.

Brown dark spots on fan leafAny clue what this is? It only appeared on 1 of the plants and only on 1 of the fan leaves. The brown color has kind of a metallic shine to it. My guess is that it’s a Cal. def. I also suspect it might be a Phosphorus def. as the plants turned dark green the last few days.

I don't think this is nute burn...So I thought I had a case of mild nute burn but I haven't given the plants any Bloom or Calmag since last Friday, only water so I'm wondering if this is a nute burn issue now. Could it be my PH? Last I tested my run off it was at about 6.65. What's causing this?

Problem with front middle purple punch. Info provided(See description for more); Temp: 71-79.5F, RH: 46.1, DLI: 40-50(decreased today due to tacoing)This is an organic grow using Coast of Maine Organic plant food, and lobster meal. It appears to me that the plant has deficiencies for all the three major nutrients, or lockout, but today it is also showing what appears to be Calcium or Magnesium. I've been using castings too.

Saw a lot of yellowing in the flowers, not sure if its enough or too much nutrients, or not enough water or its a pest. I was suggested neem oil to get rid of the pest creating those white spots, any other suggestions about how to get her to look healthier and growing faster?Week 6

Lockout? Can I remedy this late in the game?I think this is more than a K deficiency. I think I'm getting lockout. And a lot of it. She's an auto-flower, and I grow hydroponically. Can I even remedy it at this point?

Top leaves turn dark and curl - What can I do?I've had Nitrogen and possible Cal/Mag deficiencies 2 weeks ago.
Mid last week I started noticing some burn a the tips, so i dialed nutrients back again.
By this weekend the tips of the leaves curled further and turned dark.
The rest still looks a bit pale, but buds look good.

FEEDING PISSHi, I've been feeding with piss mixed with water my plants (1/20 parts ratio). At beginning of flowering stage I started feeding them less piss and more Flora Bloom GHE for more K. Is it true there is ammonium in the piss? Is it bad for the plant?

Does anyone knows if should I flush the pot ahead of time to reduce nutrients levels?As you can see from last pic from week 6, I have used pre amended soil with 2.5 % of Nitrogen on dry mass. (sorry for the italian).
Should I flush the pot ahead of time in order to reduce nutrients level so to both solve the yellow tips problem and favour the flowering stage?5y ago

Spots on leavesHi. My plant started to develop brown dots on the leaves and its edges started to burn. This started happening about a week ago. What could be the problem? I water the plant every day and my run-off is around 1000ppm. The second plant without similar problems. Thanks!
