Calcium issues?

scotch_eggstarted grow question 4y ago

Is this the start of a calcium deficiency? Aside from these couple of spots the plant looks healthy, but I really don't want this to progress. I can't measure my PH for a couple of days, sadly, until I get the equip through the post to do so.

The leaves look a bit dark, and I see some clawing, and some slight tip burn, so i'd say there is a bit too much Nitrogen. I would give her just plain water for a few waterings, and then start feeding your bloom nutrient at 1/2 strength and monitor the results. Happy growing.

Is your water quality hard or soft?

I'm not sure if it's cal or mag def, your plant looks overall very healthy so I wouldn't be surprised if your ph was on point. Looks to me more like nutrient water magnification burn. 🌱👍

There is some sorta spot things searing on the leaves of #2, I pulled the leaves that were effected. Only on this plant the other 2 are not effected. Ph issue? Stress issue from training?

I suspect I have either leaf septoria or a calcium deficiency. I'm 2 weeks from harvest. The top leaves appear to be affected. The smell has changed (sharper). Not sure what to do from here. All advice appreciated :)

Hi growdiaries, Got a couple of issues on my plants here. The last 4 pictures show the problems, firstly there are holes appearing in the leaves and it looks like something is eating them. Haven't seen anything alive. Also a few spots appearing. Mould? Had bad air for a bit.

Do my girls look healthy? There's small lighter green patches here and there and some leaf curl. I might be a over analyzing/reacting. I'm a little paranoid but autos supposed to be finicky and stunt easily, and can go from bad to worse very quickly, from everything I've read.Thx

Am I correct in diagnosing this as Calcium deficiency in the Black Sugar? I gave a basic compost tea yesterday. What else can I do to ensure she makes it through harvest?

Hiyo. Plz notice the 10/30 pics. Should be about 4 more weeks to harvest. I know she is going to start going off as we get closer but this is a couple weeks early for my liking. Any ideas? I water/feed with the basic fox farm trio. With 4 weeks left is it an issue? Thx.
