Is this a N deficiency?

So a few days ago I started getting a lot of brown spots on my fan leaves. I decided go flush and give cal mag but now it’s even worse. It’s still really wet but what I’m reading it looks like nitrogen deficiency? Its affecting tip and bottom leaves. Thanks for any help.

It looked very healthy a week ago and I’ve fed tiger bloom every other water.

Soil is happy frog. I always check ph of water. Temp around 74 humidty 50. Ppm around 1000 on runoff. GG4 autoflower. Cloth pots. Lights are 2 california lightworks solar extreme 500s. Ventilation is great, plenty of air moving.

A lot of those leaves look like they have too much nitrogen. Let’s ask @Myfriendis410, cause I don’t know.

Thank you. I use half dose nutes but maybe it’s still too much.

Once that far into flowering they are done putting up foliage really don’t need much nitrogen at all.

Just not sure what to do. I flushed with sledgehammer but didnt give anything but cal mag.

Ya your right I dont think I meant nitrogen cant remember what it was lol. Tiger bloom has almost 0 nitrogen.

I usually feed half strength Grow Big the first 2 weeks into flower and then cut it off and go with light kelp for the rest of the grow. I usually go by the color of my leaves and adjust according to what they look like.

Something is going on. I just don’t know what it is.

Yeah its got me stumped. Now all my other plants look good but one other one is getting some brown spots on its leaves kind of like this one did at first so I’m wondering if it could be ph related or something.

Phosphorus is what I was thinking not sure why I put nitrogen lol.

I think I have to to much cal and locked out the P. Now the question is flush it again since i only just did yesterday and its still really wet. Flush then water with tiger bloom since it’s high P or let it dry out then do it? Afraid at this rate its gonna be a mess if I wait 3 or 4 days

Please fill out the Support Ticket. Add some overall pictures of your plant and please be specific.

This doesn’t help. Details please if you want some help.

I did answer just about everything on the form and if ya read up a bit higher I said I meant P not N. I’ll snap a few more pics soon. Thanks!

This was about a week ago.

One last note I’ve been using well water (before softener) with about 170 ppm out of the tap. I am going to start using my RO always now just incase something in the well water is throwing things off. Hasnt been a problem until recently but never know.

Looks to me like a phosphorus deficiency. Dark green leaves the spots and curling . A P deficiency will make the leaves most exposed to the lights very heat intolerant. Is your under growth seeing any spots or curling ?
