"Claw-Like" leaves and brown spotting????

almost 7 weeks into flower...my bud leaves are starting to "spot" brown areas and almost all of the upper leaves are showing "claw-like" symptoms. Any idea what could be causing this? I just flushed my soil today....or "leeched" rather....not a full flush.



....any advice would be super helpful...more of my info is here....https://www.rollitup.org/newbie-central/609785-1st-time-grow-just-looking.html

Heavy watering and excessive Nitrogen will do this !

thank you, so the fact that I just dumped a ton of water into her today means it will take a few days for her to bounce back? the soil was next to bone dry today....almost a whole finger into the soil was dry

If we can trust the color in your pictures then your leaves are very dark green, which would indicate too much N even without the claw. So it's a good thing you've flushed. And the drooping is probably due to overwatering as said before. I just had a similar problem with real N claw and that is hard to confuse with overwatering. It's too sad to even think about. Your plant will be fine, just go easy on the nutes once your soil is ready for watering again.

...at 7 weeks flowering should I even add nutes anymore? I figure I have about another 2-3 weeks left before harvest.....and thank you both for the replies.

Burn baby burn. I have heard of 2 week flushing 1 week being the norm but three weeks seems extreme and pushing luck. Just cut back on nutes a little for now.

Sounds good, I'll probably feed 1 or 2 more times with nutrients....then switch back to plain water.

Any thoughts on why there are the brown spots? It doesn't seem like those can be caused by overwatering, but perhaps too heavy on the nutes? I've only given 1/4 to 1/2 strength, but I have added nutes almost every time i"ve watered.

i would advise using no more nitogen, are you using bloom nutes with a high nitrogen? get like a 0-10-10

edit: after looking at the pictures more you for sure are using way to much nitrogen for flower and are stunting your flower growth, again, i wouldnt use any more nitrogen just add bloom nutes 2-3 more times then flush 2 weeks, looks like u have a little while to go still..

That's why I use a tensio meter on soil, else my plants look like that every other week or so. Best investement in grow tools I ever made.

Awesome, I'm using a bloom nutrient that is 15-30-15. I'll stop immediately. ....on my way out the door to get something with 0-(something)-(something)

Thank you so much!

Also, aside from the clawing symptoms, I am noticing multiple brown spots on my sugar leaves....both at the top of the plant and even some lower bud sites as well.........not all sites, but it does seem to be decreasing. ....will switching away from the higher nitrogen fix this as well? or am I looking at another problem?

Brown usually means necrotic (dead) tissue. It should stop once you get some fresh water in there and get the root zone healthy.

Not something commonly seen by most in the states . I kinda have a built in one from all the years of watering .. But maybe I ll get one sent over to test myself lol ....Peace

Oh I wasn't aware of that. The one from Blumat is pretty much standard here, even for (wise) low-budget starters. The more experienced often end up using 1 dedicated per pot. They are like 40-45usd here, but it will earn itself back and then some in a single run easily. Plenty of people get by lifting pots or using the ol' finger in soil, but overwatering is pretty much the nr 1 beginners mistake and often misinterpreted as (resulting) deficiencies. With a tensiometer water shortage or excessive water can be excluded quickly before adding water or worse nutes as many tend to do when their plants look like the OP's.

Also great for watering soil before planting seedlings.

That and you can get a fairy accurate idea of what the plant uses daily, and should use. Allowing you to spot problems sooner and keep vegging optimally (over and underwatering costs days).

And during flowering, when they really start to drink you'll know before the plant itself starts showing (which would be a little too late), same for later when they stop drinking.

I wasnt exaggerating either, it's truly the best investement I made. It's not used like a ph or tds meter (not as reliable) it's more like a learning tool to develop a better feeling for how much water plants need in different stages, and at the same time makes it easy to detect over/under watering, amd shows plants need water a night as well.

A near-cliche almost every beginner with a tensiometer notices is that till then they used to give waaaay too much water.

For future reference, if you do get one, safe yet rough values are 80-100 during vegging en 130-ish (=less humidity) during flowering. 50 is normal after watering, 0 means you drowned it, 300-400 means it needs water immediately. So if you water once a day you'd want it to drift from 50 to 100-200, if it says 250 the next day you'll know you can give more, if the value is still low you can skip watering or give what you think will result in a good number. It can take several hours for the reading to stabilize after watering.
