problems with leaves

[hombrey]

hello guys,
troubles with users in forum were really not in the best time.
i have problems with these two plants, one is only clawed up as you can see, the other one is in flowering, and i thought it was light burn, but i don't think so anymore, can't figure out what's the problem.

picture 1 - i have this burned leaf maybe someone knows what this can be?

picture 2 - clawed up leafs, my temperature in room is fine, and humidity either, it's not the climate, because one other plant is doing really fine, just had some magnesium deficiency.

picture 3 and 4 - that's what i thought was light burn, but it's not, can it be nutrient burn ?

please help me if you can, thanks a lot in advance.

ps. i gave em some calcium nitrate and magnesium some time ago, along with my biobizz nutes, i've been using fish mix, bloom and grow now.

Hombrey welcome to the AFN........ If I might ask what is your ph at ..And check out the , Cannabis Infirmary alot of good info...

Do you know what your soil ph is? I believe that is some magnesium issues. Have you had a look under the leaves where the rust spots are.? I dont think it could be, but do you have any mites eating in that area.. First thing definitely is to check the soil ph if you havent already. Hopefully someone with alittle more knowledge will chime in for you. Much Luck and hope she gets to better health. Stay positive about her.

ph is at 6.4 - 6.3, and it can really be magnesium, i gave her minimum strength what was said on epsom salts, but that can be too much right? thx for fast answers
it's really hard to understand something from google and this forum pictures about nutrient burns, toxicities and stuff, ehh.

soil ph is imprtant and without a good probe it's hard to tell, but there is away. water with ph'd water till you get 10% run off, then check the ph of your run off... Here's some info

PH - The Manual

Rough Calculation Guide:

Here's some good info on ph.....
If your runoff pH is higher than your starting pH, use this equation to determine your soil pH:*
Soil pH = Runoff pH + Difference

If your runoff pH is lower than your starting pH, us this equation:
Soil pH = Runoff pH - Difference.

For example, say your the starting pH of your solution before it goes in is 6.5 and the pH of your runoff is 7.0. The difference is +0.5, so using the above equation:
Soil pH = 7.0 + 0.5*
Soil pH = 7.5

If your starting pH is 6.5 and your runoff is 6.0, your difference is -0.5 and using the above equation:
Soil pH = 6.0 - 0.5
Soil pH = 5.5

Good stuff Goauto,:thumbs: hombrey you want visualz, you can always count on goauto.
I hope all works out for ya bud. Keep it green

Also, if you fill out the troubleshooting request form from the Infirmary section, it'll give us the info we need to help diagnose your problems...I'm inclined to say pH as well, based on pot's soil pH requirements, it's really easy to lock out CaMg if you're in the mid to high 5's.
