Hey Piece of advice please

[kosherkush]

Lately im starting to see this on my leafs, the picture i took of the worst looking leaf, some other leafs showing the first symptoms of this problem i guess.. its showing up first on the older leafs.

Looks like a little phosphorus deficiency or early signs of a pH lockout situation. To make a better determination we'll need more information. What medium are you growing in, what are you feeding, at what strength and how often? What is the pH of your nutrient feeds and the pH of your run off?

Hello,
Thanks for the support,

Medium: premium mix soil based on peat mixed with perlite+vermiculite+humus
Feeding: 12.5L Airpot, biobizz nutes week#4 of flowering
Heaven:4ml/L Grow:3ml/L Alg-a-Mic: 3ml/L bloom:3ml/L max:1ml/L

My water PH is pretty high around 7.5, when i mix the nutes ph reduced to 6. i dont often check/balance the PH since the soil always helped me out there.

I feed them 2Liters every 3-4Days ( when the soil is 80-85% dry)

Muddy is a wealth of knowledge, so learn as much as you can from him. He won't steer you wrong. Are you measuring your soil pH, too?
Here's a guide that usually comes in handy, when it comes to trying to narrow it down to what you might have. Take a look, and you'll see that it appears Muddy is most likely spot on.

THANKS for the link i blessed you a whole 10 minutes for that.. im not quite sure now either ph or root rot? how do i check my soil ph? i never done that before anyways i keep my ph always around 6.0-6.3.

Maybe muddy could help me figure that out i`ll wait for him to pass by and save my little paranoids day

The soil pH is always the place to start. If it's off, then adding additional nutrients won't help. If you don't have a soil probe to check it, then next time you water, given enough so some runs out the bottom of the pot. Check and record the pH of your feed, then check the pH of the water that runs out the bottom. Let us know what those readings are.

Hi kosherkush, It sounds like you are using a pH tester for liquids, no? To find the soil pH if you are, water your plant(s) so that you get runoff at the bottom (check the pH of the water going in-record it), then check the pH of the run off. These two pieces of info will help determine your soil's pH. If you can get those readings, it'll help verify if pH is a factor. To me, it could be pH and it also looks like some nute burn. Verifying the soil pH will prove or eliminate a big question mark. Best to you. And, as Bandit says, Muddy is an Oracle of knowledge, with great taste in blues music, apparently

It's the long one in the picture. HIGHLY recommended and very accurate. The Accurate 8 will become your best friend, trust me!

That's the meter i use, too. Bandit is right-its a vital tool in my grow areas. And I see Muddy and I posted simultaneously... lol Credit to Muddy- he taught me more about soil pH since being on AFN!
