Help me to diagnose

[Zaxar]

Hello friends!

My plants are about 2 month old, growing under cfl.
About 2 weeks ago this started on leaves. (I have 2 plants)

It started with lower leaves and going on upper ones. On the first plant first 2-3 leaves are totally destroyed so I cut them.
I'm giving nutrients on every other day. I know I have to check PH, but unfortunately I cant get one for this moment.

any ideas?
thanks

Hopefully someone will be along shortly to help you but the ph thing. You gotta do it. Cheapest way is pool test kit. It'll get you close enough. If you know someone with a pool it's free!

Zaxar you say you water every 2 days how much do you water? I think it might be your not letting them dry out before the next watering I use a moistier/ph (about 15 bucks) meter and let it go until its almost in the dry zone. I give my plants the same amount each watering.you can also do the knuckle test (stick you finger in the dirt up to the second knuckle if its damp dont water). did you check the GWE troubleshooting section,lots of good pictures to compare, good luck

Zaxar the ph thing really needs to be done Jeg is right on that .I would say that is the most important thing to get for you right now ( I got some pool test strips 50 for under $10 at Lowes they will get you started

thanks oldjarhead100

I mean I water them with nutrients on every second watering
I see I defiantly need PH meter...

the cheapest one in my local store is first one (about 15$)
Second one cost about 30$

will it make huge difference if I buy fist?

First one is what I use for moisture level only. The light and ph meter on it not so much. Still use red phenol pool drops for ph mine were free but $5 maybe

Unless your gonna spend about 100 bucks on a ph meter then just get the drops... any cheap ph meter doesn t work for shit.. i had 2 ofem before I said screw it an got a bluelab... should have gotten it from the start.. the drops are pretty dam accurate tbh

 

[Insight]

Which Bluelab are you using? There are a few different models.
Thanks

 

[Zaxar]

Sorry for this noob question, but will water ph tester (for pools etc) will also measure ph in soil?

P.S. can someone give me the link of some cheap ph testers on amazon?

[Zaxar]

Thanks Blazed227

But its too expansive for me

 

[Jeg]

Checking soil ph isn't as important to me as checking ph of water before you put it in and after it comes out. Those two factors kept in check will fix a lot of problems. And yes a cheap bottle of ph test drops is all I needed to grow my plant. It did decent, nice little buds!

He says he gives them nutes every second day - that's your answer Zaxar - it's nute burn

 

[Zaxar]

another noob question :silly:

Until i get testers, will flushing with for example 7.0 ph ed water help the situation?

 

[Canuck147]

Let them dry out between waterings - give plain water as well

 

[Burny]

Look for ph-009 on Amazon.

 

[Jeg]

Now that's something in my price range! Thanks. Does it work well?

 

[Burny]

Probably about as good as you can get for that price range.

The situation is getting worse
The dark spots moves to other leaves very rapidly.

Today im going to check all my local gardeb stores if I can find ph testers. If i cant i have to order it on amazon and delivery needs about 2 weeks to arrive in my country. hope my plants wont't die on that period :sad-frown:
