Problems with pH

[JainyGG]

Hey!!

I got some problems with my ph-level.
I feed water that has a ph of around 6.5 - 7.0, howevery the runoff has a ph level of <= 5.0

What can I do to fix that and first of all, what can cause this problem? I am using BioBizz AllMix. A solid soil what i read so far.

Is it causing problems with your plants? -granger

Add a bit of dolomitic limestone. This will slowly and safely increase the pH.

Sorry for the late response.
The plant isn't looking healthy, new growth looked okay until I watered it, a day later it they were looking bad already.
I gave them some very little BioBizz BigGrow for the first time ( after 2.5 weeks in veg) It was like 1ml on 2 liter water.

The pH is now at about 5.5 of the runoff.

Here are the pictures. Any ideas?

Ah, what i should add is that i topped her like 3 days ago, before i watered.

Give them 5 ml/ltr

Give them 5 ml/ltr

5ml of bio grow right? It's this stuff: http://www.biobizz.com/products/organic-fertilizers/bio-grow

should i wait with the watering until it's starting to get dry or water already?

Starting to get dry-yes. Wilting-no. -granger

Hey!

She is looking not as bad anymore. Granger2 or anyone who knows, should I continue to feed her with that 5ml/l BioGrow or should I lower the amount after the first watering with that amount of Bio Grow? I have to water tomorrow for the next time since I will leave them alone for 5 days. Is there a way to keep them moist for that long? They tend to need water like every 3 days, is there a way to extend the time they can go without water? Can i add water to the part where the runoff water gets into to get more days between every watering?

Thx!

You can try that, but it may not be enough to extend to 5 days. In general, not a good practice, but to do once in awhile, it may work. I'd stay with the 5 ml till the plants are thriving. Good luck. -granger

Get some Blumat Maxis drip irrigation the plant will water itself! Keeps the Perfect moisture level. Not hard to set it up either. I wish I would have known about them years ago.
