Im watering 250ml a day and using only water with nutes. Should i also use plain water?

I am scared to water till run off as they are young so if they are in big pots roots wont breath.

What do you think?

They look very dry IMO.

I prefer to water around the plant. Make the roots search outwards.

I don’t think you premoistened the coco? It all looks very dry.

You made sure your PH pen is working too? I'm just assuming here but I guess you bought both of them for cheap of Amazon or eBay? I would calibrate it as that seems a lot of food for the size and as others said, water around the plant in a ring make them roots find the water

Yeah I did but had PH problems before I had a pen. They were getting very acidic water ?? my fault.

Thanks for the support guys

You should be feeding no more than 0.3EC at pH 5.8 to your ladies with plenty of runoff.

**Adriaanoo** · 24-02-20, 01:38 PM

I know but I my tap water it self is 0.4, no way to get water filter now.

**Jumper114** · 24-02-20, 01:43 PM

Yeah, so your feed should 0.7. Then drop pH to 5.8.

there are online converters for Microsiemens tp ppm etc...
but a decent working ec pen can be bought for as cheap as $10 (offcourse not top notch quality )

Rhizotonic usually put my EC up so much.

Also with the run off thing, as the plant is small to you think it will drink this much water every 1-2 days or just wait until medium is dry and water again?

Sorry for asking too much questions, just want to get everything correct mate

You need to dilute your feed with water in order to achieve 0.7.

In coco you need to feed at least once a day to 20% total run off. Even for a young plant.

I feed mine every 2 hours to runoff.

Every 2 hours? Are you hand watering? How many ltr of water are you using per day then?
