Ph too high or low?? Cant buy a meter, plant very sick. In soil

[agito]

reverse osmosis
i would give them more you want plenty of water to wash out of the bottom

How much more? I put another 1.2 litres through there.
Here they are being flushed, the one on the right is Polar Light 2 and the one on the left is Automazar.

The fourth phot across is the head of AutoMazar, see the way the leaves are thin and windy? Is that the same problem? Cus the 3rd photo in is on of two leaves on the AutoMazar that has been affected by the brown spots

 

[agito]

i would say it was the same problem
on the flush just put enough throug until your happy the nutes have passed out, signs of colour in run of if your pots are 6.5l i would aim for more than that

 

[Autolove]

So I should keep going till no more color in the run? cause the run is a darkish brown last time i checked

Do you think my polarlight is saveable? If the situation doesnt get better would it be best to cut her and dry her or is she too young?

 

[agito]

i would add more water
you will have to give them time to recover before you can tell 7-10 days

Based on the pictures should I be pruning yet?

 

[agito]

you dont prune a plant in flower you can remove leafs with more than 50% damaged

Save your money on that pH meter. Those type are notoriously inaccurate. Take that money and put it toward a good one. Don't know what is available in your country but something like a Control Wizard Accurate 8 for soil or a Hanna for liquid.

Also, learn to water your plants by weight. Get a feel for them when they are dry and only water when they feel that weight. Depending on your lights, soil, humidity, etc. that should be about every 3-4 days. Also with autos it's best to start feeding 1/4 strength nutrients and slowly work your way up. Looks to me like you're given them too much water and nutrients.
