safe newboydanny to me it looks like your plants are suffering a zinc def,the pale green between the veins is a dead give away.I dont no about your ph issues all i'd say is try a different supplier for your ph down.Try spraying the leaves carefully with some weak nutes wich has zinc in it but be carefull not to get the buds.Good luck with your grow.

Hey Danny Welcome to RIU.

OK an easier way to make sure your testing your pH is to collect the first few drops of runoff out of your pots and test this. That will give you a pretty true testing of whats happening in the root zone.

I dont like testing the soil using probes etc. OK for Moisture meters but not guaranteed for pH.

Once you have tested your pH coming out then you make the decision on how you combat it.

IF it is higher or lower than you want it to be i would mix up 3 times your pot size of pH'd water (with no nutes) SO if you are using a 5litre pot then you need 15litres of water. pH this water to 6-6.5 and flush the hell out of your plants. Then mix up a balanced nutrient solution that is pH'd at 6-6.5 and give them a feed after you have flushed.

This should help your situation.

10litre at a time is not going to cut it if you are in a 3gallon thats around a 11litre pot meaning you would need 30litres at least.

Is the 10litres allowing for sitting it out for 24hours too? I currently have 46 litre capability of water holding 2x18litre water dispenser bottles and 2x5litre water bottles.

You will need more water! GO out and buy a water container large enough approx 30 litres. Or if you have an old waste bin around your home clean it bleach it and fill it with water!

SO to recap you are going to need approx 30litres of water. pH the water down to 6-6.5 and run the whole lot through the plant and then straight after give it a feed so that it has some nutes back in the medium.

This is the order to which you should be doing things

1 mix your nutes into your water
2 test the pH
3 Correct the pH
4 Allow nutrient solution to stand for 30mins to 1hour
5 Test pH and correct.

wow thats a lot of water mate.so how much should feed them after flushing.im using ionic bloom and boost i put 70ml of bloom to evry 10 littres of water and 1 ml of boost to 10 to.so do i have that or full strength nutes

Hey Dan, are you using something like that to measure soils pH? Because I did, it showed around 7 most of the time but my plants suffered. Thinking my soil was alkaline i was pumping acidic water with every watering and my plants were only getting worse - until i checked the runoff pH - it was around 4!! Only later on I found out that, like jondamon already said, those probes are ok for moisture but with pH its a lottery depending on type of soil you have(it worked pretty well for a friend of mine, didnt work for me). Good luck!

You maybe better off just using your IONIC grow with the BOOST as it has more N in it for the plants to be happier.

I used to use IONIC but didnt like how yellow my plant became during flowering so i switched to canna coco a and b
