BurntTips and PH rises, who can help?

to flush the salts out water them until runoff then let them dry and recheck ph

@Grey_Wolf thanks, ok so now i flushed them with water to dilute the substrat. The next day i will feed only water, or i let it dry out first, because now its very wet all over? Is it better to feed 1 liter water and then let it dry out about 3-4 days and water/feeding again. or is it better to feed them little by little. I struggle of how much ml water i can give them

@Grey_Wolf thank you for your response. Yes, i use Advanced Nutrians PH perfect and I mix all Micro Grow Bloom 1ml/liter of water. And feeding every morning about 100ml Mix and evening/night 100ml Mix again. I try to give very little, the soil is lightly wet and overall airy. The PPM and EC is low or not? How can this little burn them? Normally this product should balance the "perfect" PH?

@WeedDude the burnt leaf tips are from nutrient burn Are you watering with feed every time? try flushing her through with plain water ph set at 6 then start over with your feeding regime
