Yellow tip and leaves

Hi there Helpamamagrow , that's micronutrient-related issues , you can tell from the yellowing in between the veins of the leafs , affecting the newest growth first (immobile nutrient issues). Thing is, you're already adding micronutrients. So what happened is a lockout. that rarely happens but i see you're using two different micro nutrient feeds. that's likely too much. Unfortunately these things are quite difficult once they hit the soil in this way. You'll need a flush i'm afraid ! Water until run off , then water 40% more of that amount for a flush, make sure you avoid water stress / overwatering by timing your wet dry cycle. Then cut out one or the other micronutrient feed , and just keep doing what you're doing, because you're doing great besides this one minor thing. Consider keeping your veg a while longer to compesate for any stress, hey! Hope this helps ! 🚀
