Hi mate please ignore the person that said to feed with pk13/14 at 1/8 and to feed, water, water then feed i remember listening to this advice over 10years ago when i started grower its literally spread from grower to grower just think of you as living organism just like a plant would you like to eat then fast then eat and fast plants dont either they always want food the problem is over feeding. For your first grow your doing great add pk at half strength if you like but cut back on tiger bloom when adding thats all keep an eye on your leafs if getting dark green feed little lighter as to not burn plants.
You should be proud really healthy plants keep up the good work 👍
