2 Plant Yellow tips, can you help? I habe no idea what to do.

PS getting runoff in soil can be a bad thing if your using amendments as it washes out all that's it broken down and it take more time to break more of it down. If you get a lot of runoff its essentially flushes the medium and makes it have low nutrients leading to issues.

They have changed their dosing recommendations over the years. It used to be up to 4tbsp/1gal of medium when mixing in and up to 2tbsp/1gal per top dress. Its now down to 3tbsp/1gal for premix and 1tbsp/1gal for top dress. I always find their 444 gives way to much N all at once vs spreading it out. And if your not digging it into medium when top dressing it form a hard later that becomes hydrophobic, but the digging can cause some big issues to the surface feeding roots. The plants look to be having issues with a micro nutrient. or craving some more Potassium. https://420life.com/wp-content/uploads/2021/10/Marijuana-Leaf-Deficiency-Chart-scaled.jpg Gaia makes a potassum additive called soluble seaweed extract. it looks like brown crystals and have good amount of K and some micros "i think". Another brand of similar products as something called Fresh seaweed concentrate and also has micros in it. Its by Acti-Sol under their Acaide lineup. cost point I think is about the same dose by dose, but the other comes in smaller sizes so don't spend as much up front. I have not had this issue with gaia before. so bit new to me. Also fix you lights. 24/0 is to much. plants need downtime. 18/6-16/8 is fine for autos and veg. 12/12 is good for flower. can also go by the DLI its outputting. Google DLI is its a new term. Wiki breaks it down nice. Nutshell. how much light over the course of a day 24hr in a single number format. Don't want to go over 35-40 for basic setups.
