Can anyone explain what is happening with my plants? new growth is kinda pale green/yellow on only half the leaf.

New growth at bottom affected too


Not as bad on this plant #2 but loos like early signs to me


Looks like it’s all new growth. They do have that lime green appearance when new and growing rapidly. They’ll darken a bit as they age and match the rest. @Lucc89

Thanks @Covertgrower I’ve been stressing about it for like two or 3 days now I didn’t notice that some of the older leave have gotten their regular color. But that bottom growth site doesn’t look like interveinal chlorosis to you? I instantly started searching and thought zinc but this is my first grow so I’ll leave it if that’s what you think.

Grab that runoff ph before doing anything drastic, check the ppm of runoff too. What are using to get your feed to 1450ppm?

@dbrn32 definitely gonna get it asap just watered yesterday should be ready tomorrow. And 3 tsp bloom 2 tsp grow big 1tsp cal mag 1tsp root enzyme up from 1.5 tsp bloom .75 grow big 1tsp calmag 1tsp root enzyme.

*Update runoff pH 6.37 (watered with 6.45) runoff ppms 818
