Okay

So I have a few leaves with this strange yellowing going on it's like 4 leaves. At all different levels. The photo is one at the top of the canopy. I'm worried it's a cal issue but maybe a mag issue? She's a auto rqs quick one in a 3 gallon ffof perlite mix nutes the trio from ff. She at the beginning of week 5 she is in preflower/flower. On a 18/8 light schedule, 24 inches from a 400w hps just switched over from a my light around the time the yellow patches started showing up. Could a be light issue from the switch? The lighting is cooled with a 6 in 440 cfm inline fan. I did switch to flower nutes his week soil schedule from ff. I have not seen any nute burn on any of the tips of the leaves!

Using tap water which has cal in it

And if so then yes it's most likely due to the switch. Not much to worry about. Raise the light more if it continues and acclimate it to the light slowly. It looks very minimal I wouldn't worry so much.

Almost looks like something like water/nute mix got on the leafs during lights on ......however it does look pretty dark green and that coupled with the yellow tips coming in ,,.is a tell tell of a lil bit heavy on the N .....you could probably back of on the N some if you havnt noticed that already ......GL

Just the trio schedule but I was thinking of amending that with some molasses for the soil micros

flowering plants need calcium/ mag. you can put some egg shells and Epsom salts in the blender with hot water blend on high and make it as small as you can.

I have a bad habit of not being to careful with the pouring but I broke down and got a watering can. I have had issues in the past with water bubble lenings before the can. My nitrogen has always been high but the only time she claws is from needing water she's been drinking like crazy with the temp spike thanks for the looking out.
