I added a p150 to my p300 and it seems like its to much light and is making the leaves turn yellow. It's in a 3x3 tent and the lights are 28" from the shortest plant and 24" from the tallest. I've been adding 1tsp. of calmag to nutes every watering. Anyone had this problem? Is it the lights or something else? @FullDuplex @PlatinumLEDTom @archie gemmill

I've seen it a few times and currently have 2 seedlings that showed it after adding in bloom switch. I'm well over 30 in above, they typically recover and be careful with the cal mag. Calcium toxicity will lock out nitrogen.

Also I run 2 p300 in my area so I know it's kicking out light. It's common I think with the intensity. I also have a bunch that are not doing that. So I think it depends on the strain or plant.

Yellowing on the top..they are 67 days old but a couple are lagging behind. I'm hoping they will be done in a couple weeks or less...lol I guess I need to start flushing sometime soon anyway. @FullDuplex @archie gemmillall leaves turning yellow,or from bottom up ?

Dude that late in flower under Platinum lights is completely normal. Or at least from my experience it is. So my theory on it is that they are the closest to the light so those the laves transpiration rate is way higher than lower fans. I usually finish with yellow on top or black:smoking: but thats another story.
Hold on ill grab some pics of that late stage in flower. Your fine and any tweaks now wont net you anything. Yield is done....
