Outdoor Grow Flowering week 3-4- Lower yellowing and purple/red colouration

Hello, so im in week 3/4 of flowering my outdoor plants. I use a 3-6-6 NPK fertalizer with ph balance included. Around a week ago I noticed the leaf's looked almost glossy, and self diagnosed this as too much nitrogen, so I flushed the plants and that issue seemed to go away. Now I am noticing not only red/purple stems (genetics) but a more than a couple fan leaves are turning light green/yellow and developing a purple tinge around the edges that seems to spread. I have looked on many different sick plant forums and not found an answer.

Also the weather just changed from the 3 month dry spout we have had to colder wet weather. I have heard cold nights can turn the leafs purple but the pictures I looked at were more, blotchy.

Thank you!

Looks like they need more P. Try some hydro flowering nutes you can use every watering. And get some saucers under the pots.

Thanks! So the 3-6-6 isnt enough? And yeah ill put some saucers to retain a bit more of the fertilizer before it just runs off.

It could be getting locked out due to the salt build up. Flush, re pot then start hydro nutes.

What medium are you using? What is your feed / water schedule? Are the plants always outside? Do they get rained on? Are your nutrients dry salts, liquid, slow release? What are the 'cold' temps you're dealing with in comparison to earlier in their life? Based on your pics, you look to be about 2-3 weeks into flowering. Consequently this is, on general, the most nutritional demanding period of their lives. Whatever you do, don't go knee jerking your reactions; your girls aren't that bad.
