I am four weeks in flower in cocoa under a kind 750led and 315 lec and an HLG eco 550 using GH organic I'm getting these purpleish stripes on my leaves on my wedding cake also I have a smoothies that showing some weird yellowing little splotches on the edges The leaves feel a little dry also I flushed a couple weeks ago my run off ppm was at 3000 I brought it back down and have kept my feed low under 1000 is this phosphorus deficiency possibly ?maybe lock out ?please help

Could be a one time wave of damage from the flush and or ph.

What are you feeding and ph / ec.

I agree 3000 is purdy scary high.

your media ph might be way off from that high EC. I'd check that, then start feeding with a much lower EC, with lots of runoff, with the PH adjusted to your ideal. 1,000 ppm is still high, I'd shoot for 700 and get the ph fixed.

Nice yes it is super high I couldn't believe it got that high I'm in fabric pots and for some reason I'm not getting any runoff but I did another flush got it down to about 1400 ppm my next water I'm gonna just start super low and get a bunch of runoff it sucks because I'm in the fourth week in flower thank you I'm using strength or less on a lot of my feed as well I'm using s synorganic Probably about 400 ppm of synthetic

I've got the purpleing on a couple of my plants, I just thought it was genetics combined with cool dark time temps.

I saw something really interesting about running LEDs and purple striping on leaves I guess it comes from a high PPFD possibly I could be off it might be something else but it's a YouTube video I'll try to find it and attach it

Would the magnesium deficiency be in mid flowering stage or could it be genetic to the strain?
