Hi guys, I'm thinking I have a phosphorous deficiency here, but would very much appreciate any feedback (it's a long trip to the nearest hydro store...). As you can see in the pictures, I have a lot of small purple-ish dots/blotches on a few leaves, the stems are purple, and the plant is quite droopy (though she perks up after a water/feed, she begins to droop again within 12-18hours). These 'spots' appeared approx 24hours ago, though the drooping started 3 or 4 days ago. Indoor, coco/perlite (70/30) grow (11ltr/2.5gal pot). Feed consists of H&G A&B and some epsom salts. EC going in equals run-off EC. Water is (hard) tapwater with high calcium levels. Water/feed once per day. Under a 250w red spec cfl, with some additional lighting from a 125w blue spec cfl. High humidity, temps around 18-25'c (65-80'f). She's a Lowryder#2 approx 42days since germ began, and has been flowering for just a few days. Cheers for any input.
