Hi everyone. This is my first grow and my first post. I have a five week old Auto AK. Growing under a Galaxyhydro 300w LED (actual wattage around 140) and two 23watt CFLs. I've been using a mixture of Foxfarm Ocean Forest and Foxfarm Light Warrior, mixed about 60/40 but not exact. Up until a few days ago have only given PH corrected water and an Epsom salt foliar spray.
Lower leaves have been yellowing and a few have died and fallen off with some brown spots. I've been using an Epsom salt foliar spray on the tops and bottoms of the leaves but the problem has persisted and is spreading. My concern now is that I've misdiagnosed the issue and that the plant will die if I don't get it taken care of.
A few days ago, before I fed any nutrients I also noticed yellowing at the tips of the new leaves at the top of the plant. Just the very tips and as those leaves have grown the yellow tips have remained but the remainder the affected leaves look good to me with no spreading. I would have assumed nutrient burn but again, this started before feeding. In case this is a light burn issue, which I don't really think, I've lowered the plant from my LED first from 18 to 21 inches and again to 24 inches.
Two days ago I fed Foxfarm Big Bloom - 3 tsp per gallon and some molasses - either a 1/2 tsp or 1 tsp - should have written that down. Also included 1/2 tsp of Epsom salt per gallon - I've avoided feeding Epsom salt to the soil but I was desperate as the yellowing has persisted. Also, two days ago gave a foliar feeding that included Epsom salt, molasses and a tiny big of Foxfarm Tiger Bloom. I won't be feeding any Tiger Bloom to the soil until I'm into flowering. Again, all described and photographed problems started before any feeding I did Friday. Since Friday, I've noticed less drooping of the top leaves. As of late last night, the yellowing and spotting was continuing to worsen, though it appears to not be any worse today than last night. Hoping something is helping.
About a week ago I tested my runoff water and found the PH had gotten too low. I corrected that and since then have transplanted to a larger pot and new soil.
As I understand, in the case of magnesium deficiency, spraying with Epsom salt is a quick treatment but in the two weeks I've been doing this symptoms have only worsened. I initially did the Epsom spray out of concern of a sulfur defiency - the leaves were all light green. After only a day or two of spraying the leaves darkened a little, but then the yellowing and spotting started.
Since the the Epsom salt spray has not stopped this issue, I'm worried the issue is something else, or that the spray is causing problems.
Any help in diagnosing or suggestions to treat this and get things back on track is appreciated.
