Trying to get someone to identify my problem: yellow edges

[Frogtownusa]

I have been reusing my soil and although I amend it the same way every time I’m having this problem with the edges of the leaves turning yellow.

Potassium deficiency maybe...

Plant Abuse Chart

Heat Stress : Look closely below, and you'll see the brown leaf edges that are indicative of heat stress. This damage looks alot like nutrient burn, except it occurs only at the tops of the plants closest to the lamps. There's only one cure for this...get the heat away from the plants, either...

Temperature in the tent is always between 75 and 80 Temperature in the tent is always between 75 and 80 Most of the time around 78° .... Mars Hydro 2000 is 24 inches away. Same as it is with every other grow. Never had a problem. :/

I’ve posted pictures for the last two weeks and haven’t even gotten an answer from anybody other than there’s a deficiency. Need to get a good soil test kit or something. Would be nice to know everything that’s in there without dragging this stuff down to the extension service

Did you click on the plant abuse chart? Scroll down & there's a pic of a leaf that looks just like yours (where I got it)

I like it but I’m just not seeing anything that looks like the problem that I have. Have been hunting for several days. The top leaves show signs of zinc deficiency when they’re first coming out. Very defined looking then they start turning yellow around the edges. Sort of like a magnesium deficiency but not exactly. I’m growing in soil and I don’t want to but I may have to flush the soil and just add bottled nutrients for the rest of the grow. Wish I could just add something but I think it’s got nutrient lockout for some reason which is kind of weird seeing that it’s a super soil unless that can happen

Give it a solid flush, the nutrients I use, when I see that, I just up the nutes and bam, fixed lol

 

[Hrenklin]

But if you fear a lock out give it a flush. And a small watering with added nutes
