I'm not sure what's wrong with this one. It is 5 weeks old and just started 12/12 lighting. It has what looks like nute burn but also the tips are turning upwards. I flushed it 5 days ago but it's still spreading. I've only fertilized once 2 weeks ago with Fox Farms Big Grow at 1/2 strength. The 250 watt HPS is 1 ft above but the other plants don't seem affected by the heat. Also, it's in a cool tube with a 465cfm blower sucking air from it and a fan blowing on the light as well as above the plants. The temp inside the box hovers around 85 degrees. It's growing very slowly also, the other plants are also growing slowly but don't look sick like this one. Any ideas? I don't have a ph tester that's any good. Could it be that I haven't given them enough ferts? I got this from the troubleshooter.
3) a) Margins of the leaves are turned up, and the tips may be twisted. Leaves are yellowing (and may turn brown), but the veins remain somewhat green. >> Magnesium (Mg) deficiency. b) If not, go to #4.
4) a) Leaves are browning or yellowing. Yellow, brown, or necrotic (dead) patches, especially around the edges of the leaf, which may be curled. Plant may be too tall. >> Potassium (K) deficiency. b) If not, keep reading…
