They are all outside, and heat does not look like thislooks like they are gettin really hot... check the temps
okay, what does heat look like... smartassThey are all outside, and heat does not look like this
what pic? the first pic has not got nutes yet.Looks like nute burn
the first pic , no its only 3 weeks old . in foxfarm soilSo you haven't fed the pictured plants?
are you sure pic 1 is nute burn? i have not added any nutes yet, i leaning on a P def.Sorry I couldn't check this out sooner, had some internet problem.
1 and 3 are nute burn. 1 has dark green leaves -> N toxicity -> eventually nute burn. 3 is also a nute burn, but is also affected by cold.
2 and 4 may be P defs IF the plants are in flowering. If not, then it's also a nute burn. It's easy to figure out. If you flush, and more leaves start turning like this, it's the deficiency, if the problem stops, it's a nute burn.
the tips are brown , foxfarm soilThat's surely not P def. The edges should have shown some significant brown by now. Plus, the leaves look very dark green, a clear indication of too much N. Are you useing miracle grow soil or some sort of time release nutes?
