Whats wrong with my plants?

[nitrous oxide]

I planted these four plants in one bucket(stupid i know) with miracle grow organic choice potting mix. Almost all the tips of all the leaves are turning a bright yellowish then brown color. Also another plant has blotches on some of the leaves.

are u feedin nutes yet?

I fed them with only like a quart of diluted 12-8-4 miracle grow plant food like 2 weeks ago. Plus the soil it was in came with nutrients already in it.

whats the temp and ph at

 

[nitrous oxide]

I would guess that the temperature is around 75 to 80 but im not sure. As for the pH i dont know exactly because I only have some cheap strips, but it looks like the ph is around 7 to 7.5. Nitrogen levels are at b

 

[yuri orlov]

keep it at 6.5

 

[candylime12]

flush those plants with some water at a ph of 5.0 that should bring your ph down.
i wouldnt feed the plant nothing but water for a while if the soil has nutes in it

It's the soil man, NUTE BURN from the slow release in the MG organic soil. Transplant into better soil without slow release. i.e. fox farm ocean forest...
