What is going on here

[biggerbud420]

Couple of problems first soil is from my yard . ppm going in 17 ppm coming out 478 ppm that's after flushing it with a half gallon of water . Water pH 6.5 . It's been about a week and a half maybe 2 weeks since a gave them any fertilizer and then the ppm reading was around 300 4 days ago I did water them with some molasses water 1 tablespoon to a gallon of water and I did not use the whole gallon of water . Now I don't understand the burnt tips how can it be nute burn

i live off grid so i have no air conditioner and it has been near 100 degrees where i live also i think there might be white mildew could i use a hydrogen peroxide solution on them to kill it ?

there is 2 fans in there one blowing air out one blowing it in so could the tips be from being too hot ? i have 2 cfls and 3 led bulds in there about 50 watts total they dont seem to put out any heat at all

burnt tips is nute burn, in your case i’m guessing at over watering or not allowing the medium to dry out before watering again.
i don’t think that’s wpm.

Did you end up using hydrogen peroxide? just curious how it worked out.....that's what I did, along with clipping the leaves that were really close to buds that had any white on them. I came VERY close to harvest with this stuff.....it can spread so fast here in our climate in Michigan. Hope it worked out !
