Im growing critical mass indoors under a 600 watt mars cree 128. I’m mid way through week 5 of flower I started seeing burnt tips thinking nutrient burn I flushed the soil with water ph’d to 6.2 for 5 days. Now I’m seeing leaves like this. Is my plant telling me it needs nutrients again if so what is deficient? Any help would be huge!
That looks like a calcium deficiency but Purple lights make it difficult to tell... Turn the LEDs off for just a minute,and shoot a couple with the flash,or any white light.
ok thanks I appreciate it. I’ll just follow instructions on dosage. Will it for sure kill my plant if untreated? How long do I have to treat it. Can I use dolemite lime until I get cal mag?
You need to treat soon, so make a 'tea' with dolomite lime,and try to dissolve some of it for now...then pour it all on and water it in.
