Hey, first time grower here, my plants are 24 days in and yesterday I noticed some brown spots appearing on the larger fan leaves of two plants of the four I'm growing...woke up today and checked them and it's getting worse. I'm not sure what sort of deficiency it is so any help would be great...thanks

Cal-mag def, or are they covered by other leaves laying on top of them? What's your run off at? Ph and ppm or ec?

Hey, they are near the top of the canopy and are getting light, I'm using CMX which is basically like Cal-Mag. I'm growing in a peat/perlite mix, checked run off yesterday and it was 5.7. Have been watering with distilled water ph'd to 6.3
What nutes are you using and what dosage?also dosage your feeding cal/mag.
I'm at day 27 and was using Floranova Grow with CMX (Cal-Mag) at half recommended dosage from day 14 but noticed some slight yellow tips from nute burn on some new growth so stopped and haven't added floranova in last 12 days and have just used distilled water ph'd to 6.3 with 1/2 a mil per litre of CMX.
I'm in week 4 and plants are starting to pre flower, at my next watering in a couple of days I was planning on starting with the Floranova Bloom at 1/4 strength and working up to 1/2 strength.

...looks like P defc. kicking in,... start the bloom nutes ASAP, start at 1/2 strength.....
Thanks Waira...will be feeding them in the morning and see how they go. I'm sure they need a feed after nearly two weeks.
