Browning of leaves,transplanted into new soil today

Ok so these plants have been through 3 motherfucking transplants now...this was the easiest one...below are some pics of the browning occuring on the larger of the two even though they have been treated the same and are the same strain....any ideas? they were originally in the same pot when they were young...then transplanted into seperated pots that were too small (fuck right?) also the soil i transplanted them into had a little nitrogen in it already (0.05) in the form of earthworm castings...also befor i even transplanted at all when they were in the same pot my buddy who gave em to me gave em miracle gro all purpose so maybe the spotting is a mixture of miracle grow and the soil having nitrogen? little over fert?...either way now i have transplanted them into 5 gal. buckets and into im proud to announce FoxFarm Ocean Forest soil....i havent fed them yet but i have NSR GreenLeaves Grow and Bloom also how often should i feed it once i do begin to use nutes?...i do not have a PH kit so im hoping in between the Fox Farm and the RO water ive got some of my bases covered at least.....also i saw NSR Green leaves Boost Juice today in the store should i buy it? worth the purchase? any advice or anything at all appreciated thanks!

nothing? bump

bump..............

not sure buddy , but mine are doing the same thing, im thinking something with the ph in the water, try buying dilluted water and using that once and see what happens

what ever you do when you add nutes start out a 1/4 of what the bottle says and work your way up to full. nutes 1 time a week

That browning sure looks like a modest light burn, althou I've never seen a cfl actually do that to a plant... might be from the tin foil, but I'm not sure.

If it's not light burn (althou it sure as hell looks like it) it may be mag def, in which case some cal-mag or molasses will solve everything...

thanks for the advice its not tin foil though its a cut up emergency blanket lol pretty reflective though but no issues before with it so im thinking its the fucking miracle grow my buddy gave em along with the soil with worm castings...just bad mix of circumstance along with the stress of transplanting
