Hi all , on my first grow and not sure what to think of these girls anymore.
Growing 4 shortstuff seeds auto pink grapefruit now on day 42 in plant magic soil. Temps around 26 to 28 degrees c rh about 60%. Tap water ph at 7 soil seemed to be at 6.5 but not sure if I'm testing correctly!?
All seemed well through veg up until about week3 when starting to flower and brown spots and yellowing started to appear. I hadn't given any nutrients until day 24 as all looked healthy. I started on a daily dose of root regen at 1ml/l and day 28 started plant magic bloom at 1ml/l feeding for 2 days and plain water every 3rd. Day 33 I went up to 2ml/l of bloom and added 0.5g of Epsom salts to 7l of water and dropped the root regen. Day 35 added 1 feed of plant magic PK boost at 0.5ml/l to the mix.
Problems didnt seem to be improving spotting and yellowing was spreading up the plants and now tips and leaves were browning so I suspected over feeding and from day 36 have just used plain water. Now not sure if theres multiple defencies or if it is nutrient burn . Any help would be much appreciated buds really starting to look nice now and doesn't seem to be affecting them apart from stunting possibly hopefully I can nurse them through to harvest. Pictures below are what they look like now.

Starved out mate, from early on,.. Plant can store many nutrients, need to in fact for those in the wild,... if she's fed just enough to do OK, then demand really jumps (like during transition and bloom) and there are no reserves, and the feeds are low (1ml is not enough), she has to cannibalize her leaves to try and keep going... You have multiple defc., not burn from over feeding... N, P defc.'s stand out most, but it's masking others I'm sure.... feed her more, you might even run a blend of grow-bloom to get a little more N going in, there's still plenty of mass to produce and she needs N for that.... Feeeeed! 
up the dosage to about 4ml for a round or two, but watch her carefully,.. ease up dosage from there if needed,...
