What's your PH? i was having the same problems with the Hesi during veg, i was giving them 3ml per L and most of my plants were on the yellow side as soon as i bumped up to 5ml per L on flower they started to become green i think the problem was that when i was putting the 3ml per in it wasn't lowering the PH enough therefore causing lockout i may be wrong but thats the only thing that i could think of after all the Hesi feeds must work as their all cup winners.
