These have been in veg for 5 weeks and flower just under over 1 week, using coco on a drip system with 600 watt light. Read up on coco locking out mg so started adding epson salt, here are the pics, any other information is very very helpful. Ph of water is 6.2 6.3 and ec 1.2, lowered EC as they seemed to do better. done hydro before but not soil medium coco.
Used coco bricks only
Used canna A and B coco
Basically been slow growth since start, all are about 1 to 2 feet, from smallest to largest, Put them in flower on the 15th with 48 hr darkness. Noticed stunted growth before that so flushed with tap water which shown improvement, after trying to dose with nutes at 1st because leaves looked yellow like they didnt have enough nukes, then realized it was the opposit, so flushed them for 5 days, gave them a half dose of what it said (light feeding after flush) and tried epson salt as I read coco can lock out mg. more or less the whole story, still not happy very worried.

I never grew in coco but dont' you ph it to hydro's say 5.8 or so
Do you give it a good little flush each watering or feeding
If not you could have a salt build up
Its defiantly some type of lock out
