Slight plant problem.PLEASE HELP!

MY FIRST GROW.(inside my closet)im using a 150w HPS light,plus 8 CFL (6 blue and 2 red).I have air circulation(fans) my humidity is 50% border of dry and normal(i knw its dry in ther) could b one of my problems.SOOO my leaves feel dry and crispy.The new fan leaves are droopy and thin plus dryness( look at pic) I believe i have CAL MAG def.I JUST GOT CALMAG and added superthrive plus my nutes(jacks classics) in a full Gal.umm this should help them out.(started this batch of nutes,superthrive,CALMAG, TODAY)

those pics are what my plants look like,ther not doin tooooo well.Ther growing still,but the TOP half of my PINEAPPLE THAI(bigger plant) is droopy and dry.(only top half) SOOO im thinking maybe the lower branches are sucking up all the nutes and shit.Like maybe the top isnt gettin fully fed?????

THANKS for listening and im looking forward in getting help.

droopiness is sometimes from overwatering. how often is that? https://www.rollitup.org/marijuana-plant-problems/150004-plant-moisture-stress-symptoms-solutions.html

whats your feeding schedule. How much are you giving them of each? going by the label? or what?

what stage of life cycle you in? veg?

Jack's Classic I think has the 16 nutrients that MJ needs. I've never used it.

need some better pics honestly, hard to tell.

i AGAIN agree with buraka, all the superthrive in the world wont help if youre not giving the plant time for the soil to dry, the roots need to spread and find moisture, thats part of the process involved in making a good root base esential for vitality, leave the next watering until the pots are real light (just not so dry that the soils pulling away from the pot sides) maintain this whilst carefuly monitoring for changes and hopefully youll see good start to happen.

plus just adding superthrive to something, or "the-next-product-told/pushed/recommended" to you may not help either. I've been there bro. Throw anything I can find to fix the issue, without understanding the issue.

how big are the containers? how often are you watering/feeding?

like Fallguy said, the "lift-pot-up"/weight method isn't a bad one. I for one religiously used to follow the water, feed, off, water,feed off.. when i was in soil. I think that is possibly not completely the wisest thing to do. It shouldn't be SET in stone. read the plants. feed the soil/roots, not the plants.

thanx guys for the help.So yea i water them once i see tht the soil is dry and i put my finger in it(i do see the soil coming off the sides of the pots)Soo which is like every other day or two.kinda depends.

Ther in vegi state.Im doin full strength right now. 1/4tspn and 1/8tspn of nutes,1/4tspn of superthrive,and 1 tspn of CAlMag.IN A FULL GAL.
i only fed them like 2 cups at first of HALF strength but now they should handle this FULL strength.(fed them only 3 cups each) still have more to feed them in the gal.
