slight yellow leaves any sugestions??

Its pH of the reservoir the slab is slightly higher ...... I will look into calmag asap. I fully change the water every week and i use ml to gal to get the nutes right and always ph balance after :thumbsup:

COOL.
Yup, get your CalMag running and that will turn around fast. I see no other problems with your system. Don't let your slab get much over 6.2. You're fine, and weekly res changes, while overkill IMVHO, aren't a bad thing at all!

Also what do you think of the nute schedule I am using??:420thought::420thought:

I'm not familiar with that one, but judge your nute schedule by the health of your garden! You rplants look good; you will want to BACK OFF just a hair on your strength until you are certain they can take the slight increase in overall ppms that the CalMag will give them.
Personally, I run by the EC numbers more than 'x mL of this and y mL of that', just making sure that the RATIOS of A to B (for a 2-part system) are consistent, and watch the plants for signs of burn or hunger. I start new clones aroun EC 0.8- 1.0 and work up over the course of the first 2 weeks of flower to the range of EC 1.6-1.8, then change the res after ~week 3 of flower, then go up to EC 1.4-1.6 with my BASE ferts and then add a bloom blaster like PK13/14 or GroTek Heavy Bloom up to about 1.8.

Go with what works for you. That system is working. Don't fret. :jointsmile:

One other question off topic. Do you think i can kick over the lights to 12/12 soon. Its been 36 days since the seeds came up not sure on the sex of the plants yet. I need to know asap i bought a magnifying glass but im not sure how to tell before flowering if their is a way.:pimp:



i will post a few pics of today

Go ahead and flip 'em because they are still going to stretch a lot! You'll have to look for pre-flowers; if they aren't fully sexually mature yet you may not see them and will have to wait a little longer.
You gotta get yourself a dirt mother going, man!!! SO much easier to grow from clones in hydro... OMG you will be so happy...

:thumbsup:

just took these

Yeah dude, your fert strength may be a TINY bit hot but you are flipping soon to flower and it's like, whatever; they'll be on a new schedule anyway with bloom ferts and then you start over haha!
Flip now or that room is going to be Jungle Stylee. I'd get a small circulating fan in that back corner ASAP before you get stagnant air issues.

I already took clones from each mother and labeled them to see witch plant i liked best to keep her for cloning purposes...

thank you for all your help:thumbsup::thumbsup::thumbsup:
