Hi thanx for the info guys the lights where at 80 cm from top then over time droped them to 60 then I upped them to 70 thinking I could be light burn for a few weeks still no improvement thus droped them back to 60 I'm sure it's not light related well I guess

Really not sure added cal mag even upped nitrogen but tops still yellow with some leaves ppms are 1160 over night droped abit to 1090 should I up them more not sure as I'm starting week 7 hoping to grow abit more till then end of this week then add some bloom and strat lowering the nitrogen todays pics @Waira on lights are 600 w leds
 
....not an N issue, N defc, always starts with lowers, as it's readily mobile within the plant; most of the micronutes, like Fe and Zn, S too though that's a secondary level nute... plants need significant amount of S!
.... not bleaching either, though borderline overly strong light can magnify this paleness when other key nutes are defc.,... dial nutes back some below 1000, and consider getting that Earth Juice Microblast, a great micro-supp' that's also going to put S in there, most of the metals are in sulfate forms in this product- :thumbsup:....
 
Yeah I think it might be an iron issue as for the light in lifted it to about 80 cm above the canopy if I find the problem how long will it take to see the leaves green back up again just to have an idea as for the earth juice I was planning to switch to General Hydroponics 3 part by Monday we thinking should I do a change over mid grow or try in finish up this lady with what I'm using the Hortix what you guys think ?
As I feel there is more ppl out there using it and could offer better advice on products they have used like general hydroponics
Basically IV had this yellow leave problem from day one I'm sure it might just be my lack of experience as it my first grow:deadhorse:
 
Different base nute's is not the fix here, though switching should be OK,... Foliar treatment with a micronute supp' is the fastest and best way to deal with it, help hold things over while you rework the nutes and double check pH to make sure it's not overly acidic (locks out S) or too alkaline (locks out Fe, Zn, et.al)....
....yeah, this girl has been troublesome all along,.. it happens, mate, I've had plants that grew OK but seemed to have some sort of uptake problem with micro's in particular,... It took some serious blasting with Optic Foliar Transport and EJM to load up enough to quell the symptoms,... Transport is a sort of special carrier solution that allows temporary penetration through the leaf surface (cuticle layer) allowing nutes to sink right in vs. trickling in via the stomata by the usual foliar spray methods....
 
Hi guys is there a real basic way to do the foliar spray don't want to spend much money on it at this point like can I use my micro in a spary bottle type of thing ?

Going to install a heater in Rez is I think the cold might be causing this issue as temps at nyt drop alot to below 15c in tent but I got a heater in Rez for my little seedlings and they doing great colour Wiz

You still need the dedicated micronute supp for best results, using the "Micro" part of a 2 or 3 part system may not have the full coverage of micro's, plus it's loaded with N... but look at the bottle label and see which part has Fe and Zn,...it can help! You'll need a wetting agent for sure, which helps it coat and stick more evenly instead of beading up... Coco-Wet is great, not expensive at all,... castile soap can do in a pinch, make sure it's not loaded with fragrance though; spray tops and bottoms of leaves, more stomata are located there vs. topside....
