Iron deficiency? how to correct?

So my first thought is that you may have a potassium deficiency, in the second picture, you can see some of the older leaves very dark in the center and yellowing from the outside of the leaf in. Nitrogen gives more of an even fade over the leaf and starts on newer growth first. Magnisium deficiencies can kinda look the same, though. Not sure if you got a lock out or deficiency, what’s the feed schedule, pot size, last flush, light size?

Sounds like you did all the right things, are your plants using all the water everyday? I guess they could being smaller pots and all. Be sure you let your coco dry out and get some oxygen to the roots. I feel like it may be more important, or at least anecdotally, that The dry phase is more important with VegaMatrix line. I didn’t seem to have the same issues with synthetics the last time. In flower you don’t want to let your girls droop, from lack of water, but the pots do really need to be much lighter than after watering. When in the perfect zone your leaves will be pointing up, reaching for the light.

Just reading back over your information again, I have been pHing down to 5.5-5.8 in my coco, to allow for that upward drift, my run-off comes out between 6.12-6.56. If you want to stay true veganic you can use apple cider vinegar. I’m not the only one here to do that. Be sure to check the new feed chart in the cannabis cultivation section, what I have been feeding my girls in veg. Pro-Tek 5 ml/gal (optional), Grow- 12 ml/gal, Bloom-7 ml/gal, Boost-7 ml/gal, Prime-10 ml/gal, Amp It- 2.0 ml/gal, plus OG Tea 7 ml/gal powder measured in a graduated shot glass. Mix it up, pH down to 5.5-5.8. That seemed to get my ladies in good health. I have one plant that is still a little on the yellow side, but otherwise growing healthy, it take a couple 2-3 days before you can see the color fade in.

I’m glad to see that my train of thought was on track with you and Kyle, Lightspeed.

Awesome sauce! I actually hit a couple of mine with to low of pH, you can see the last few pics in my thread, it really only did damage while the soil was freshly wet, but it did a number on my haze cross. I thought it was over feeding at first, then when I was looking at pH pics it all made sense. As soon as the coco/peat/perlite mix dried out some, they seemed to rebound. Will have new pics tomorrow the first day of 11/13.

I checked out your photos, I’m. to sure what these people are doing these days, way over thinking it, and trying to get to something. Get back to the basics. That’s system is very limited. Unless plants have time to sit in water and soak every day, they are getting a fraction of nutrients. Just because a plant grows in something or someway doesn’t make it good or right. Your need to put those plants in a normal pot and great as normal. No wonder I hardly ever see these drain to waste systems. And definitely  don’t trust runoff  readings from it. That kind of system also doesn’t need watering daily either from the looks of it. Oh man…..

1. any type of drain to waste or hydroponic growing is not real growing, thats common sense. the only people who argue are hydroponics growers.

2. do what you want but if your watering everyday i suggest using 1-1.25 ml per gal of amp it.

3. vegamatix is designed for drain to waste but doesn’t mean its recommended.

4. flood and drain can not do coco very well so no I’m not referring to that, sorry for typo.

5. as far as what i see. its a 2 gal net in a 5 gal bucket. if water to much daily the roots gets lockout casings multiple issues. if watered to little then the water will travel to same areas and paths re wetting same spots. this will cause the plants roots to stop searching which causes smaller roots causing smaller yields, this will also cause patches of high nutrients which can cause issues. causes few other issues as well. as far as perfect everyday watering, thats almost impossible since you would have to know precise amount of water, nutrient and oxygen plants need daily. you just need to use 2 gallon pots with a tray and water every few days. you be doing better to saturated the basket and water every few days or when it says its dry.

i started growing bout 16 years ago, luckily i got started before the market was saturated with crap knowledge on growing. most stuff nowadays is just thought of to sell magazines. go get a basic gardening book and follow it, everyone. when people get some really nice sweet delicious herb, its cause the people did the absolute basic. nothing like self teaching either though.

Coco has the oxygen holding properties, in a flood and drain type scenario, in which the res is oxygenated, and the pots are allowed to wick up the water, or in a drip system. When you treat coco like soil, and water to saturation and runoff, the oxygen comes in as the moisture is removed from the soil. If your plants are in  oversized pots, “clown shoes”, you aren’t going to want to water to run off, Driver has taught me in that case you want to water with a solo cup worth or basically what the plants will use in 2-3 days. If you were to fully water to runoff, you fill in all the space in the coco where the oxygen will be with water. It gets displaced. After I water, like to lean my plants to get drain off extra water in the coco to help get more air in. By removing the excess it is replaced by air.

The pot above is a 5 gal root maker pot, this lower pot is a #5 tall trade pot. I put 1/4″ holes in the sides spaced about 2.5″ apart to allow more air into the root zone. I get about 4-5 days between waterings.

real growing is planting in traditional pots. using soil or soils mix. if a plant completely dries out in one day, it needs to be watered more or you need to repot the plant cause its root bound. if your watering every day with little amounts of water the root system will not spread proper. as far as plant size and watering, i typically wait till three internodes and start feeding otherwise they get plain tap water. if having issues in veg just feed half amounts or feed every other water. coco can hold oxygen but that doesn’t mean to water daily.

if you think you have iron defiency put a nail in your reservoir or a nail in each pot of soil, this correct most with slow release. iron defiency is not common, this is probably associated with too wet or too dry of soil which either will cause issues.

the baskets in a bucket is not a bad idea actually, its how they are used. the issue with those it, when you have to raise out of bucket, the light hits the roots causing slower growth and less yield. one would want to fully saturate each bucket, let dry, then do again.
