@Brad2981 welcome to the community I can’t said nothing in reg. Coco but so far some of you leaf look like little nuts burns but @Covertgrower@Hellraiser@BobbyDigital they get you covert
I’d check your PPM out. FF products are known for creating salt buildup. It’s a big problem in soil, but I’m not sure about coco. It looks like a touch of nitrogen burn (some darker leaves and burned tips.) It’s not a big problem, but I’d get it under control before it becomes a problem if PPM is high.
You should be using Big Bloom and Tiger Bloom too. Tiger bloom is for flowering and Big Bloom feeds the micronutrients (copper, zinc, boron,…) that the plant needs. You should also be adding cal/mag at this point in the grow.
Yes at this moment I am using cal mag and tiger bloom, initially I thought was salt buildup and flushed with ph’d water best I could but since I have them in the netting I can’t get them out to really flush and drain as I would like
A lot of growers dose half of the FF recommendation and they do fine. You will still get salt buildup, so be sure to monitor your runoff PPM. If your runoff PPM and your runoff pH become hard to manage, it will be due to a salt buildup.
Ok so what’s best way to flush and check ppm runoff I have heard conflicting ideas on the internet , some say a little water wait then more water some say run 2x the pot size of water through ect…
Yes. Give a light feeding immediately after you are done flushing. Distilled is best, but tap water pHed is fine too.
I’d do 5 or 6 gallons for a 5-gallon pot. It’s best to use a flushing agent such is Sledgehammer (10ml/gallon) in the very first gallon only.
You might consider moving to Jack’s 321 nutes when you use up your FF stuff. Jack’s is easier to use and less expensive. I switched to Jack’s for my last grow and was very happy with it.
