I agree. OP stated "only the middle down." Said all. Be nice and helpful.
Very good examples of all three deficiencies in those pictures lol usually its hard to diagnose
Actually easy. Just need to hear the plants. They honestly are screaming to us if we could only see.
Wish folks learned a coco soil mix before going inert. LOL.So much difference of opinions with coco. Most of the stuff I've read from excellent coco growers is multiple waterings every day and some of the best are drain to waste systems with many feeds per day.
I run peat based ProMix HP and do soak well then allow the pots to dry right out before soaking again but have started watering a bit sooner and the plants seem to like that better. Feeding lower amounts more often also seems to keep them happier than the water-feed-water-feed thing. Using 3-part AN or REMO nutes for that. Lucas style after the stretch.
Coco always seemed like a lot more hassle, costs twice as much and not available locally where ProMix products are everywhere here during the season then gone until spring.
Definitely looks like you need a good feeding of the full monty. Lucas formula is better after the stretch to get the N-P-K- ratio swung over more to the P-K side and keep N levels a little lower so it doesn't retard flower growth. Still needs some N but lots less than veg or stretch. Needs lots in stretch but lots of the others too.
Doesn't look fatal!
I've done a lot of good DWC grows and you can't get much more inert than RO water.
`Apologies to the OP. We ran astray. But I grow very similar. Only really dumbed down. My years require ease of use. Soil /coco and 3 dry amendments and frass. Too easy. But just what I do.I've done a lot of good DWC grows and you can't get much more inert than RO water.
I experimented mixing HP with soil for a dozen plants or so and it didn't work all that well. Now I'm adding some manures and EWC with bio-char, lobster/crab meal and a good dose of a product called DynoMyco that's supposed to be compatable with hydro nutes. Made in Israel specifically for cannabis. Some Insect Frass too. Using less of the 3-part or get burn pretty easy but just getting into it so with a bit of practise . . . Seems to help with terpenes and big phat trichomes so more medicine I hope. I add some Carbo to feed the myco too. Either unsulphured blackstrap molasses or pure dextrose I got with some Mega Crop nutes I won here a couple years back. Have unpasteurized local honey that should work as well.
Got to experiment to make it more fun after so many years.
Lucas is FN Bloom plus Micro. Are you adding the Micro bottle too?
Overwatering used to by my main issue. Lol. But yeah...you want to let the soil dry out a bit between waterings. Not all the way tho. It’ll take a minute, but you’ll find the sweet spot eventually.
I’m starting to be able to figure out any issues on my current grow. My first grow...I was a lost puppy. Lol
You have no idea what you're talking about.
Thanks this is what I’ve always heard too!
You know what I haven’t calibrated my pen in a couple weeks or so, I didn’t think I needed to do it often so I’ll start with that! I also did buffer my coco before planting.
you need to water everyday to keep the ph inside the coco in check
You sure about that?..

Absolutely definitely sure!!!!You sure about that?..
Hydroponics using Lucas Formula
Some don’t get it, others do… Regardless we are here to help you better understand the Lucas Formula. The Lucas Formula derives from a man named Lucas who participated in online forums for growers who use hydroponics/soil-less growing. His nutrient feeding regime quickly became widely recognised...
