One part mix, Supernatural Bloom Aqua nutrient is specially buffered for flowering and fruit set in hydroponics systems.
Works well with Supernatural Superboost and Bud Blaster.
Bloom Aqua features the latest in high performance ingredients such as ammonia free calcium nitrate which is the purest form, and other select minerals that contain higher levels of oxygen.
Powder form - completely water soluable and stays dissolved without any residue.
. whats budblood (i mean content-wise...blood meal based???), and why are you using it now?
. whats the pH of the fertigation water? before using and of the runoff, plz...
....only cuz ya forgot to list this..
other than that...
whats your R.H.? ya may need to raise your humidity a bit..
....plants can not recover in too dry an environment...
too low an R.H. also accelerates nutrient lockout in plants...especially K
I have a feelin it's a micro nute burn.(?) I've never seen it on the edges only though? Usually it's sploches in the middle of the leaf... weird.Doesn't look like it's slowin em down much though.Anywhoo,good luck wit em.Take care...BC
Your in coco right?? ok... you need to "fluctuate" your ph... do this.. raise ur PH to 6.0 how often do u pure water?? I would do it every 3 to 4the watering... when u do.. PH ur water at 5.6 it will raise during the time its in the pot.. allowing ur micros to be uptaken and clearing ur medium a bit...
I have the same issue.. the important thing to know is... how to fix it... How much LK are u giving per gal?
I assume ur run to waste? do u ALWAYS let 10% drain out the bottom when u feed?? make sure to do this AT LEAST when u give pure water.. thats how I do it..
Are u using coco SPECIFIC nutes?? cause that makes a diff after time when it comes to K and CAL locking up in the coco..
Also do u let the coco get sorta dry? cause overwatering can cause problems with nute uptake etc.. causing things like this..
OVerall I'd say ur plants look really good... remember that boodblud is HIGH K and K locks up in coco... I quit using full dose in coco.. I use 1/3 dose now.. and often I don't even use it at all and instead work in PK around 3 wks
I've actually found it creates more problems than it solves by letting them dry out a little between feedings. The best results I've had with coco were from feeding 4x a day via drip for 15 minutes. Once coco dries out, it messes up the ability of the coco to provide nutes to the plants (especially K and Mag)...plus it's extremely hard to overwater in coco since it holds so much air.
I do think your nutes are a major contributor tho...you'll want either a coco specific nute or a soil/coco nute (like PBP). Since you've got more than enough K in the nute mix, it's an issue with the plant being able to uptake it...
Check out the coco forums and you'll learn alot more about coco's quirks...
Imo the damage looks pretty old like it was necrotic many days ago when there was a problem which it since has recovered. I agree with the others that it got overfed.
Verite: sir, i tend to agree with you because the clone still in my veg room shows the same tip burns...i think its a old problem because they seem to be doing fine
