idk, they look like they need some cal / mag imvho. i just got this image from searching cal / mag deficiency in cannabis, and it looks like what you've got going on..
Thanks a lot for the info bro I gave them straight water and they already grew like an inch and are looking good!
Just lower the feed and if need be, get a nute with just nitrogen so you could lay off all that p&k. Excessive P&k will lock out cal and mag and , extremly excessive p&k will lock the whole plant rendering it unable to drink/eat much.
Thats strange, i fed my outdoor 16-16-16 all year and they didnt lock anything out. Can you explain this so i can understand what your talking about?
I've never had a problem with 10 10 10 but he may be correct tho
Hes not correct. P and K will not lock the plant out. Salt buildup in the rootzone reaching toxic levels will, but thats not p and ks fault. Thats an accumulation of total salts fault, not a two outta three macros particularly. Besides, nitrogen is usually the problem in most over fertilization issues.
your feed is fine. I like to cut down nitrogen at the end personally for better tasting bud but i run soiless too. Most experienced kids round here will tell you to cut way down on the calcium and nitrogen fertilizer the last two weeks.
Well thats because you fed them correctly. These ones are a different story. They are a bit burned and showing signs of low pH which is technically borderline lock-out. Its not that you cant use 10-10-10 ratio's i feel its easier to use something like 10-5-7 for a less experienced grower.
Meh, he says his ph is always seven out of the tap, which is on the high side. But most feed buffers the ph to closer to a 6.5 naturally. For him to see problems with low ph hed have to drop like three ph points just by adding feed to an eight inch high plant, so like quarter to half strenght or around 400 ppms. That doesnt sound like its possible either, so what are you really saying here? Are you just making this stuff up randomly? It's wonderful to try and help but you need to be on point with help or a guy will end up just chasing his tail and ruining a plant from bad advice.
Actually im wrong, i missed the part about pH 7 run-off mybad. He said his plant has all of a sudden slowed down on drinking water though and this would point to the medium/root zone.
....or low ambient temperatures, low air flow, and high relative humidity, with a little added overwatering to leach fertilizer from the substrate, no?
Yup that's also possible if the OP hasn't been paying attention to see if his environment changed. Hopefully he didnt overlook it.
