Cannabis Troubleshooting

Ever since I started 12/12 my bottom leaves started to die whats happing? And what do I do to fix it?

[at tachment=13990:attachment]Hello all. First time post long time reader.I have a bit of a problem as you can see by the pics. Im using a 600w hps growing NL and Big Bud. Some of the leaves turn pale green in between the veins so to speak and eventually go brown and die. I add dolomite lime for magnesium and calicum.any comments greatly appreciated thanks.

Is this Nute burn?, they're getting worse everyday. I don't know what to do

well heres my problem i loaned a light to a buddy he lives in a house that is well a party house with 5 other people i loaned him a 250 watt hps light well every time one of his roommates throws a temper tantrum he cuts down a fucking plant they now have 2 1/2 plants they had 4 large females he just ripped the top of of 1 nw heres the real problem they started flowering a week ago and i think they will be going inside whey were done hydro i dont have the equipment to get a hydro set up going indebt i know save the money i would spend on bud but its 4/20 thats my excuse for today but yeah can i put them outside even thought they have been preflowered i live in the indiana…

I have a run2waste system with a 200ltre barrel. I use: - Advanced Nutrients (recomended ph of 5.6) - au60 root repair - fulvic acid - silica majik - nutriboost - advanced nute big bud (powder) I set the PH at 5.6. But when i check back couple of days later it's up to 6.2 -6.3 Whats with that? The Advanced nutes website recommends using nitric acid to bring PH down as the stuff most ppl are using reacts with some of the nutes. I might try it out as i'm putting quite a lot in to a 200ltr barrel, and I'am interested if anyone has experience in this

Hey there. I have 6 plants in coco fibre using GT nutes. Two of the plants are blueberry and the tips of the leaves are pointing downwards. It's only recently that they've been doing that. Maybe a week or so. Can anyone help?

If the leafs are curling up at there ends, does this mean too many nutes?. Or lack of water. I dleiberatly havn't watered them for 3 days to stimulate root growth etc. Making sure there's a dry period in between.

Hi peole ! This concerns my outdoor grow Here - thai satvia some leaf shots 1) top side 2) bottom side Whole plant shot . ......................It's easy to see it lacking Nitrgen What I am after is a means of dilivering a quick hit of Nitrogen ? Your suggestions would be welcome. The plants are entering week 4 of 15 (guess) flower. I have not watered/feed for a week. were in for 2 days of sunshine before a week of shitty weather again. I know at this stage of the grow cycle the plant switches from N to needing more P & K. I have a recomended nute called "…

Hi, I germinated some seeds, potted them in some coco, then about 5days later the stem on the babies choked, shriveled up. Died. This is something i noticed a while ago when my cuttings died the same way. It seemed pythium+root rot was the cause. So this time i pulled it apart and didnt see much wrong with the roots, although a bit yellow. No sign of rot. So i tested the ppm/EC of the coir it was 1.5-1.6 EC diluted!!! with 100mls of pure water so potencially a good 1.9 - 2.0 EC @ root level. Damn i forgot to flush the coco coir clear before using it. Because Im a bit rusty,what is the shrivelling up of the stem is due to? Could it be something else as well?
