Leaf tips turning brown

5 weeks into flowering.400 Hps fertilized 2 times. Any help would be a great help I'm fairly new at this.Fox Farm and Miracle grow potting soil for the soil.

Did you really need two threads for the same fucking question?

we need a little more info.........fox farm nutes? which ones grow big, big bloom?? Also what type of plants you growing? what size pots? and what is your nute schedule?? also temps and how often do you water??

Mine are in 5th-6th week. Tips browning / yellowing on all plants. I dont have a ph meter. ^^ i use alot of nutes and distilled water + ph down. Uhm, they are beasts in DWC.. . I dont mind. as long as the burning/browning doesnt go past tips..

its going to keep going and get worse and worse unless you do something. you need to keep your ph in the right level.here is a very nice very affordable one, works great and they have very cheap shipping which is pretty quick(normally 3-4 days after order). Get a few extra packs of the ph buffer.

how strong was the dose of nutes? cannabis is pretty sensitive the first feedings and miracle grows time release nutes really dont help at all.

my ph is 6.0 I'm in soil and I just flushed all the plants. Sorry for the double post, it was an accident , no point in being rude. I have been fighting some heat issue , 67 at night and 88 in the day, is the heat the possible issue?
