Aprox 5 weeks old. 600 watt hps in a 4x4x7 grow tent, pushing plenty of air, using pro-mix as a medium and using the entire GH floranova nutrient line. Ph is steady 6.0-6.3. I asked a local hydroponics shop owner(stoner) and he said i was underfeeding. Alls i know is im using 1.5 teaspoons of flora veg and 1 teaspoon of the bloom per gallon along with smaller quantities of the other flora product line. Any insight would be nice ive had this problem since day 13
 
If you could take some pics under normal light so we can see the real colors, that would help, but my first couple questions would be........
Are you still vegging?
That one tip looks burned, but I can't really see what the discoloration looks like.
I can't believe 5 weeks and that's all you've got.
Have you checked to see if you're root bound?
I think that may be part of the problem, but at 5 weeks old, you SHOULD be able to start ramping up to full recommended dosage for your nutes..
Just for a comparison, here's what mine usually look like coming out of a Solo cup around 20-25 days.
This pic was taken at 21 days from sprout.View attachment 2915129
 
My apologies these are old and new photos. They went from cups to 1 gallon to now 5 gallon buckets. Definitely not root lock, and better pics will be on the way as soon as I leave work, it was hard to judge how they looked on my phone.
 
I am going with over fed. Why are you giving them bloom nutes while they are vegging?? Your soil should carry them for awhile without adding nutes. I am learning this exact thing right now!!

Take some better pictures without those lights on so everyone can see the colors.
 
Looking at your HPS pics, the one factor I would rule out is underfeeding, in all likelihood you are overfeeding.
Better pics would help...good luuck

NO!!! Keep doing what you are doing. If you switch up you will be learning all over again. Keep notes on what you are doing and the results and over time you will see the light!

And always remember that it is VERY easy to over feed your girls..............
 
I'm about to start transitioning to flowering. The general hydroponics for floranova says to use both for roughly a week. Also promix is ph neutral. It contains absolutely nothing for the plant to feed off of. Better pics coming in 5 hours
 
looks like your pushing the fertilizer to hard back of there to small to handle it that strong. use 1/4 until for a wile. after there a foot tall bump them it back up.
 
Well I'm going try something a little different, I always allow the medium to almost fully dry, but I have been going everyother watering with a feeding. I think I'm going to go every two now, water, water, feed. And cut the amount of nutes going in by about half. Thanks for everyones opinion, I really just wanted another set of eyes to tell me what they thought. New better pics coming in 3 hours
 
white widdow 001.jpgwhite widdow 003.jpgwhite widdow 002.jpg this is the browning patches, that leads to the eventual curling, crisping, and dieing of leaves. is this actually over feeding?
