Wk 6 of flowering.. white widow strain tips starting to burn or turn yellow.. ph is at 5.5 going by the runoff water. Thought I may have given too much nutes last wk. so this wk I skipped a feed and just did back to back water no nutes to see how the plant would react. All help & advice is helpful

They are definitely looking nitrogen heavy, but not too far along to where you have to do anything other that back off on the EC a little. I don't grow in soil, so I'm not sure if you should skip a feeding or what.

Im week 6 into flower I haven’t given any nitrogen in like 3 wks maybe and the only nitrogen that was given was in the soil. I guess I’m worried if it will affect my plant because I’m so close to harvest.

Burnt tips and dark green leaves usually means N is creeping up. They have at least a month before they're ready. EC = electric conductivity. It's scale like PPM, but more universal. Just lighten up your nutrient mix. If you're growing in soil I assume the plant takes longer to show signs of deficiencies, toxicities and improvements. I wouldn't be worried, they look good. Just a little excessive nutrient regimen that can be cooled off a bit.
 
Those cant be week 6 of flower. Autoflower at 6 weeks maybe, the tops havent formed yet. Might want to check runoff. Im probably wrong and they are the size of my arm. Btw tips have barely a touch of burn.

You ain't anywhere near harvest. Worry about getting through flower first, the finish line is too far off. Wk 6 overall maybe? When is your next topdress due or are you feeding bottled nutes?
 
I will agree that they look younger than 6 weeks, but some strains are just slow. I see stacking going on, and I don't see anything that would suggest that they've been stunted.

It’s been 6 wks since I flipped the lights. The plant itself is 4 1/2 ft. I checked the run off it was a ph of 5.6

yeah it’s been 6 wks since I flipped the switch. It’s a white widow strain. I was reading that they can take up to 10 wks for it to be ready

wk 6 since I flipped the switch. Plants been growing since august is when I popped the seeds. It was getting all its nutes from soil. Started giving bottles nutes two wks after I flipped because I repotted two wks before I flipped and soil is only good for nutes for like 4 wks.
 
I know I’m few wks out of harvest. I read the last two wks I’m not supposed to feed any nutes or water? Anyone can help with info on that?
 
White Widow can run like 14-15weeks easy.
I just started another myself about 3 weeks ago but I top dress my soil after transplanting.
In soil you want your pH a little higher than the 5.5...this is a long flowering strain and you don't want to risk lockout. 6.3-6.5 going in but allow some room for drift.

Yeah well I was going off of what people were saying is the grow time for it then I started seeing the burn on the plant and held off on the nutes this feeding

I meant feeding as opposed to flushing. Definitely want to back the veg off a little and increase bloom now. I think your plan of a few waterings without food was the right call.
