Indoor Northern Lights Blue Auto - Nute Q

[cyberfox75]

Hi all, I'm growing 2 NL Blue Autos and they are now in their 7th week of growth. I'm growing indoors in 5L soil containers in a Grow Life tent. For the first 4 weeks I used 400W MH, then switched to 400W HPS. I'm feeding with Old Timer Grow and Bloom nutes. Seeds were bought from Freedom Seeds in case that's important.

I've noticed that one of the plants always takes about double the amount of nutes or water when I'm feeding/watering them. So my question isn't really urgent, and nothing's about to die, I'd just like to know why one plant is taking double the amount of food/water compared to the other one. Both plants are roughly the same height, similar amount of bud sites, and both are in the same soil/perlite mix and the same sized pot.

I've done a bit of searching around but can't seem to find an explanation for this. I'm hoping one of you autoflower geniuses will know the answer as this is really bugging me now!

I'm not sure dude??? I'm gonna take a guess one has a bigger root system so can drink faster????

I guess that's possible, but if the plants are the same height, same bud density, and in the same sized pots then surely the roots would be of a similar size and they should be taking in a similar amount of water/nutes. I've grown before and never seen this happen before with the same strains in the same growing conditions. Weird eh.

Anyway it's not bugging me too much as both are very healthy and a decent amount of harvest is coming my way very soon

I'm growing the same strain and was wondering if I'm having signs of too much nitrogen (the claw look and twisting of new growth) how could the bottom leaves start yellowing? I do t know if its cal/mag or is it being locked out by too much nitrogen? Should I just flush everything and see what happens?

Send some pictures if you can.We need to know your ph going in and runoff. That claw look and curly leaves usually means to many nutes.I would flush her for now and hold back on nutes for awhile and see if that helps.

My ph is between 6.5 and 6.8 and the run off is the same...I don't have a digital ph reader so I know the paper test isn't as accurate..when the lights are out they look like a healthy green. The one that looks darker then the rest is about 4 days behind the rest...they are 26 days today

Looks like too much N to me, I had a similar issue with my girls at roughly the same age as yours are now - it seems that these autos just don't like as many nutes as photo strains. All I done to correct this was to flush with rainwater at 3 times the amount of the 5L pot, so 15 litres of water for each plant. I then let it drain off and then didn't feed or water until the soil was almost bone dry again. Within a week my plants were back to normal again.

Hope this helps...

I flushed them this morning...hopefully I get the same results you did...I will keep you posted
