Hey guys!
Could use some help. Not sure whats going on with my girls. It started 2ish weeks ago. Noticed the lower leaves were falling off very easy. Turning yellow. The new stretched growth at the bottom is dying is so dying at the tips. I can never tell the difference between deficiencies. I tried to flush them out last week and no real change. I'll include pictures and stats. Any ideas?

Plant in front is Black Jack and 2 Royal Highness in the back.

2 600w LED full spec
Coco
Ph in always raised to 6.0
Water daily with run off
PPM in 600
PPM out about 600 also. Usually have it lower than going in.
Nutrients are measured per gallon, GH Flora series
Cal mag 3/4 tsp
Micro 1/2 tsp
Grow 2ml
Bloom 3 1/2ml

I raised bloom up a tad after flushing. Thought it needed more K. Tops look good but after seeing these pictures I took I realized the bottom is not good!

thats a pretty thick canopy maybe no light is getting to those leaves so the plant is dropping them. many people lollipop, meaning remove all that under canopy growth so the plant can focus energy on the top colas.

your tops look good. it could also possibly be a nitrogen or magnesium deficiency both present themselves as yellowing leaves from the bottom of the plant but it honestly doesnt look like that to me. if anything sounds off with your grow it could be that pH is a bit low.

Those plants have been in flower for what, about three to four weeks? How long did they veg?

When numerous deficiencies appear simultaneously like that during, or right after the flower stretch period, I immediately suspect possible root bound situation. Have a look at that before piling on more nutrients. Your pH is good apparently, so I doubt it's pH related.

Note though that 600 PPM seems somewhat low at that stage of growth, so if I'm wrong about being root bound, it may just be not enough nutrients.

I was also thinking that. These plants I swear protested showing their sex. After 8 weeks I forced them in flower. Trimmed almost everything off but they still exploded! Lol

If the tops look healthy I wouldn't do anything big with nutrients. Its lack of light

am I safe to cut those branches? Or should I just let them alone, die themselves.

Thank you guys so much. I'm stressing the F out. Thought cutting during flower was a no no. There is so much that popped out once in flower. I couldn't believe it. Thank you again!!

You mentioned you water daily. Is that out of necessity or just a habit? The plants do look like they drink a lot, but regardless, let them dry out a bit between waterings.. maybe every other day...I water based strictly on weight of the pot..let them get light before watering.. Also agree with the others to trim all that shit off..good luck man

Not true! It doesn’t just give up on leaves this early into flowering. Yes last 2-3 weeks but not now.

I had the same issue and corrected it with a higher feed. I too was feeding around 650 mark on an Auto but she needed around 800. Luckily I KEEP those leaves so if a deficiency shows up it’s not on leaves doing most of the photosynthesis!!

This is 5th week flower.

I would bump the feed up and go from there.
