Im currently 1 week into flower. DWC 5 inch net pots, 400 watt metal halide hortilux blue, full canna line of aqua Nutes. PPM 850, PH 5.8. Had to spray with neem oil due to spider mites about 4 days ago. Just lollipopped the plants as well. Showing yellowing, with new growth stunted and curling. I think one plant may have a zinc def but im not sure. Please help!!!!




this is the second time im posting this and the plants are getting worse and worse, but for some reason I NEVER EVER EVER get a response to any of my posts... please help

does it look like a cal mag def? Im using "top notch" nutes according to the hydro store, shouldnt these contain cal/mag? My ppm of tap water is around 80ppm, which isnt on the hard side?

You think its a cal/mag def? My starting ppm is around 80 which isnt too hard? And im using canna nutes which are pretty high quality, shouldnt those contain cal/mag nutes as well? Thanks for the help

Lollipopping won't cause a nute deficiency.
Them girls are hungry.
When did you cut back on the Nitrogen or did you ?
Not familiar with your line of nutes, so what does the ingredient label say the quantity/percentage of Calcium and Magnesium is ?
What strain are growing and the recommended flower time ?
Sativa's and Sat dom's obviously bloom longer and therefore NEED Nitrogen longer.
I'm talking the first 3 - 4 weeks into bloom, especially for 10+ weekers.

raised ppm to 1050. Phed water down to 5.5 and added half a tsp of epsom salt. Lights off now, hopefully they will be ok. Any thoughts?

Keep PH between 5.5 and 6.0, with 5.8 being the "sweet" spot.
Below 5.5 and you lose Nitrogen uptake.
Above 6.0 and you lose Potassium uptake.
Give them a day or 2.

First, new growth aways looks lighter than mature growth. They do look a little hungry. Get your ppm up to 1000 at this point and keep increasing every week. I'm in 6th wk of flowering and I'm at 1600pp and will be at 1800ppm before I cut back and flush....The more nutes you push at them the faster and bigger yield you'll get...If you get a little burn on leaf edges, that's okay....if it gets bad, cut back your nutes a bit, but you should be okay...ymmv... I use Advanced Nutrients 3 part + B-52.

80 ppm? Never said that. I bumped up to 1300 yesterday. Im in my second week of flowering, and they should be a little farther along i think. Ill post up some pics in a second.
