Leaf Curl

[reddy1]

This sick girl is 18 days into bloom in a mix of coco coir and worm castings. Water is R.O. and nutes are sunleaves guanos and cal-mag plus. It was unseasonably hot here the past few weeks. The room temps were in the mid 80s f. Now they're about mid 70s. Humidity is kept around 45%. I'm not totally convinced that it's heat related because the other's aren't showing the curl problems. I did recently have a hermie plant(now gone) that curled up, not down like this one. Any ideas?

First can you get a picture without the hps on so I can see what the color of the plant is? It looks from the picture that is over fed.... but can't be sure yet

Need more information.... how often are you feeding and how much?
what is your ph? Did you wash your coco real good before using it?

can't get a better picture right at the moment.

yeah it's been overfed N for sure(evergreen leaves). that was probably the amount of worm castings, peruvian sea bird guano and cal-mag. feeding light(1tbl guano(24 hour nylon soak), 1/4 tsp. cal mag, tbl molases) every watering, every 2-3 days or when needed. i've been using the indonesian guano for higher P the last few waterings. should i flush? i water to 20-30% runoff. i use botanicare coco and it's been good to me with the amount i wash it. i have no clue as to my pH. yeah, i'm new at this.

Good lord that is to much; you should only need to feed weekly most of the time as long as you water before 7 days then if you have to wait that long then you would have to feed every watering... but the amount you are using has burned them horrible. Yes most defiantly flush them gals out with LOTS of water..... how big i the pots?

You use like 2x the amount of water say you have 2 gallon size pots then you would use 4 gallons to flush.

Also she does not need this much nitrogen in flowering; you have caused her to stunt her bloom... to much nitrogen causes delayed flowering.

I would only use the P guano and the cal mag for now....

You ph you need to test the run off that comes out your medium/soil. You water and catch the drainage and you can use ph test strips from pool stores or get a digital ph pen which will cost around 100 bucks for a good one. Self calibrating ones are more money. If you are tight on a budget then ph test strips is your best bet... do not get a soil tester those things are nothing more then an expensive hole poker to help get seeds in mediums.

So you would want to water her and then take that water run off after it starts to come out and put the test strip in it...... I would wait a min or 2 when enough runs out of the bottom to get an accurate reading though.

pots are 5 gallon bags. so 10 gallon flush? wow that's a shit ton of water. cold tap water with clorine(7.8 pH) might screw things up. i get my RO from culligan. don't have a machine yet.



i think i'm just going to continue to lightly feed them, no more N except for what's in the cal-mag. i'll update with any changes noted.

I have flushed my plants with tap water last 2 weeks of flower it's not going to screw things up...... you have a huge mess right now man. Use tap water to flush her out. Then you can switch back to RO if you want.
I would only feed them weekly after flushing and stay with 1 tsp per gallon of each bloom cal mag.
