Hi i am feeding at 480 ppm 170 of that ppm is my tap water. Nutes are frora 3 part series and calmag and my ph is at 6.0 going in and runoff ph is around 6.0 to 6.1. Plants are super cropped. Leaves are kinda dark and some are clawed. What am i doing wrong im thinking i shouldnt be adding calmag since my tap water is already at 160 ppm20200717_140453.jpg20200717_140445.jpg

You shouldn't need calmag with tap water.......I never have to use it.
Your pots look small......what size are they?
Also, your leaves look like you've been spraying them?

How many times a day are you feeding? In those size pots.......multiple feeds per day is needed.
You might consider transplanting.

I also have never needed calmag with my tap water with EC .4 and ppm around 190. I agree some larger pots might help. I think that 3 gallon pots are the sweet spot for a good size coco plant in a tent. I grow 4x in my 3 x 3 tent in 3 gal cloth pots in coco.
You might actually be under feeding, leaves look a little pale and growth is a little stretchy. By the time my plants are that size I am feeding them about 1.7 EC/850ish PPM and they respond very well with vigorous growth.

When you transplant I strongly recommend using cloth pots. I am sure that your plants have been root bound for a while now, it's even possible that's causing or at least contributing to the problem.

You mentioned the PPM and PH of your nutrient solution but only the PH of your runoff. How much runoff per watering (10-20% is good) and what is the PPM of your runoff?

Ph going in is 6.0 and 20 % run off with ph of 6.0

We know the PH, but what is the PPM of the runoff?

Also I really would consider using only 3 gal pots. You can grow a plant in coco as big as it needs to be in a tent in 3 gal pots. All the five gal will do is take up more space and take more nutrients to water properly. Also going from 1 to 5 gal is a big transplant. By the time the roots have properly filled the pots the plants are likely going to be too big to flower in the tent.

For soil in a tent 5 gal in great, but for coco 3 is ideal imo. I made this same mistake when I switched from soil to coco, and now I always flower my indoor coco in 3 gallon cloth pots.

Runoff ppm stays same as what i put in sometimes over by 10 or 20 ppm i already bought the 5 gallon rhizo bags so im a stick too it cant afford to buy more atm

I don't know what a rhizo bag is, but a 3 gal cloth pot should cost like $3-4 a piece. Do what you will, but I think you will find it more problematic (plant will get to big) and more expensive (you will have to use more nutrients) in the long run if you transplant them from 1 to 5 gal pots.

You will either have to cut them back more than is healthy, or they will just end up too big.

Good luck to you either way!

i have 2 ladies in 5 gal airpots in a 3x3,always wondered what is a good size pot for coco, ill be looking at trying out the 3 gal method.the plants usually uses abt half a gallon to get 20% runoff.

Be careful buying 3 gallon pots off Amazon. 80% of them are just lies. They are actually 2.5 to 2.75 gallon from tip to bottom. I learned that the hard way. I prefer 5 gallon and leave a few inches from the rim and its a honest 3 plus gallon volume.

Hand feed? I am new to growing indoors but have been growing since 1986. I start them on advanced nutrients grow micro and bloom with general hydroponics cal mag. After 2 weeks i switch to jacks 321 hydroponic fertilizer. its only needed every 7-10 days. You can buy it off etsy in 4-6 pound bags because the regular size bags are insane expensive. If you want to feed less often. Research Jacks Hydroponic 321vand follow the directions to the letter

Jacks is 5-12-26 part A npk and part B is 5-0-0, thats why you need to follow the directions so closely. its extremely hot fertilizer. mix 1tsp of A. disolve it completely (very important) then tsp of the Epsom salt, dissolve completely, then tsp of 5-0-0 and dissolve completely. per 1 gallon. Ive found that i only need to feed every 7-12 days. And it covers everything you need for a successful grow

They look good. By the photos it looks like you just watered which would make the leaves droop.

I haven't seen too many people on here with plants that look similar to mine. Yours are the first. Keep it up and you'll pull off my avatar.

I use tap water and still use cal mag fyi
