Slow Growth and Purple Leaves

My sprouts are almost a month and a half old and barely 2 in tall. The lower leaves are purplish brown color but otherwise healthy looking.

600w MH lighting 18/6
79-80F with light on. Around 70F light off.

Any ideas why growth has come to a standstill?

If u can post pics it will help. Are u giving it any nutes? Is it in soil? What kind? Do u know the soil ph. Ur temps are a tiny bit high but nothing horrible. What's the ph of ur soil and wtaer? How about runoff? Sorry but u will be asked all these and then some before u get the answer ya need.

Sorry it took me so long. It's been almost 2 weeks and i've still been monitoring them. They're completely stagnant. Unchanged at all. The soil pH has been constantly 7.0 and i water every 3-5 days depending on when they need it. I check the soil and wait until completely dry to water. I did try a very very small amount of Foxfarm Grow Big to see if it would help (1/2 teaspoon per gallon) and they actually responded worse. I have read that purple leaves generally mean too cold at dark hours.. could this be the problem?

Here are some pics taken yesterday and they are about a month and a half old now :-|

They don't look very happy in the soil. More often than not when plants just cease to perform they don't like there meduim, especially if you've tried to feed them and they do not eat. What soil are you using and does it have any npk values to it? If you bring your ph down to 6.5 that may help them as well. A simple transplant to new soil will often take care of these frozen in time plants.

It was called Pro-Mix Organic. The guy at the hydro grow store recommended it to start seedlings in. I was trying to find the npk values on the bag but don't see them..

throw them in bigger pots with better soil. and lower the ph just a tad. they should be way bigger if they are a 1 1/ 2 months old. mine are only 2 /2 weeks old and the smallest is 10 inches. good luck man hope it starts doing better

Is it too soon to move them to bigger pots with Foxfarm Ocean Forest Mix? Or do you recommend something else with the same smaller pots?
It's not really about the size of the container yet but not a bad suggestion since you will be changing soil anyways. You will eventually need a larger pot so now is as good a time as any. Right now though it is about the health and growth of your plants.

Fox Farm Ocean Forest soil is a great suggestion for soil however since it is mass produced it can be inconsistant. I use FFOF but I mix it with coco. I use a 60/40 mix of coco/ffof this mix is very plant friendly and the roots love it which means the plants love it as well.

If you do end up going with the coco ffof mix try finding the dry compacted block of fine coco fibre. To use it put it in a large tub and treat with cal/mag water ph'ed at 6.0 before mixing with the soil. It will take several gallons of water and each gallon will need at least a teaspoon of cal/mag. The coco will absorb all the water real quick. :peace:

So I replanted them in FFOF yesterday. I kind of messed up the root system on the first one a little bit but then got the hang of transplanting the smaller plants and the rest came out perfect. I hope that first one will be ok as well though. How long should I expect it to take to get some noticeable results? At this time I cannot notice any change at all.

Give them a few more days to catch on then they will take right off. Good choice on the soil btw. As long as there were some roots left on the first plant then it will be fine. A plant really only needs one root left to make full recovery after a semi botched transplant. I accidently broke the entire root ball off a plant once, ooops, and the darn thing acted like a clone and took off about a week and a half later, I was shocked, but I was not about to let that plant go to waste. It was a fully vegged plant getting ready for the flower room, had to veg it for a couple weeks longer but she ended up being the bigger one out of 4.

Good luck and you should see results soon:peace:

Thanks for all your help. One last question: Any suggestion on a good soil to start seedlings in?

i had that with 3 of my plants its either weak genetics or lack of root growth and purpling is sometimes due to cold weather. go buy some thrive alive and then feed it and do some foliar feeding and you should get some type of growth and your plant should atleast be almost 2 feet tall if it was veging for that long and move the light away some and see if it stretches and what kind of soil are you using?

FFOF is one of your best bets. Black Gold is also good. I use FFOF but always mix it with something light and airy to delute the FFOF just incase it is too strong for my seedlings. I have cut it with seedling starter soil and with coco, I prefer coco as a mixer becasue it is neutral, light, and airy. For the seedlings I mix at 70/30 coco/ffof and once I transplant the mix goes to about 60/40 or 50/50.

I think your ph was too high. It was probably actually higher than 7.0. The first element to get locked out at high Ph is Phosphorus. P def will stunt growth and turn leaves yellow to purple.
If I started seeds today they would probably be bigger than yours by the time yours come back around IF they come back at all. You might wanna start over is what I'm saying. Best of luck either way.

Do you have any updated pics?
Here are some I just took.









Noticeable difference.... the leaves are greener and there are new fan leaves shooting out of the top, but I'm sure you've already noticed that on some of them the leaves are curling in. Is this shock from the transplant or a problem with nute burn from the new soil?
