Help do you know what is wrong with my plants?

Aloha,

Thanks for taking the time to possibly help me with my babies. I am a first time grower and I cant figure out what is wrong with my plants. PLEASE HELP!!

INFO: 400W, 20 on, 4 off. 6.5 PH, 3 fans air in and out. 3 Gallon soil pots, 5 weeks old grown from seeds, blueberry sativa. Mist every other day. Water every 3 days. TEMP 81 Humidity 65-70 Currently not adding any fertilizer or nutes.

Problem: About a week ago we started to see some yellowish spots on the leaves. They start at the bottom and work their way up. Two plants now have 4-5 leaves with spots. Please see attached pictures. After doing some research via the web we thought it may be a lack of Magniesum, Some of the other plants had leaves folding in. We sprayed with epsom salt water this seemed to help them. ??? We check leaves daily for bugs other problems but they look good. Why do I have yellow spots?? I have attached two pics hope this helps!!

Mahalo friends for your help!!

what type of soil? what type of water are you using?

container is too big also.


-shake

We are using tap water that we let sit out for 24hrs.

I dont think its the soil because the spots are only on two plants? If it was wouldn't all my plants have spots?

Fill this out and copy/paste it to this thread. Include as many pics as you can!

Anybody???

I have a strong idea on two or three issues you need to work on, but we usually don't offer guesswork when diagnosing plant problems.
As previously suggested, copy and paste the troubleshooting form here...fill it out as best you can, and we'll get right on it. The more information you can provide, the more accurate the diagnosis is likely to be.

Again, fill out the troubleshooting form. Much of the information you have been given I agree with......the pots are too large, the plants look over watered or under watered..... Thus the need for smaller pots at first....the water goes way down and the upper part stays dry then the roots reach into the wet and the plant gets sick, like I think we see here.

So, fill out the form and give as much information as you can, what you have given is not enough for good assessment, it is all guess on the part of all of us.
Thanks!:D

I GUESS MY BIGGEST QUESTION IS WHY THERE ARE ONLY SPOTS ON 2 PLANTS? ARE MY POTS REALLY TOO BIG? WOULD TRANSPLANTING THEM TO SMALLER CONTAINERS BE TOO MUCH OF A SHOCK FOR THEM? ESPECIALLY SINCE THE OTHER PLANTS ARE DOING FINE?

I have attached some more pictures of my grow room and a picture of my temp reader. It records temps for the past week and keeps track of my highs and lows. I have another 600W light that i am thinking of adding. So I would have both the 400W and the 600W light. Would this be too much? I started with more plants then probably needed because I figure halve of them will be male. I want your thoughts!!

Stop with the epsom salt. It's fine for correcting magnesium defeciencies, but you're killing 'em with an overdose. I'd flush well on your next watering day. Find and read the "Epsom salt isn't a miracle cure" thread...

It's tougher to downsize than it is to upsize. I'd leave 'em where they are.

What are you using for nutrients? They still need to be fed.

If humidity is that high, I'd avoid spraying them. Mold issues develop quickly, especially in a warm, humid enviornment.

You've got too many plants in a small space. As they grow, they're going to overwhelm that area. You're going to have to split them, half there and the other half in another area. They actually look pretty good. The pots are the right size but later you might want to put them into 5 buckets. Typically low nitrogen appears as yellowing of the lower leaves and works its way up. If it's been 5 weeks now and you haven't given any ferts, it's probably time to do so. Not too much though, just enough for now to see if it helps. You might consider only watering when the soil looks pretty dry on top. You could get a dissolvable fert that ideally has everything in it, like boron and sulphur, etc., and just put a few drops or granules in a quart of water and see if that helps. They do look a little pale green, which could be another indication that they need some nitrogen. If you want to spend a little more, I always recommend the DynaGro 7-9-5 fert to people. It has pretty much everything plants need. But you can use whatever you want. Just not too much of right now, eh? The DynaGro is just 1/4 to 1/2 tsp in a gallon for soil application.
