Have some plant issues

My plants have been vegging for over a month and close to 2 months now, I am noticing all my plants are starting to have yellow tips and also 1 of the plants is looking not as happy as the others and also dosent have as much growth as the other 2. I have been feeding them water for alittle bit but i have started to feed them botanicare pbp nutes once at 25% strength and the second time at 50%. I am not sure what is going on but im thinking its either calicum or nute burn, they are all in 7 gal smartpots with ffof soil. Here are some pics of the one plant, I can take some more because the one leaf has gotten worse. I plan on just feeding them water for the next 2 times and then adding nutes. So if I could get some opinions on what is going on or how to cure I would greatly appreciate it.

nitrogen and sulfur deficiency maybe........ocean forest batches can be random as far as strength......try adding 1/4 teaspoon of epsom salts per gallon of water. maybe even 1/2 teaspoon if thats not strong enough, read more on salts before adding. miracle gro makes some good nutes that are water soluble and really high in nitrogen, 24-8-16. best of luck man!

It looks like lack of nitrogen to me but maybe a little cal/mag def. There's a whole section with pictures for this also.

My guess is slight light bleaching. Anyway I've had it, looks just like that.

I've had that as well, was hoping to find out what it was.

I dont know if its light bleaching , it could be , but I just think its something else because that plant is the least healthy looking , I will post some more recent pics on here later this afternoon.

I'm not saying there can't be a nute problem that also looks like that. But I've OD'ed em on lights a bit and that is the result.

I think the damage happens when the leaflets are starting to unfold from themselves, like the size of the tip of your little finger when they are really tender. Also leaves on a rapidly growing plant have leaves pop out and partially expand overnight in the dark. Then Bam the lights come on. Burns the most tender tissue a little, and then they go ahead and expand with the damage.

If you have another problem making the plant weak and unhealthy looking it will be more susceptible to other problems, like insects, disease, and environmental stresses including light.

On the other hand, maybe it's puny because it's light stressed, maybe just a sensitive phenotype.

Good luck

Thank you everyone who has posted on this thread. I am just alittle frazzeld because I have never had a plant problem before this grow so I am behind the curve.

You'll be back, and we will be here to help you out.

Heat/light stress. Move your lights further away and increase ventilation.
