Yellowing of leaves, curling and brown tips

Since my last post have run into heat and light issues.

The temperatures was around the 90's but all that is now under control. The temp is now around the high 70's and have added in another 125W Envirolite.

The humidity its fluctuating a lot from the low 30's up to high 50's.

The plants have been growing really well but recently are starting not to look ill. On the plants the leaves are starting to turn yellow, (on one the some of the leaves are brown), some of the tips are turning brown and also curling.

I started noticing this happening last week and it has seemed to be getting worse.

could this be a nitrogen deficienc?

Looks like is could be a MG deficiency. I had the same problem due to PH lockout. crush up some epsom salt really fine, then put a few spoon's into a spray bottle. spray once a day or so...

what types of shops can you buy those salts from

any retail store really ( Wal-Mart, Target, even grocery stores im pretty sure )

They aren't getting nitrogen and the tips are burning from the outside so there is some kind lockout. You need to flush like crazy and when they start getting healthy again resume a feeding schedule.

Epson salt will catch it if it is mg but there's about 20 other options on this one.

Thanks for all the feedback

I have given all the plants some epsom salts.

how long should it be until i can start to see some results?

bumpity bump

can anyone help me out??? my babies were looking pretty healthy until all of a sudden i started to notice brownish red spots that start from the veins and progress outward.. the leaves then turn yellow and curl at the tips.... i read could be due to nutes or possibly spider mites... does anybody have an idea???

need more info cmurda sounds like nutes to me though. I would flush and inspect for mites.

Bongfish how is it looking now any change?

i had this same problem. flush and flush good
