need some advice

[cluezz]

hi guys, just beginning to develop this problem in the last 48 hours. These babies are in a bubbler system about 2 weeks now and they have been growing wonderfully.

I had some problems early on during the transition into the bubbler system. I had stopped top watering the grow plugs which i figured caused some burning on the younger plants in the system, I switched to pure RO water in the res and proceeded to flush all of the grow plugs for the next couple of days. They stablized and then i gave them a compliment of AN seaweed extract, F1 and H2 for a total of 300 ppms. The babies responded to the nutes tremendously in the next couple of days and put on a few inches of explosive growth. I then added some mother earth tea grow to bring the total ppms up to 400. as of this point I was very weary of burning these guys so i didnt add in any base nutes.

Overall all of the plants have been doing well, but since 48 hours ago, they have been curing upwards. and just 24 hours ago, they stared showing signs on the leaves. I have since then added the base nutes into the system and we are at a system total of 650 ppms at 6.5 PH There is a total of 5 gallons of water in the system. the room temp ranges between 80-85 degrees but it is cooling down here where i live. I have a 1000 w hps about 4 feet above the canopy top.

I cant seem to paste the pics in my gallery, but the pics are in there

check that the temp of your rez water is between 68 and 72 ideally and up to maybe 75*F at the top end.
check to make sure your pH is between 5.2 and 6.5, otherwise you'll have a range of lockout issues.
what node are your plants at? it doens't seem like you're overfeeding them, but if they're growing fairly quick they probably will need you to start introducing your nutes more to them
i don't know much about the nutes you're using, but it seems you've been using additives instead of starting out with a nice nutrient base

quick question guys, how come i cant post photos into the post? it says that i have urls in the post when i click on the gallery to post the pics, just wondering...

also...

should i then just up the base nute (im using the AN sensi grow 2 part) or go with more concentrated product like cal/mg

btw there are 3 different plants in the pics, lol i wish i could sort them for ya but havent figured out how to post directly here yet.,..

plant 1 img 6463 and 6465 (note developing problem on leaf tip on 6465)

plant 2 image 6458 image 6459 weird burn spots on the leaves (what is that?)

plant 3 6460 6466 6448 (probs listed in post)


thanks for all the help

cal/mg because ur using RO water with basically nothing in it, so use some cal/mag and you will be golden =]

i dont know about pics, i think it has somthing to do with over all post number...it has to get to like 50 or somthing

You can also use epsom salt also...
I use the Lucas Formula and people always say they use epsom salt for Mag when they use RO water....but i just use TAP water and ive never had mag. or cal problems ever...just a thougt

oh ya, it really just looks like a Mag def...get some epsom salt and you should be good man, or some cal/mag...ur choice, and this site has been good reference for me for any problems ive had before... www.ganjaguerrilla.net

You have to have so many post's to upload pics and send pm's... I think it's 50 posts before you can upload pics to the thread itself.

Hi guys, picked up some epsom salt, was wondering how much to put, what is the best way to apply, and any other critical info that might be needed

 

[MynameStitch]

For now I would use 1/2 tsp per gallon of water since the plants are not very big. When they get bigger up it to 1 tsp per gallon.
