Plant Porblems, Brown Spots On Leafs, Dying And Yellow Leafs PICS INCLUDED

Thanks for the responces and help!

Well i think it was over nutes and salt buildup.

I tried to feed them with full strenght on the bottel which made things LOTS worse. Then I wattered only and then gave them some nitrogen and sprayed them with AVID.

After that didnt do the trick I flushed with clearex and lots of ro water. 2 days later and im back in the game! much better...hopfully it lasts. there is still lots of salt buildup on the top layer of the soil. Should i take it out with my hands or just leave it? I thought it was just from the rockwool before...

i just put the plants in 12/12 today.

Nuts I have to use

Super Bud Blaster 1-52-31
Flora Nova BLoom 4-8-7
Floaralicious 1-1-1
Licquid Carb Loader
Diamond Nector 0-1-1

How and which nutes should I use and when should I start? I dont want to over do it on my feedings.

I have almost 100 plants in the one room with 8 1000w lights. My plants are really crowded.

I have 1 more room with 5 1000w lights in it. I was going to start a new veg cycle so when these are done flowering I can start the new ones in flowering.

What do you think is better. Space the plants in 2 rooms so they have more room or push all these plants in 1 room and start the new room with vegging?

Also should I lower my lights? Or do you think they are at a good height?

This is my first grow. Thanks for the advice!

bump!!!!!!!!

as for the lights height i would definatly lower them if the temp in the room is controled 18"- 24" from the top of the plant for flowering. and with the rest you could get a sick system going.where you crop almost every 50 days give or take a couple.have the smaller room used only for mothers and clones a pre-stage room.you could save the money your spending on clones. nice fuckin set up it must put some bread on te table.
