Nanolux og 1000w hps and 400w hps have one plant directly under it and no problems at all they are og kush autoflowers been giving them nutrients since week 2 and decided to give them just water ph to 6.5-6.8 for a change was that a bad idea ?

 

[GNick55]

it wasn’t the cause, though keep feeding them.
so you have two lights at the same time? so 1400 watts?
am i correct?

 

[Kaleatwood18]

Yes 1400w temps are 76-80

 

[GNick55]

Yes 1400w temps are 76-80

how big is your grow space?
how long have the plants been under 1400 watts?

5x6x5 just introduced the 400w 4 days ago didn’t think my 1000w was enough coverage because I only have 5ft ceiling
