Hi everyone, ive been putting off posting thinking i could deal with my sick girls by myself but i cant let them suffer anymore.
Im currently growing a Brainstorm, two Big Bangs and two dwarfs. The problem is with the Brainstorm and one of the Big Bangs. The Brainstorm is 7 weeks old and has been in flower for 3 weeks. The problem is that up until i changed the lights to 12/12 it was a healthy strong plant, then it started to show some stress. It started yellowing between the veins. i thought this might have been Nitro deficiency as it was stretching when i switched it into flower. I fed it with half dose of Baby Bio as well as 1/4 dosing with flowering feed and very small dose of epsom salts. This didnt seem to do anything as it steadily got worse. I didnt feed it anything for the next week thinking i might have overfed it. On the smaller leaves the tips started to become more and more yellow with small rust spots on them, I have fed it agian two days ago with full dose of baby bio thinking it might still be nitrogen and Mg defficiency. I have also started getting big brown spots on the edges of some of the leaves. The Big Bang is only 3 weeks old as i wanted to try it as a 12/12 from seed. The leaves are yellowing and curving length ways almost making a tube. i Have only fed it a half dose of Baby Bio since it sprouted.
The ph on both are around 6.7 and i ph rainwater with the feed to 6.8.
The average temp of the room is around 78F.
The soil is Westland container compost with added potash(wish i read on here first)
the light is 400hps
both plants have constant fan blowing lightly on them
The flower feed is hammerhead 0-9-18 which was in the soil section on the site i brought it from but turns out its for hydros.
would really apreciate any help you guys can give me.
