If my maths is correct she’s drinking about 6 and a bit litres of water a day... lol I upped the nutes to 590 last time with more flower food should I stay at 590 this time then up the next time or shall I up her again?

Thirsty girl!

If you have fairly low RH I wouldn't go any higher. When drinking heavy they pull up extra nutes they store in the leaves which leads to toxic salts buildup and you don't want that. I tend to run heavy during the stretch then switch to feeding Lucas Formula style with 75 - 50% of the ppm I had during the stretch and making sure my K is now higher than the P and give them extra sulfur for better trich development.

:peace:

I see so just keep her at around 590 until week 3 or so then drop down to around 300-350 but with more flower food than anything? Thanks oldmeduser glad to have your brain to pick! Lol

350 seems pretty low. I'd be closer to 1000 then dropping to 500 - 750 for weeks 4-6 maybe then allowing it to drop naturally while I just top up with water and maybe some sulfur and some added K. I have separate stuff to do that with.

Maybe should stick to that level until the end of week 6 and she how she does.

What is your RH at?
