So this has been an interesting week... I finally bit the bullet and created another grow space for #1... kind of slapped it together in a hurry but it's functional and will serve the purpose which was to ensure she had enough room above her and around her to grow. She was really outpacing her sisters in terms of height (she's 26", the sisters are 18.5 and 17.5) so getting the light at the right distance was becoming more and more of a problem. I'm super happy with her new home and so is she!
Her sisters presented me with a different challenge - spotted some calcium deficiency going hard in one of them and starting in the second one... so both got flushed and put in 1/2 strength Big Bloom in the last gallon... I cut out all the Grow Big - not only was there a calcium deficiency, their other leaves were turning a terribly dark green indicating nitrogen toxicity which has caused the calcium problem since my pH is spot on... and I'm now searching for a new nute line as I'm really unhappy with how these ladies have NOT tolerated them. Fox Farm has always been a bit of a struggle with my other grows and I THOUGHT I had figured them out - but this grow is proving that I have not and I don't want to waste any more time or money on them. I doubt I will switch to new nutes with THIS grow, but my next grow will be fed something else.
All in all, though, a good week and the ladies are officially in flower! Exciting!!
