Looking for some help

Hey guys,

Looking for some advice on what to do with this thing. First off its grown in 70% FFOF with 30% MG perlite(I was in a rush and knowingly used this against my better judgment). It is currently 30 days Since I switched to 12/12, under a 200 WATT citizen COB setup. I didn't feed it during veg due to available nutes in soil and mg perlite. Once I flipped I started feeding it tiger bloom with a half dose of grow big here and there. Everything was good until roughly a week when the black dots started to show up towards the top of the main colas....currently my PH on the run off is 5.5, I am thinking it may be a calcium defieciency due to lower PH? I top dressed it with A couple tsp of dolomite lime 5 days ago and have also been mixing in a tsp of the dolomite lime ito the last two watering.

Any info, tips, comments are welcome!


Thanks

PS, in the bud shot does it appear that the plant has gone hermie on me ??

hermie traits will be seen on the bottom of the bud area, not the tops.

here is one cause of your issue "half dose of grow big here and there."

follow the directions for best results. feeding shouldnt be guesswork

Ok, anyone else have any other ideas?

Could be you went to heavy with the tiger bloom to soon. You need to ease into using tiger bloom until about the 3rd week of flowering.

Ok, last water which was yesterday I gave her straight ph'd water with a tsp of dolomite lime, hoping to bring up run off a bit but still right around 5.5-5.7, hopefully she gets back on track in order to finish somewhat strongly. I

Looks like Ca deficiency to me, rusty rash is a classic sign. The dolomite is pretty slow acting and needs bio-activity for it to be plant consumable. I would get something with calcium nitrate aka Cal/Mag+ and treat that soon or it will chew up your leaves. I struggle with Ca in my 4th week and it's exactly where you are, not sure if it is the COBs and/or the coco based soil but yeah.

thanks Buy, that's what I was kind of thinking as well. I'll hit it with a shot of cal mag next watering.

Thanks

Your welcome, I have been constantly frustrated with Ca issues. I am hoping switching to Jack's 321 nutrients will give me some relief, and so far it has.
