No worries at all buddy. If I'm totally honest, I think its an iron deficiency. ( Do a google image search and you'll see that it's what I said). Iron deficiency, also called iron chlorosis or lime chlorosis, starts with a yellowing of the leaves in between the dark green veins, giving the leaves a spidery look. Over time, the leaves become whitish and start to die back, eventually resulting in stunting and dying back of the entire plant. 31-32 is a bit hot. I'd say to not go above 28 Degrees, especially in flower or you'll get fox tailing which is another issue caused by too much heat. If you can turn it down to 400w (If dimmable) that would help a lot, or if you cant raise up the 600w to around 55-60cm away and do the hand check at the top of your plants.. if its too hot for your hand after 10-15 seconds, then its too hot. Do this till you get a not to hot but not too cold distance.. that is the sweet spot. I would say 5.9 is more for a hydro set up.. soil pH can be anywhere from 6-7 pH.. with 6.5 being close to perfect for soil as its what mine is at. I hear what you're saying buddy, but 9ml is a lot, is that every feed? -Or every other feed? as I'd say you should feed as follows.. Water, water then third feed, nutrients. Its just once you've burned them, unless you quickly act on it, it gets worse thats why I say to flush. But instead of adding all those nutrients, you could of just added what was needed until the deficiencies show, which can then be corrected if that makes sense. When I say flush that is with plain water, yes.. But of the correct pH (6.5) Check what your normal water pH is. The only nutrient line I know that you don't need to correct the pH is Advanced nutrients. Not sure about bio bizz, and at 7.2, I've never given my plants anything that high. Yes, so if your pot was 10 litres.. you'd flush through 30 Litres of water. But as you are so far into flower, just do twice.. and you'll see how much run off is nutrients and the salt build up, get it as clear as you can then start over. If you check my grow, i flush while entering flower to get rid of the excess Nitrogen and after boost up the P K.. with very little N.. I completely cut out the nitrogen by week 3 of flower. Check my (Stardawg and Girl scout cookies grow) All the advice I give you is what I use myself. So I hope it can be of help, proof is in the pudding ;) If it helped let me know. Hoping you sort this out buddy! Sorry for the rushed reply, anything I didn't cover just let me know! Goodluck
