amlez Posted March 11, 2015 Report Share Posted March 11, 2015 Growing in potting mix/composted cow manure/perlite 430ml potOutdoors sun in VERY tropical heat (pot wrapped in cardboard ‘blanket’ during the day for some insulation)27 days into flower (cloned mid October – had a setback when younger but bounced back well) This girl had been going gang busters (well at my level anyways!!) until only the weekend when she started to rapidly show signs of leaf yellowing lower down – didn’t worry too much until a few days ago when suddenly the whole plant is yellowing fast, and leafs are limp, droopy & lifeless.I did have an issue with the top of one cola developing what I presumed to be ‘bud rot’ mid last week, but I chopped that off and appear to have contained it to just that area (marked RED in pics)FWIW – pH pretty stable during grow in the high 6’s – fell to low 6 late Feb which I put down to feeds with Miracle Grow Maxfeed Flower & Bloom and some Rose Fertiliser (RichGro I think?). Got it back up to high 6 again with plain rainwater watering.I’d planned to let her run another 5/6 weeks – she’s nowhere near ready to chop, but I’m starting to panic as she appears to be sliding downhill fast. This appears similar to the issue I had with her mother in late October last year - she was a VERY healthy looking plant just about ready to throw into flower when out of the blue fell over & died within a week - very quick deterioration. When I pulled the stem/roots it appeared that the root ball had 'stewed' - ever since then I've been trying to shield the pots from the sun. (Last pick is the rest of the clan - all still in veg - that sit right alongside the sick one - and some in smaller pots that I would thick would get even hotter? - They're all going well??) First pic is the most recent I've got till this morning - taken just before commencing flowering early FEB. Last pic is the rest of the gang - all looking OK and under exactly the same conditions. Any advise/ideas welcome (I'd particularly like to hear from anyone else growing in extreme tropics where we get smashed by heat/humidity this time of year and if they encounter anything similar??)
