My plants have been in flower for about 4 weeks now and have stopped showing any sign of growth for the last 2 weeks. I am feeding them Yates Tomato food, and they look green and healthy, just no growth..... Also there may have been a hermie in there, so the plants may have been pollinated, I dont know. Would this stop growth? I will post some picks sortly. Any ideas?

Can anyone tell me anything about the colour changes these clones are experiencing? I read somewhere that yellowing lower leaves is a sign of healthy rooting going on? The attached pic shows the yellowing (no sign of roots yet - they're about 8-9 days old) but there are also some other colours .. back left the newer leaves look like they have a purple/dark? colour happening also - just wondering if this is a sign of something i dont know about? :scratchin

Hey guys, two out of three of my girls are developing new growth with only single bladed leaves. They are about 30cm high and about to be re-poted from 2.5L pots into 20L pots. All the older growth is fully developed and looks fine, it's just the new stuff over the past few days. Humidity is around 60%, temp is 26 light on and 20 light off ( 1 x 600 MH) Nutes @ 18 (Canna coco). Cupboard is totally light proof. Any ideas fella's???

In between the last nute changeover and today, the roots have just about locked the lids on my tubs - they've grown down from the nets above and wrapped themsleves totally around all the tubing which is attached to the bottom of the tub - this has effectively locked the lid on the tub - I can just get my arm under the lid and to the bottom of the tub - but there's no moving the roots at all .. they're completely enmeshed with one another - any suggestions ? ya can't prune roots can you? I have another 5-6 weeks to go and either I solve the prob or I may have to stop as soon as the sprayers inside are jammed past unjamming. I can flush the tub without taking the lid off,…

I have a strange thing going on, I cant think of what to do or how it happens. But Twice I had put rooted clones that were in rockwool in to soil, Both times the plants have stopped growing and are kind going bonzai. This time it has done it with a seedling??? I raised the seed in a cube and then transplanted to my others seedlings. Is rockwool not compatible with soil or whats the deal?? I have always used rockwool with clayballs or perlite without it doing this??
