OK, here are some pics of some very unhealthy looking plants. The new growth started after I corrected the PH levels and was looking promising, but overnight some of the very new growth went brown at the tips. I've raised the lights slightly incase that's the problem and turned the fans up a bit, or does this look like nute burn even though my tests reveal very little excess nites? Or could it be a genetic thing, or just a stress thing from all the changes that have been made over the last couple of weeks? Should I just get some decent seeds and try again, this time with all the right specs? PH is 6.6
It doesn't look good. Unfortunatly the plants are dying my friend. They may recover and if so they will outgrow new seeds. They look to have sufferred from either one or several of these factors. Overwatering, over ferting, ph imbalance or improper ph correction, root rot. They don't appear to be growing. There is little nitrogen uptake. Mold is growing on dead leaves. Did they suffer heat stress too? Don't be discouraged. I am not sure the cause but many things can kill your plants. My experience was similar until repeated efforts taught me my errors. Hopefully we can figure out what happened. BOG
Hey Bushy, good to have you back Since the initial post I have flushed the hell out of my pots, and with a degree of success. I actually ferted the soil as seedlings stupidly, so I think nute burn was one of the serious issues. There is shit loads of new growth on some plants, and the even more unhealthy plants are actually showing new growth too (although I'm not too hopeful about those ones). The new growth is a really healthy green, and it's rapid too Fingers crossed things will continue to improve. With the necrotic leaves, if I leave them on the plants will the necrosis/mold spread? Do I need to prune? I ask this because I tried clipping a brown tip off a leaf and the necrosis didn't reappear - does this mean it's mold or is it just burn? The humidity is not high, so I don't know why or how mold would set in. My grow main light was too close, and the vents weren't cooling enough. Again, that too has been sorted out, and I have a new reflector hood. I'm now on the 5th node on some plants, and I wanted to put them into flower by this point, if things hadn't gone so dire. How bushy does a plant need to be for flower? I reckon a weeks more veg will make em look a lot better, I'll post pics of them then. They are still quite spindley.
Every plant is now growing well and looking great! Yay!! No deaths, I can't believe it, I really thought they were all going to die on me.
It is a very resilent plant and I am happy to hear things are looking better now! You should remove dead parts from the plant as they just provide a place for pests and molds to get a foothold. Often growers remove lower branches and leaves to create a space between the soil and the veg matter of the plant. This is because there is always mold in soil. You want it there actually but not up on the plants. The space between helps prevent it from climbing your trees.
