Having Problems

zingzang · Oct 9, 2010

I had to move some of my plants into a soilless mix from a ebb and flow system to free up space. The plants that I moved also went into an attic and we have been having unusually high temps here over the last few days. I have fed them the same nutrients that they had in the hydro system but am having problems. I have watered them twice with just water, so they could be just hungry... or is it the heat? I have installed a duct system to move the air from a bathroom fan downstairs up into the tent and have a duct fan blowing out to get the air moving but I just installed the vent system today. Any help would be much appreciated

Thanks

I'm not really sure, but definitely doesn't look like a nute deficiency to me. More like a nute OD ;O)). I think i would flush it and start easy on the nutes when plant starts to grow normally again.

Thanks for your input, Most of the problems are at the top, is that consistent with nute burn?
Thanks again, I'm very much a newbe

it looks like both nute burn and high heat but the main problem is nute burn i dont think it was hot enough to hurt your plants i think that because of the nute burn the plant was just weaker to the higher temps.

Looks like my mate's plants when he had a salt build up from the nutes - flush the pots and ease off on the nutes for a little while.

It really does look more like nutrient burn. Depending on the soilless mix the pH could be off, and you might be using too many nutrients, locking up something.
If it is short on anything... and I'm torn on this... it'd be Potassium and Magnesium. The high temperatures indicate Potassium issues, along with the edge curling. The whiteness of the leaves points towards magnesium issues... but barely.

This could all be stress related as well.

Ride it out. Reduce your nutrients (not like the plant is so large as too need that much nutrition). And obviously get the temperature down as quick as possible

Now that I think about it, this could just be heat stress and heat damage. Deal with that first, nutrients next.

Either way, flushing and easing off with the nutes is the best option. If it was heat stress the leaves would curl inwards.

Thanks bros, the flushing has started
