hi

its me again

i have just knowtised that one of my plants appears to have patch of yellow dots also brown ones on another leaf they are pretty central.

also 2 of my others the lower leaves are yellowing and one has a browning top i have been giving them a small amount of a well balanced feed containing all trace elements to make sure im not missing anything and i have been feeding on nitrogen and baby bio other than that

i cant see how i could have underfed them on anything unless something is locked up i possibly need to bring the ph of the soil down with some lime any suggestions on how much to add. also they are only in medium sized pots could this cause yellowing of the leaves and browing of the head any help would be appreciated.

thanks a lot

If they are tiny dots then it is prolly spider mites. Look real close at the leaves and see if you can see any tiny tiny red or black bugs. They usually start to make webs too. You might be better off removing the damaged leaves. Dont go crazy with it. Just take off what needs to come off.

tis not spider mites ive been there done that and lost a crop :P i poured boiling water through all my soil before i started and there is little chance of outside infection

another addition to my posts :P there is a picture of the damage in my pictures it is just of the head of the bad plant. the other plants just have yellowing lower leaves and yellow spots (turning into patches)

After looking at the pic I think you should flush or its too close to the light. When you put your hand there does it get hot?

no grow it about half the size you want it to be, it will nearly double in size during flowering. ps think im having same prob with my plant, was advised to flush, just waiting to see what happens now. good luck!!

im no pro but will offer advice if i might know.......

i got question what is it when most of the leaves are turning yellow and brown and get chrisp on the ends and the plant isnt in flowering...or yellow and black spots like leafs in september.....its not burnin,nor is to much fertilizer...

Pictures are worth more then words. I was thinking Calcium deficiency until you said they were not in flower yet. But then you said something about September.. That threw me big time, I thought,, oh,, out door grow,, Hmmmmmm. It is the end of December...
