Northern Lights 24 days into flowering and leaves yellowing
Hi Folks
Well, we have nearly made it on our first grow and we have two female Northern Lights plants that are about 3 and a half feet in height. Some basic info on our grow:
Using a 250 W fluorescent light
Growing in a general purpose garden compost from B&Q
Feeding using a chem fertiliser - B&Q general puirpose plant food which has a NPK ration of 5-5-5 and contains trace minerals
Have used organic bonemeal to supplement Ph levels
Watering using boiled tap water
Lights on a 12:12 with no interruption in dark period.
Temp maintained between 65-80
We started flowering on 1 February (24 days ago) and about 10 days ago some of the leaves started turning yellow.
At first we thought it was a Nitrogen deficiency as the yellowing was spreading from the tips but now we are not sure.
Have ph tested and it would appear the ph level is a tad under 7 so that seems ok (maybe very slightly high?)
So reading through the other posts on this forum it seems we could be over nutrilising or over watering and thus locking out nutrients? Or I thought perhaps that they might be root bound?
If they are root bound would it be a bad idea to repot them whilst they are flowering?
I would be grateful for any comments or opinions - there are a number of photos below which I have just taken which might help:DJCBrixton Reviewed by DJCBrixton on .
