Hi guys just wondering if anyone could help. I'm growing a chocolope auto and for the last couple weeks the leaves have started turning yellow from the bottom up, and the top leaves have started going yellow around the tips. I was thinking it might be N def but my base nutes have N in them, I'm using plagron Terra grow and Terra bloom. Also the bottom leaves on my sour d are going yellow aswell.

Really hard to gauge anything with the lighting in the pics. Try a pic with the hps light off.
How much are you using of each of the grow/bloom nutes?
 
it is hard to see whats up with your lights on ^
usually, however, when that happens close to the beginning of flower, you haven't been feeding enough. the lower leaves going first say its a mobile nutrient problem, and that mobile nutrient is N.
take some pics under regular light, but i'm betting thats exactly your problem

I was suspect as well that they were fed bloom nutes through veg instead of stacking N or started P-K nutes too early in flower.
 
:wall:Heres a couple more out the tent. So how would I fix this do I give it more nutrients?
During veg I was giving 3ml Terra grow per ltr water so now I'm in flower do I give it full strength bloom or work my way up. I've been flapping in case it kills me girls

i feed regular veg nutes until i see good pistil formation, then i'll go half and half for a week, then change over to flower nutes.
once i switch to flower nutes, i'll do something like 500 ppm the first week, 600 the next, then up to 800 ppm for two weeks, then down to 400 till i think its almost done, the last week i'll just give it a little epsom salts at about 200 ppm, just so i know it has the sulfur it needs to do its finishing touches.
 
those don't look bad, if terra bloom has very low N, you might want to give them a little of the grow, but not a lot, maybe two half strength doses, then back to the bloom. i'd recommend a little calmag+, which has N as well, but if you're using flower nutes, they usually have a good bit of sulfur, which will screw up the calmag, you're better off just watering with weak veg nutes a couple of times
 
Oh rite I thought u had to switch to bloom when pistols first start. How do I fix the N problem? Do I have to give it just N or do I up the feed cheers
 
The npk in Terra grow is 3-1-3 and bloom is 2-2-4 is that alright I thought veg nutes had to have more N in
 
Its just a little hungry for N (veg nutes) where it was switched to bloom nutes too soon. Very basic rule of thumb you can follow.....continue to use the veg feed until stretch stops. Once stretch stops and flowers are present, bump up bloom nutes.
