Alrgt Pere man............. the issue from my experience is the tip burn and dark green fans point over nuting. This is the far left and the far right plants pere. The middle Dame, is obviously a much greedier than the outside two. As she is showing normal color and no tip burn Pere. The nercrosis at the end of fan tips indicates a Ec that is in exsees of 1.8-2.5....... and the dark green, indicates a lower Ph, and therefore higher nitrogen uptake...... try an Ec of 1.2 overall Pere, and runa 3-4 day water only flush. Then run a Ph of 6.6 in flower, and 1.2 Ec after flush....... keep in these ranges pere.....
Re small pots; due to confined space and low volume of media. Combined with heavy feeding of nute salts. especially if using high TDS tap water,(Ph over 8)............. the salts will build up in the media, leading to possible defs issues due to nutrient lock out, as Ph rises, or falls out of the desired range in the soil.
A good way of checking the issue is to check a good flush run of for high Ec. If your run of Ec is above 2.8, your ppm will be over 2000. get your run off Ec down to 0.9 ie, 650ppm@Ph/6.6 pere. And you should see better flower construction. After the f3-4 day flush. Flush to heavy run off and measure.
Run off ph 7.8
Flush at 5,8 untill run off drops
Run off ph 5.5
Flush at 7.5-8.5 untill run off ph rises
hope this is of help Pere............. will drop in to see if the adjustments show fruit, within 6-10 days ok....HB
