please guys take a look at this problems getting worse and worse

i was told it was a ph problemit is a flood and drain ive emptyed the tank and renewed nutes im using ionic bloom there just over 6 weeks oldive added ionic boost at 1 ml per litre ppms are 700 ph is 5.8 as you can see bye the pictures the smaller leaves around the the buds are going slightly brown would this be more of a nutrient burn it started going a lighter green at the tips and working there way down the sides could someone please take a look and advise cheers

Pack,

They way I am interpreting the pictures is it appears to be nute burn (looks like it from what I can see). But you did a good thing by changing the water because a Ph lock often shows the same ill effects.

Be carefull when you have all of that dying matter in the flower sites because it can lead to fungus problems.

Keep us updated.

Well.....i can't really tell the color of the leaves from the picture and im not the best at diagnosing plants, but it could be a problem with the NPK ratio of your nutes. For my first few grows i would always start blasting them with bloom ferts as soon as they started flowering, and would eventually end up with nitrogen deficiency often times getting nute burn from too much Phos/Potassium at the same time. And then i found out that most growers start flowering with a mixture of veg and bloom nutes (cuz the plant is still doing a lot of vegetative growth at this point) and then shift the ratio away from nitrogen as the plant nears maturity.
maybe you know all this.. just throwing it out there.

I do F&D. Feel free to skip through my posts. I usually get a chance to get in some pertinent info in with the dirt growers. Never use more than 1/6 of the nutes per gallon as is what is recommended for dirt(1 teaspoon of mg for 6 gal.). 15min waterings, start to finish, usually three times daily. Start your ph at 5.5 for new water.Make sure there isn't anyway for water to pool in your table. You need to keep the res airated etc.

Nute burn, followed by possible lockout. Flush, flush, flush. Wait until nearly dry, add nutes back at about 30% less than before. Also, add a tiny bit of micro nute. Something like EJ's microblast. 600ppm sounds a tad high in soil for the look of the gals. I also believe I see a touch of previous nute burn. Err on the side of less! Happy growing to ya!

Those pictures show nothing definitive.
Could be nutrient burn.
Could be heat stress.
Could be Potassium deficiency. Could be cause by hard water. Could be caused by plants requirements. Could be caused my chloride ions in tap water.

I don't think they are looking that bad. I think running just good clean water through the system will help leach out enough of the salts, if any, that have built up. Then replenish your nutrients, go lighter on it (keep your ppms around 1000) and keep that potassium level higher than phosphate and nitrate. Make sure your pH stays solid and keep that room the right temperature and I think you and your girl will be just fine.
